Milling is a machining process that can create detailed or complex shapes from metal, plastic, or other materials. The CNC milling process involves using a computer to control the motion of a rotary cutter that removes material from a workpiece. This article will discuss things you need to know about the CNC milling process.
CNC milling is a machining process that uses computer numerical control (CNC) to cut materials precisely. It can produce complex shapes with high accuracy and repeatability from metal, plastic, or other materials. It is used for many applications, including prototyping, manufacturing parts, making moulds and dies, creating fixtures for production lines, producing 3D sculptures and more.
The most significant benefit of CNC milling is its ability to produce exact parts with tight tolerances. Other advantages include speed and consistency in production and flexibility in design since it can be automated easily compared to manual operations. Additionally, because it supports multiple types of machines with different tooling, it is a versatile solution for many manufacturing needs.
There are many different types of CNC mills available today, including vertical and horizontal mills. Vertical mills are designed for operations that require cutting or drilling straight down into material and have a spindle axis perpendicular to the table. Horizontal mills are designed for operations in which the workpiece is fed parallel to its length along an x-y axis.
CNC machines can mill nearly any material, from aluminium alloys to plastics, composites, and even hardwoods. It is essential to consider the specific properties of your material when selecting the best tooling for your application. Generally speaking, more complex materials such as steel require more specialized tools, while softer materials can be machined using standard-issue tooling.
CNC milling is often carried out in multiple passes, depending on the complexity of the design and material being milled. The most common techniques used in CNC milling include rough cutting, finishing, slotting, drilling, and engraving. Each technique has its tools that must be chosen based on the workpiece material and desired finish.
When looking for a CNC milling service provider, one must consider their experience with CNC machines and the type of parts they specialize in creating. Additionally, it is vital to look for certified CNC milling service providers with an established quality management system. Doing your due diligence on a CNC milling service provider will help you find the best fit for your application.
Safety should always be the top priority when operating a CNC machine. Proper training and use of personal protective equipment, along with regular CNC machine maintenance, are necessary to ensure safe operation. It is also essential to be aware of any hazardous materials or processes used during CNC machining so that proper precautions can be taken.
CNC machinists typically use CNC software programs to design and create their components. Popular CNC software programs include CAMWorks, Mastercam, Fusion 360, and Autodesk Inventor. Each CNC program has its own tools and capabilities that allow CNC machinists to create the exact parts they need for a given application.
When selecting the suitable CNC mill for your needs, it is essential to consider how precise and repeatable the parts will need to be. You must also consider what type of material will be machined and any special features that would benefit your application. It is vital to work with a CNC milling service provider with experience in the type of part you are trying to manufacture so that they can advise on the best CNC machine for your needs.
When getting started with CNC milling, it is essential to clearly understand the project goals and machining requirements. You should also be familiar with CNC machine operations, such as setting up tools and measuring material properties. It is also essential to have a plan for managing data so that any changes made during CNC machining can be tracked. Finally, it is beneficial to practice CNC milling on scrap materials before attempting to machine a final product.
CNC milling is a versatile machining method that can be used to create a variety of components from soft and hard materials. It is vital to research CNC machines, CNC software programs, and CNC milling service providers to find the best fit for your application. Additionally, safety considerations, as well as tips for getting started, should also be taken into consideration when beginning CNC machining projects. With the proper knowledge and equipment, CNC milling can open up many possibilities regarding part design and production capabilities.
Hi Guys! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through Electronics DIY Projects to Improve Work from Home.
Electronic devices are not cheap and rightly so. Since you require advanced setup and technical skills to build something sophisticated and delicate. The good news is that you don’t have to spend a fortune on such devices since DIY electronic projects are the solution. You can make similar electronic projects you find online at home and save a lot of money. Some people prefer working on a breadboard while others prefer building on printed circuit boards. However, if you’re new to this field, we’ll suggest you start from the breadboard, before building your projects on the PCBs. The good thing is that you don’t require a big setup or advanced tools to work on breadboards. Basic computer knowledge and a few tools and electronic components would suffice.
Know that nearly all of these electronics projects can be developed in less than a day if you have the required tools and components. It won't be difficult to test out these creative ideas for electronics projects because, fortunately, you can search hot electronics parts from kynix for a low price.
I suggest you read this article all the way through, as I’ll be covering in detail electronics DIY projects to improve work from home.
Let’s get started.
The long, warm months ahead can only mean one thing for DIY enthusiasts: polishing up the skills over the project after project. For some people, that can include finishing a picture or creating original dishes in the kitchen. And for tech nerds, it is learning new software or building electronic projects at home.
Looking for easy ways to spruce up your technical skills? These simple DIY Electronic Projects would help you to get your hands dirty in the electronic field without spending a lot of time and money.
This is a simple electronic project used to charge your lead acid battery. It comes with LM 317 which is the main component of the circuit that serves as an operational amplifier mainly employed to deliver the exact charging voltage to the battery.
Operational Amplifier LM 317
Transistor BC 548
Transistors
Capacitors
Potentiometer
LM317 provides the correct voltage for the circuit and the transistor BC548 is employed to control the charging current delivered to the battery.
It is worth noting that one-tenth of the Ah value of the battery must be charged - the basic idea behind charging this circuit. The charging current can be adjusted using the potentiometer R5. While Q1, R1, R4, and R5 regulate the battery's charging current. The current flowing through R1 rises as the battery charges and it changes how Q1 conducts. The voltage at the LM 317's output rises because Q1's collector is connected to the IC LM 317's adjustment pin.
The charging current is reduced by the charger circuit after the battery is fully charged, and this mode is known as trickle charging.
Signal transmission is crucial when you want people to hear someone from a distance. Especially in factory and college settings to allow people to hear programs and speeches within range. This is a low-cost, simple electronic project used to create an FM transmitter circuit that has a 2-kilometer range for signal transmission.
Matching Antenna
Transistors BC109, BC177, 2N2219
Capacitors
Resistors
Battery 9 to 24 V
This is a simple DIY electronic project that you can easily develop at home. It comes with a 2 km range for transmitting the signals.
In this setup, a 9 to 24 DC power supply battery is used to power the circuit which not only ensures the optimum performance but also helps in reducing the noise.
The traditional high-sensitive preamplifier stage is formed with the transistors Q1 and Q2. Know that the audio signal required to be transmitted is connected to the base of Q1 using capacitor C2.
The oscillator, mixer, and final power amplifier functions are all carried out by transistor Q3. And the biasing resistors for the Q1 and Q2 preamplifier stage are R1, R3, R4, R6, R5, and R9. The tank circuit, which is formed by C9 and L1, is crucial for producing oscillations.
The FM signal is coupled to the antenna by inductor L2. Recognize that, the circuit frequency can be adjusted by varying C9 and R9 is employed to adjust the gain.
Make sure you apply this circuit on good-quality PCBs, as poor-quality connections can hurt the overall performance of the circuit.
Tired of your speaker’s low noise? Don’t panic! Since this is another easy-to-design electronic circuit that provides 150W to the four Ohm speakers – enough to provide you with a lasting, ruthless buzz to rock and roll. The basic component of the project is the pair of Darlington transistors TIP 142 and 147.
Darlington transistors TIP 142 and 147
Transistor BC558
Resistors
Diode 1N4007
Electrolytic Capacitors rated at least 50V
This circuit is effective for those just starting in the electronic field. In this circuit, TIP 147 and 142 are complementary Darlington pair transistors known for their durability that can handle 5 A current and 100V.
Know that Q5 and Q4 of two BC 558 transistors are joined together as a pre-amplifier also called a differential amplifier. This is used for two main reasons: for providing negative feedback and for reducing the noise at the input stage, thus improving the overall productivity of the amplifier.
While TIP41 (Q1, Q2, Q3) and TIP 142, TIP 147 together are employed to drive the speaker. This circuit's construction is so robust that it can be put together by soldering directly to the pins. A dual power supply with a +/-45V, 5A output can power the circuit.
A siren is a device that produces a usual louder sound to alert and/or attract people or vehicles. Typically, ambulances, police cars, fire trucks, and VIP cars are among the vehicles that use the siren.
The basic component of the project is the 555 timer which is one of the most adaptable chips that can be applied in practically all applications because of its multi-functionality. It is an 8-pin chip with a 200 mA direct current drive output that comes in a DIP or SOP packaging. This IC is a mixed-signal semiconductor since it has both analog and digital components. The IC's primary uses include producing time, clock waveforms, square wave oscillators, and numerous more functions.
Using two 555 timers, speakers, and a basic circuit, this breadboard project creates a police siren sound. As indicated in the diagram above, an 8 Ohm speaker is connected to two 555 timers.
Note that, one 555 timer is attached in an astable mode (it carries no stable state, instead comes with two quasi-stable states which quickly change from one state to another and then back to the original state) and the second 555 timer is connected in the monostable mode (one of the two states is stable, and the other is nearly stable.
When a trigger input is applied, it changes from a stable state to a quasi-state and then returns to the stable state on its own after a certain amount of time) to achieve the appropriate frequency.
This setting creates a siren with a frequency of about 1 kHz. Using the knob in the circuit, the siren sound frequency can be changed to match the police siren sound. The siren is used not just in automobiles but also in many businesses, mills, and other establishments to notify workers of their shift times.
With the help of a few basic components, a cooling system to regulate a DC fan is designed in this simple breadboard project. The goal of this project is to build a cooling system by easily operating a DC fan without the need for microcontrollers or Arduino, but rather by using readily available and straightforward electronic components. Once the temperature hits a certain level, this fan will turn on.
5V DC Fan
5V battery
NTC thermistor-1 kilo-ohm
LM555 Timer
NTC thermistor-1 kilo-ohm
BC337 NPN Transistor
diode 1N4007
capacitors 0.1 uF & 200 uF
LEDs
Connecting Wires
Resistors like 10k ohm, 4.7k ohm, 5k ohm
Breadboard
In this circuit, the DC fan can be controlled using a thermistor. The resistance of the thermistor, a particular type of resistor, is largely dependent on temperature. Thermistors come in two main types including NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient).
When an NTC is employed, the resistance decreases as the temperature rises. This is the opposite in the case of PTC where resistance and temperature are directly proportional to each other.
When the temperature reaches a certain threshold, the fan turns on. The first LED, "The green LED," which indicates rising temperature, will turn ON as the temperature rises.
The second LED will turn ON when the temperature reaches the second threshold, and the fan will run as long as the temperature is over the second threshold. The fan will continue to run for a set amount of time once the temperature returns to an acceptable level.
This simple LED chaser circuit is developed using a 555 timer and 4017 IC. Together, the two ICs in this project run the LEDs in a sequence to create the illusion that they are chasing each other.
555 timers
CD 4017 IC
Resistors 470R, 1K & 47K
1uF capacitor
Connecting Wires
5 to 15 V power supply
Breadboard
Before you start working on the project, you must visit the pin diagrams of both ICs. It will help you to identify the correct pins to be used in the project.
When an IC – a 555 timer – is used in an astable mode (that produces a square wave), its output fluctuates continually between high and low supply voltages. For instance, an LED will continuously blink if it is connected between 555 timers and the ground.
The CLK input of a decade counter is connected to the output of a 555-timer IC. This IC has ten output pins, each of which is wired to an LED. The remaining output pins will all be switched OFF once the first pin is turned ON.
This simple, low-cost traffic lights model circuit is designed using two 555 timers and some other basic components.
This circuit comprises three LEDs for the indication of RED, Yellow, and Green traffic light signals. First, it will turn ON a green LED, maintains it on for a while, then briefly turns ON a yellow LED before turning on a red LED that remains ON for almost the same amount of time as the green LED.
555 Timers
Resistors of 100K, 47K, 2 x 330R, 180R
LEDs – Yellow, Red, and Green
Connecting Wires
Power Supply 5-12 V
2 Capacitors of 100uF
Breadboard
The circuit comes with two astable circuits where the first astable circuit will power the other. Therefore, only if the first 555 timer IC's output is ON will the second 555 timer IC be powered.
When the output of the first timer remains at 0V, it will turn ON the red LED. The green LED turns ON anytime the output of the second 555 timer IC is at a positive voltage, and the yellow LED will turn ON when the second 555 IC is in discharge mode.
The yellow and green LEDs would turn on at the same time. However, even before the voltage across the capacitor of the first 555 timer IC reaches two-thirds of the supply voltage, the output of the first 555 IC goes off, which will allow the red LED to turn ON and the yellow LED to turn OFF.
Hope you’ve got a brief idea of how to get started with electronic projects.
Getting hands-on experience will not only improve your technical skills but also help you to develop critical thinking to get familiar with advanced electronics.
It’s okay to become acquainted with PCBs, but if you don’t know how to solder properly or how to design a good PCB layout, it’s preferred to start working on the breadboard to keep your project up and running.
That’s all for today. Hope you’ve enjoyed reading this article. If you’re unsure or have any questions, you are welcome to reach out in the section below. I’d love to help you the best way I can. Thank you for reading this post.
Hi Guys! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through How a Hobbyist Can Work on Electronic Projects in America.
Working on electronic projects is a bit inundating.
From selecting the topic to research work and development to execution, you need to hustle, grind and drill to keep your final product up and running.
When you are new to the electronic field, you must not be afraid to get your hands dirty in diving deep into the nitty-gritty of the project. This means that no matter what kind of technical project you pick, you need to spend a significant amount of your time and money to reach your final goal. It's not just about making sure that whatever it is you're looking for is done well—it's also about making sure that your project is done right from the start.
I suggest you read this post all the way through as I’ll be covering everything you need to know to make electronic projects as a hobbyist.
Development of electronic projects is tricky especially when you lack direction or you’re overwhelmed by the options available online. You can pick from a range of projects but the main goal is execution. If you fail to produce something that you proposed initially, it’s not worth it. NOPE. It’s not a good idea to pick the most difficult project to impress your instructors. Choose what resonates well with your expertise and helps you grow and excel in your field.
Newcomers have so many questions when they are about to get hands-on experience on the project. They don’t know how to start without lacking enthusiasm throughout the entire process. Don’t panic! We’ve streamlined a few steps in this post that will help you to complete your electronic project from start to finish with a proper strategy in place.
Whether you’re working alone or in a group, it all starts with brainstorming a few ideas. If you’re working in a group, make sure you work on concepts with shared interests and common grounds. Having a fruitful conversation before picking up the topic will help you figure out everyone’s weaknesses and strengths. What you lack in one area may well be covered up by someone good in that field. And if you’re aiming to develop something amazing for your final year project, this is a great opportunity to leave some sort of legacy for your juniors.
The following are the key considerations while brainstorming ideas for your electronic project.
Must be doable. You must have abilities to turn your thoughts into reality.
Start with something new. With the recent advent of technologies, there is a scope for covering something that has not been discussed before. Try incorporating microcontrollers and Arduino boards into your projects with new peripherals.
The best idea could be where you address the problem and provide a solution.
Cover both hardware and software. This is important. Covering both aspects of the project will not only polish your skills but also leave room for improvement for your juniors to work on.
Within price range. Yep, it should be well within your budget. Though you can ask for sponsorships if you want to produce something from a commercial aspect, still it’s wise to pick something that you can easily afford.
Should be completed in due time. That’s true. Deadline is important. Of course, you wouldn’t want to spend your money, time, blood and sweat that you can’t submit within time.
Once you’ve finalized the project idea, it’s time to play… Yeahhhhhh! Yep, it’s time to plan your project.
Say, if you have six months to complete your project, then divide the whole duration into dedicating each aspect of the project to a specific time limit. For instance, spare two months for research purposes, the next two months for purchasing the components and development of the project, and the final two months for the testing and execution of the project.
It is observed most engineering don’t plan their project according to the time limit and in the last month, they will be scratching their heads and doing everything to run the project. Even I did this mistake in our final year project. And we had to ask for extra days from our instructor to complete our project. So, I suggest you… please don’t do this mistake and plan your project accordingly.
Until now, you’ve selected the topic and planned the project. Now comes the research part. This is the backbone of the entire project. Start your research with what’s required to be included in both hardware and software.
Your time and energy are wasted when you rely on an inaccurate source of information. To research a subject with confidence and to cite websites as support for your writing, you should streamline your research to gain a clear understanding of the subject.
Make sure the hardware components you select are available in the market. And even if you have to buy them from outside the country, you spare enough time to incorporate them into your project.
Thoroughly go through the datasheets and pin diagrams of the components and look for possible substitutes. Why use an expensive part when a cheap substitute would suffice?
Apart from finding the components from the local market, there are scores of places online where you can get the right products. Some are better than others. But how do you differentiate them when all claim to be the best? Don’t fret! You can use Utmel Electronic Online Store which gives you quality electronic parts and components at reasonable prices to support your electronic project. From batteries, audio products, and connectors to capacitors, transistors, and evaluation boards, this place is a haven for tech nerds.
Hardware development is not a linear process. Sometimes you’ll witness going two steps backward for every step ahead. Don’t fear when this occurs since it’s what is required to turn your imagination into reality. Making hardware includes both: creation of mechanical structures and electrical circuit development.
The first step in developing the mechanical structure is making the 3D model on the computer. You can use “SolidWorks” to create the overall exterior of the project. Once you design the 3D model, turn it into a physical prototype. You can only create the model in the software but most probably, you will require someone in the market adept in understating the complexities of injection molding. Since this process is a bit tricky with many rules and regulations to follow.
If you’re a beginner and are not familiar with the nuts and bolts of developing PCBs, it’s wise to first create your hardware on the breadboard. This will help you identify all the possible mistakes before installing all these components on the printed circuit boards. Moreover, breadboards are user-friendly and you don’t require advanced technical skills to run your project.
PCBs are the cornerstone of many electronic and electrical units that provide a pathway to reduce their technological size. A PCB is often made of laminated materials like epoxy, fiberglass, or a variety of other materials that provide an essential framework for organizing electronic circuits.
You need to design your PCB to create PCB layouts. Print out your PCB layout on the glossy paper and transfer that print onto the required size copper plate.
Make sure you place the main IC into the center of the board to allow even connections with all the electronic components.
You have developed the required hardware for your project. Now is the time to use your programming skills to run your hardware.
If you’re using a microcontroller or Arduino, you might need to learn C++ since Arduino code is written in C++ with the inclusion of special functions. The code you build on the software is called a ‘sketch’ that is compiled and processed to machine language to run your hardware by the instructions given by the human input.
Similarly, if you aim to create development boards, MATLAB software is used which is quite handy for Data analytics.
A PCB and electronic design automation software suite for printed circuit boards is Altium Designer.
All circuit design activities can be completed using the tools in Altium Designer, including schematic and HDL design capture, circuit simulation, signal integrity analysis, PCB design, and the design and development of embedded systems based on FPGAs. The Altium Designer environment can also be modified to suit the needs of a wide range of users.
I don’t highly recommend this trick but if you find yourself stuck in some part of the hardware or software development, you can outsource that part to freelancers. But this is highly risky since if your instructor finds out that you were not the one who did that part, you may get into hot waters. Make sure you get your instructors on board before outsourcing the most complex part of the project.
You might have done everything right from the start, but it’s unlikely that your project starts in one go. You might need to run your project through a series of test and trial methods to identify errors and glitches in both hardware and software.
Always create a backup plan. Make your hardware in such a way that if you require some modification in the process, you can do so.
For instance, you can make a plastic casing for your mechanical structure before going for the hard metal enclosure. Ensure that the end product resonates with what you initially proposed in your proposal.
Once your project is completed and carefully tested, next comes the writing process.
Anyone can write but good writing needs practice. Make sure you dedicate this part to someone good at jotting down ideas in a clear and meaningful way.
Since the audience will get to see the end product. They don’t care how many struggles you withstood and how many sleepless nights you went through, they care about how your project can be beneficial for them and how it can solve their problems.
Additionally, it’s all about presentation. If you don’t know how to skillfully present your project, you fail to convince the audience that your project is worth spending time and money on.
It will be helpful to use data visualization in your presentation to present your project clearly and concisely. Throughout your presentation, be ready to respond to the panel's queries with care and attention.
And finally, don’t forget to make a video of your running project. Sometimes, even though the project runs smoothly, it doesn’t execute well in front of the instructors. So it’s wise to be on the safe side and record the video of your project.
You can make a home automation IoT project to remotely control the appliances of your home.
You can build an automatic security system that informs you whenever someone trespasses your home boundaries.
Develop an advanced light system that can be used to turn on the light loads whenever they detect human presence within range.
You may also create a robotic metal detector system that can find metals in the ground, and inside food products with the help of radiofrequency technology.
Build automatic solar tracker. To make sure your panel receives the most radiation possible throughout the day, you can construct trackers that follow the sun's path from sunrise to sunset.
Make Wireless Lock System Through OTP that provides a smart security solution.
Still reading? Perfect.
It means you’ve learned some valuable insights into how to develop your electronic project from start to execution.
Just follow these steps and you’ll be well ahead in turning your idea from ideation to execution.
Start with a simple doable idea. Some ideas may look best initially, but when you start working on them they become unrealistic.
Don’t forget to ask for help if you get stuck in the process. Since when you never ask for it, the answer is always NO.
That’s all for today. Hope you’ve enjoyed reading about how a hobbyist can work on electronic projects in America. If you are unsure or have any questions, you can ask me in the section below. I’d love to help you the best way I can. Thank you for reading the article.
Metal fabrication refers to the manufacturing of sheet metal and other types of metal to fit different shapes.
The metal fabrication industry is vital to a wide range of industries. That’s due to the reliance on metal fabrication for vehicle parts, train tracks, building equipment, electrical devices, etc. A metal fabrication shop has various pieces of equipment needed to design and fabricate a myriad of metals. So, what, then, is custom fabrication?
Custom metal fabrication refers to the production or fabrication of a range of metals to meet unique specifications. Custom metal fabrication projects are carried out for a specific purpose. It involves cutting, bending, rolling, or joining metal to create custom complex shapes based on specific requirements.
Unlike traditional metal fabrication, custom metal fabrication offers more flexibility to meet the product specifications for various industries. It can be used to create tools for construction, mining, aerospace, and energy delivery systems .
Custom metal fabrication offers certain benefits over stock metal fabrication. It can be used to create precise fabrications for use in rail systems, building equipment, automobiles, and many other purposes.
Here are three major benefits of custom metal fabrication:
Improves Product Quality: You can produce durable metal products through custom fabrication. Metal fabricators consider the best materials that can suit the desired application.
Factors such as external forces, stress, and possible strains are also considered during the production process. For custom metal fabrication, the design is application-centered. The custom metal fabricator uses materials that can ensure increased product quality.
Increases Metal Fabrication Efficiency: Instead of using mass-produced metal works for certain services, custom fabrication drives efficiency by producing specialized designs. It allows for the creation of metal structures using a process that suits the requirements the most.
This helps increase efficiency and reduce the time spent on metal fabrication. Also, custom fabrication allows for optimized product processing and product flow. It makes the best use of metal fabrication materials in the production line.
Offers High Component Compatibility: Another major benefit of custom metal fabrication is the high component compatibility it offers. In custom fabrication, the metal works are designed to meet the required specifications, making them compatible with each other. With custom metal fabrication, you can produce custom shapes that work with the hardware you are using.
There are different types of metal fabrication processes. These processes are unique and are utilized based on part geometry, the metal fabrication materials, and the purpose of the product. Below are the common types of metal fabrication processes.
Casting: Casting involves pouring molten metal into a die or mold. The molten metal then cools and hardens into the desired shape. Casting is ideal for the mass production of metal parts with the same shape, for example, in the production of train tracks.
The mold can be reused multiple times to create metal works that are of the same shape. There are different types of casting processes, such as die casting, permanent mold casting, and sand casting.
Cutting: Cutting is one of the most common metal fabrication processes. It involves cutting a large piece into smaller pieces of metal. While sawing remains the traditional and earliest method of cutting, there are other methods, such as laser cutting, waterjet cutting, and plasma arc cutting, among other modern cutting techniques.
Cutting can be done through manual and power tools or through computer-controlled machines. Usually, cutting is the first stage in a metal fabrication process.
Drawing: In drawing, a piece of metal is pulled through tensile force. It is then stretched into a thinner shape. Drawing can be performed at room temperature or at heated temperature. It is known as cold drawing when it is done at room temperature.
However, the metal can be heated to reduce the tensile force needed. Drawing is usually combined with sheet metal fabrication to create box-shaped or cylindrical vessels.
Drilling: In drilling, a rotary cutting tool is used to cut holes in a piece of metal. The drill bit rotates very fast to make a hole in the metal.
Extrusion: In extrusion, the piece of metal is forced between or around a closed or open die. The diameter of the metal will be reduced to the cross-section of the closed or open die if it is forced through.
However, if the metal is forced around a die, it will result in a cavity. The two methods involve a metal slug and a ram to perform the process. Usually, the resulting product is used for piping or wiring. For example, it can be used to create splice kits needed to splice cable.
Extrusion can also be used to create short or long metal pieces. Also, it can be performed at room temperature or at increased temperatures. Cold extrusion is typically used for steel metal fabrication, while hot extrusion is commonly used for copper fabrication.
Forging: This involves the use of compressive force to create metal pieces. The metal fabricator uses a hammer or die to hit the workpiece until it forms the desired shape. It can also be done using high-pressure machinery.
Milling: Milling involves using rotating cutting tools to make perforations into the metal until it forms the desired shape. Usually, milling is done as a finishing or secondary process. It can be done through a CNC machine or manually. There are different types of milling, such as climb milling, form milling, angular milling, and face milling.
Punching: Turrets with unique shapes hit the metal to create metal pieces with holes or shaped metal pieces. It can be used to create delicate metal decorations or for other purposes.
Turning: In turning, a lathe is used to rotate the metal, while a cutting tool is used to shape the metal radially while it spins. The angle of the cutting tool can be adjusted to make different shapes.
The metal fabrication industry caters to many other industries. Metal works are used for different applications, such as rail works, buildings, and other projects. Custom metal fabrication involves applying metal fabrication processes to make specific metal works.
The major benefits of custom metal fabrication are improved product quality, increased metal fabrication efficiency, and high component compatibility. The unique metal fabrication processes are used for different purposes to create specific products. It is important to look for experienced companies with specialized equipment when looking for a metal fabrication service.
A lot of people took engineering for the love of math and machines. Most are introverts as well, diligently doing their project in workshops, plants, or computers. Unless you are in sales, academia, or managerial positions, you don’t meet a lot of people as much as a doctor or a lawyer.
However, this should not stop you from establishing your network. People networks may not be the most popular engineering tool. Albeit, you might be surprised by how useful and powerful it can be.
The good thing is that there are contact management apps nowadays. You can compartmentalize your contacts- suppliers, specialists, laborers, and so on. With the right contact management app , you can reap the following benefits.
Referral fees are sweet. Receiving a check from an old acquaintance because you recommended them to the project you are currently working on may not be an SOP but if it comes, you have the budget for a fancy dinner or a family vacation, all depending on how much you receive of course.
It is ideal to establish your network early, like during your university years. That is when you meet other students taking up engineering courses. For example, you took civil engineering and later, got into residential projects. Someone from the electrical engineering class may be into developing housing units as well. You can easily refer him to your developer because you have an idea of how he performed way back in the undergraduate days and most likely carries a good professional portfolio as well.
Deep but narrow or wide but shallow, that is the question. However, this is the age of information and we can easily swim to different waters. There might be electrical theories that can be tried on fluid flow, especially when you understand voltage deeply. And vice versa.
Knowledge of chemistry may be beneficial for material engineers. Marine engineers may take notes from a marine biologists about how different aquatic life functions so that first can improve their work more.
It’s not imperative that you are in-depth with other fields. The key is knowing who is an authority in those other fields. You just have to be able to ask the relevant questions and understand the basic terminologies in order to sustain a professional collaboration.
It is nice to have a reliable circle that can give technical opinions about your innovations. Peer review helps improve your new machine or novel methodology discovery. After you have performed your calculations and achieved repeatable results to make a conclusion, a review not only from your mentors and colleagues but as well as from other stakeholders or possible users would be beneficial.
If you have a good network, getting insightful feedback would be easy to come by. This would be great especially on product development as usually, you need fresh eyes on something you have been working on for a long while.
When you are operating in the same environment for a long time, it’s difficult to scale how your practice and proficiency translate to the outside world. Connecting with other professionals allows you to get a better understanding of how other people in similar positions go on to have more successful careers. This is called upward comparison. This psychological theory implies that when people compare themselves to someone they perceive to be superior, it motivates them to gain similar achievements.
If you’re eyeing a C-level post in the company on the career ladder, it is not enough that you know only what your institution demands for such a position. Your fellow engineers would be aware of those needed upgrades as well. On the other hand, your connection with several engineering managers even from other industries can be beneficial. It gives you more knowledge regarding people aspiring to be principal engineers than your work colleagues. When one from your network finally gets promoted, you can either directly ask him what he did or simply note the certifications he took and the achievements he fulfilled.
Engineers in the technical field don’t need to accumulate contacts for their work consciously. However, if you will compile all the various suppliers showcasing their innovative designs, the numerous specialists servicing that instrument, or even the more than a dozen consultants that you need signatures from, you might be surprised to know you can already fill an A0 size paper with their contact information and more.
You don’t necessarily need to be at a friend level with all of them. Just keep their calling cards instead of inattentively giving them to the document controller. Better yet, have a contact management app that offers the option to store not only contact typical contact details but also some notes about the person.
Let’s say you’re a building engineer. A salesman walked into your office in order to have a product demo about a new technology in waterproofing. Instead of focusing solely on the technicalities of the product, you can get a little more pleasant with the salesperson and maybe you’ll be able to get better deals than the ordinary sales pitch.
Network, network, network. This is not exactly taught in engineering economics but business graduates already know. You can set up your consultancy in a prime location. However, if your brand is unpopular, you’re just making one person rich: the landlord.
You may have the most efficient system design, but nobody will hear about it if you can’t market it properly. Hence, you will hire a marketing officer and what does he have to do? Build a database of people where he can sell your product.
If you already have accumulated and organized contacts, you don’t have to put up much effort to find initial clients. You save the budget to hire a marketing officer for later when you want an expansion.
It may be HR’s job to hire and fire technicians and laborers. However, keeping a record of all the workers you’ve handled may come in handy.
If you start your own company, it will be easier to have a ready list of employees you want to hire. Pulling up a list of personnel from your phone is more convenient than tracking them one by one after a long time.
Another case in point is as the project is near to end. It is normal to reduce manpower hence some of your team members will have to be let go. Your list of good workers can easily be shared with your other fellow engineers who are just at the peak of their work at another construction site. You share your manpower like you (sometimes) lend your tools to other engineers.
Later on, when you are the one needing extra manpower to recover lost hours due to force majeure, you can easily pull some guys without question on the quality of their work. This mitigates the risks of poor workmanship and possible unprofessional conduct as you have worked with these crews before.
It’s never too late to build your people network. You can gain this new skill set or upgrade your basic knowledge with the help of some contact management tools. Do so and reap more of the benefits of human connections.
Hi Guys! Hope you’re well today. Happy to see you around. In this post, I’ll walk you through What is CNC Machining? It’s Definition, Processes & Types & Components.
CNC (computer numerical control) machining has been around for a while. It is a manufacturing process where machine tools are guided and controlled by computer software. High efficiency and better control make this process ahead of the manual handling of the tools. CNC manufacturing is done by sophisticated, complex machines that guarantee the formation of the final product with high precision and accuracy. Different CNC machines are used to treat different parts, however, each machine makes use of computer-guided software to precisely dictate and handle the machine tools. It is worth noting that the CNC systems are dynamic in nature which means new prompts can be included in the pre-existing code which is edited and programmed by the programmers.
Curious to learn everything about CNC machining?
Well, you’ve come to the right place.
Keep reading.
CNC machining is a process that involves the automatic control of machine tools through a computer to shape the material into the required form. During this process, machining equipment like latches, routers, mills, grinders, and drills... run in accordance with computer instructions. After setting up the machine and loading the program into it, the procedure is automatic and doesn't require any human involvement. To create several items with the same accuracy and precision, the production cycle repeats itself to produce the desired shapes. The parts can typically be produced and supplied in a matter of days, saving both money and time. The most cost-effective method for creating unique parts from metal materials is CNC machining.
Don’t get confused between CNC machining and 3D printing. They are different even though both are used to create distinctive shapes. In the subtractive process of CNC machining, the material is taken out of the workpiece to create a certain shape. On the other side, an additive method is used in 3D printing to add material to make precise objects.
A vast variety of materials including plastics, metals, composites, wood, foam, and glass, can be machined using CNC technology. The basic goal of this method, sometimes referred to as digital manufacturing, is to produce items that are uniformly precise and accurate.
There are four fundamental processes in CNC machining. A 3D model of the object is first created using CAD software. The second stage involves converting the digital CAD file data into a CNC program, sometimes referred to as G-code. Setting up the machine for the desired actions is the third phase. Finally, machine tools automatically operate on the workpiece to remove material and turn the workpiece into the appropriate shape,
Find below each process one by one.
The CNC machining process begins with the 3D solid part design. Utilizing CAD software, where the technical details of the pieces are established, 3D modeling is carried out. Notably, when developing 3D items, designers and manufacturers must take the capabilities of CNC machines and their tools into account.
Most tools are typically cylindrical and can only be used to create curved corner portions. As a result, the design process has a limited range of part geometries. The ability of the machine to hold the workpiece and the material's characteristics, such as the maximum part size, the minimum part thickness, and the complexity of the interior features, also play a role in the CNC machining process.
The 3D model of the solid part is produced by CAD software, and it is exported in the STEP or IGES CNC-compatible file format.
A CAM (computer-aided manufacturing) program processes the created 3D CAD file to extract the part information and produce programming code known as G-code. This code specifies the operations carried out on the solid material to produce the special portion. The timing of the tool movement, the depth of the cut, the path the tool follows when it is turned on and off, and other instructions are applied to the tools in this area to remove material from the solid workpiece and produce the desired shape.
The worker feeds the G-code into the machine after converting the CAD file.
Before the employee applies the program to the tools, the machine needs to be set up properly. This entails tightly holding the workpiece using the spindles of the machine. The overall machining process will be impacted if the holding device fails to keep the material in place. Therefore, ensure that machine spindles operate precisely with no space for error.
Additionally, make sure the appropriate instruments, such as drill bits or end mills, are attached properly. Once the machine is configured, the employee uses the G-code that is provided to carry out the basic tasks programmed into it.
This is what we have done so far. We have created the CAD file and converted it into G-code. Then make the setup.
Now the real process begins.
In this stage, the worker initiates the computer program that enables the tools to conduct specific operations on the solid material. To create specific shapes, extra material is eliminated from the workpiece. Plastic consumer goods, simple wooden decorations, steel aerospace parts, and intricate metal automobile parts can all be produced with CNC machining.
A variety of industries including agriculture, construction, aerospace, and more use CNC machining – a digital production technique. The technique includes numerous computer-controlled automatic machining operations. The following mechanical processes are frequently used in CNC machining:
Drilling
Milling
Turning
As the name suggests, drilling is the technique of making several cylindrical holes in the workpiece. The drill is used in this process parallel to the workpiece. The drill bit revolves while exerting pressure vertically on the workpiece plane when the operator runs the program. The drill bit produces holes with a diameter equal to its width. You can choose from a variety of drill bits to treat the material's surface. Using specific work-holding devices and machine settings, you can do angular drilling operations in addition to vertical drilling operations.
Multi-point cutting tools are used during the milling process to trim away excess material from the workpiece. The milling process is separated into two primary stages based on operational capabilities. The first is face milling, in which the tool carves solid material from shallow, flat surfaces. The second method is called peripheral milling, and it involves making deep slots and threads in a solid workpiece using a tool.
Turning is a type of CNC machining where the material is removed and the required shape is formed using single-point cutting tools. For turning operations, where the cutting tool is applied linearly to the solid rotating object, CNC lathe machines are employed. The turning process creates slots and taper threads.
Hope you’ve got a brief idea of what CNC machining is all about. In this section, we’ll discuss the types of CNC Machining.
In particular, CNC machining is divided into 5 different types that are performed on 5 different types of machines.
The main aim of every machine is to reduce human input and make the process automatic with instructions from the computer. CNC machines are preferred over non-programmable machines since they can produce parts in volumes in less time with better precision and accuracy.
Read on to find out the five types of CNC machines and how they work.
CNC lathe and turning machines are mainly known for their ability to rotate objects during the machining process. These machines feed their cutting tools around the revolving bar stock in a linear motion, removing material from the circumference until the required diameter is achieved. One of the key benefits is that they can easily position the X, Y, or Z axes while doing a variety of jobs. These axes allow the machine to move the component as per its geometry.
The desired internal and external features of the object can be formed using these machines including reamed holes, drilled holes, threads, tappers, taping, broaches, and bores.
CNC Lathe Machine is divided into four main parts:
Main Spindle
Guide Way
Chuck
Headstock
The main spindle is composed of a spindle drive system and spindle assembly. The CNC machine tool comes with some moving parts including chuck, gears, motors, etc. Moreover, the spindle assembly also includes the C-axis drive that is mainly used to position the material.
Guide way ensures the smooth cutting process by allowing the tool to move vertically and horizontally.
Attached to the main spindle, a chuck is used to tightly grip the object to be machined. Both the workpiece and chuck rotate with the help of the spindle.
The headstock, which houses the primary motor, is used to hold the main spindle, to which the chuck is attached.
CNC milling machines come with a range of cutting tools that move along one or more axes with the main purpose to remove extra material from the object. In the CNC milling machine process, the workpiece remains stationary while the machine rotates the cutting tools that form the material into the desired shape.
These machines are used in scores of industries including FMC manufacturing, oil drilling, automobile, shipping, aerospace, and precision engineering sectors.
The more advanced CNC milling machines, also known as CNC Machining Centers, are capable to perform along multiple axes. The precision and accuracy of these machines can be achieved with pallet changers, innovative coolant systems, automatic tool changers, and advanced software.
The CNC milling process starts with mounting the part to be machined on the top of the machine table. You can use a vice or fixture to hold the workpiece in place or you can clamp it directly on the table.
After that, the spindle (moving part) with the cutting tool is either positioned vertically or horizontally. In that setup, the tool can begin cutting and shaping operations at various X, Y, and Z positions on the workpiece. While doing so, the table may either fix, mount, or move the workpiece in a linear direction toward the spindle containing the cutting tool. As a result, the material will be removed to achieve the appropriate shape for the machined object.
These machines use high-power, focused laser beams to accurately cut, mark or engrave a material to produce desired shapes. The sophisticated design and operation of these machines perform the machining process without errors while creating small holes and complex shapes.
CNC laser cutting machines are mainly divided into three types.
CNC CO2 laser cutter
CNC crystal laser cutter
CNC fiber laser cutter
CNC CO2 laser cutters exhibit high power output capability and high efficiency, hence most commonly used to make custom shapes.
CNC crystal laser cutters show high laser power compared to CO2 laser cutters, thus allowing you to cut and shape thicker metal materials. In these cutters, the laser beam is made of crystals like neodymium-doped yttrium ortho-vanadate (Nd:YVO) or neodymium-doped yttrium aluminum garnet (Nd:YAG).
The CNC fiber cutters use a bank of diodes to produce a laser beam where fiber optic cable is used to eject the laser beam. In particular, for materials with a thickness of less than 5 mm, fiber laser cutters enable a quicker and more precise cutting process than CO2 laser cutters.
The CNC laser cutting process is slightly different from the conventional CNC machining process since it doesn’t involve direct contact with the workpiece, hence a thermal-based process. The laser cutting tool contains a laser head that houses a nozzle and laser cutting lens.
The nozzle projects a high-intensity laser beam on the component to be machined, melting and cutting the extra material from the component to form the required shape. Once the material is removed, the compressed gas is applied through the same nozzle to cool the lens and extract the vaporized metal from the workpiece.
The EDM, also known as spark machining or spark eroding, makes use of highly controlled electrical sparks to shape the material into the required form. Again, this is a non-traditional, precision machining method used to manipulate the material. The electric sparks produced in this process are near 8000º C to 12000º C. This process is typically employed for creating deep cuts and sharp corners that are otherwise impossible to achieve from the CNC milling and CNC turning process.
In this process, the machine is designed to emit an electrical discharge from the electrode wire that generates a great deal of heat and a component is positioned underneath the electrode wire (up to 21,000 degrees Fahrenheit). To generate the required shape, the material is melted or washed away with liquid.
EDM is mainly divided into three types:
Die sinking EDM
Wire EDM
Hole drilling EDM
In die-sinking EDM, graphite or copper electrodes are used while an electric spark is induced between the electrode and the part to be machined. It is the best method to produce parts with intricate cavities. Sometimes it’s difficult to create sharp internal corners with regular CNC machining. This is where Die sinking EDM comes in handy.
Wire EDM is best suited for creating extrusion dies. The mechanism is the same as die sinking, however, in wire EDM, fine electrically charged wire is used instead of a die. This charged wire also works as an electrode and is very thin, with a diameter ranging from 0.05mm to 0.35mm. This process is used for creating incredibly precise cuts.
Hole Drilling EDM, as the name suggests, is employed to create holes. The basic principle is the same as die sinking, however, the cut is created through a pulsing cylindrical electrode. This technique has been essential for the development of high-temperature turbine blades because it enables the production of extremely complex cooling channels inside the turbine blades.
Plasma cutting machines are another type of CNC machine used to precisely shape the workpiece. These machines use high-powered plasma (electronically-ionized gas) torch that is controlled and guided by the computer.
The plasma torch is gas-powered and comes with temperatures up to 50,000 degrees Fahrenheit. The high-temperature plasma strikes the material and instantly melts it, creating deep cuts with better control and accuracy. The materials that can be treated through plasma machines include copper, brass, aluminum, stainless steel, and steel. They all are electrically conductive materials which is the basic requirement for machining through plasma cutting machines.
Plasma-cutting systems offer fast cutting speeds and throughput along with a cheap cost per millimeter of material cut. These high-definition systems remove the need for secondary procedures on processed parts.
Furthermore, CNC plasma cutting is a remarkable option for applications in both large-scale enterprises and tiny hobbyist shops due to its fast speed and high accuracy.
The CNC Machine features 12 common components as below:
The part programming data is applied through input devices. The input devices are mainly divided into three common types:
This is the main part of the system, also known as the brain of the machine. The MCU is responsible for controlling all machine operations. Its main purpose is to decode the instructions provided by the programmer through the computer. The auxiliary control activities are all performed through this unit, like tool change, spindle on/off, and applying coolant.
It provides the axis speed order to the amplifier circuit powering the spindle mechanism. It receives feedback signals showing the position and speed of each drive axis.
A CNC machine tool comes with a sliding table and a spindle to control position and speed.
The machine can work around the X, Y, and Z axis which mainly handle the movement of the tables, while the Z axis is used to manage the spindle.
The Bed is composed of hard material like cast iron and is responsible for carrying all the machine weight, making sure each machine part stays in place when the machining operation is performed over the unit.
One of the main components is the headstock, where the workpiece to be machined is fixed. A headstock also houses the electric motor that powers the main spindle.
The tailstock quill is used to place the workpiece between the headstock and tailstock.
This part offers more grip to the workpiece during operations like turning, threading, and noodling.
The chuck is used to give space for fixing the tool and is mounted on the main spindle.
Pedal, also known as Footswitch, can open and close the chuck to grip the workpiece.
The display unit is a monitor that constantly shows important information, programs, and instructions on the screen.
The drive system of the CNC machine features an amplifier circuit, lead screw, and ball drive motors. The MCU plays a key role in providing the signals to the amplifier circuit. When the control signals are amplified, they turn on the drive motors.
A feedback system, also known as a measuring system, is equipped with transducers that are the sensors of the machine. These motion and position sensors continuously monitor the movement and location of the cutting tool, making sure the tool properly cuts as per the instructions given by the computer. This feedback system runs in a loop, continuously comparing the response signals with the reference signals and adjusting the tool movement and location accordingly.
The CNC machine comes with the following elements:
Program
Tape Reader
Mini-computer
Servo system
CNC machine tool
The keyboard is used to enter the program into the computer. The program is the code used to guide and control the machine's functions. The common CNC codes include: G code, N code, F code, XYZ code.
The tape reader serves as a storage device for the machine. It stores the code to be performed on the machine tools. The programmer can edit the code stored in this device.
This is also known as the machine control unit. It is mainly used to decode the program information and decide the spindle speed, start and stop the coolant, turn on/off the machine spindle, control the feed rate, and change the workpiece and a few other instructions to properly handle the tools as per requirements. Mini Computer exhibits diagnostic software that identifies the overall health of the machine and adjusts the machine's activities accordingly.
This system is directly connected with the feedback mechanism that receives the control signals and sets the output as per requirement.
Servo Motors
Feedback devices
Ball screws
This is the entire machine unit where the workpiece is machined and the final product is obtained after the machine operation.
The NC stands for numerical control. It is also an automatic manufacturing process but here the programs are in numeric, alphanumeric, or binary language. The NC machine has no computer and no feedback system and is less sophisticated than CNC machines. A special inserting device is used in NC machines that store the main program.
CNC machines guarantee the production of parts with high precision and accuracy, while on the other hand, NC machines don’t produce parts with fine quality.
In CNC machines operation parameters can be changed while NC machine doesn’t allow you to change parameters.
The NC machine doesn’t run in a continuous loop to produce parts with the same accuracy while the CNC machine can run repeatedly to produce scores of parts with similar specifications.
CNC machines are costly compared to NC machines and also the maintenance cost is very high.
Moreover, once the machine is set up and the program is fed into the CNC machine, a single person can perform a range of tasks. This is not the case with the NC machine. More labor is required to do each task, hence more labor cost and more time-consuming.
CNC systems are used in a range of industrial applications. A few common industries include:
Electrical discharge machining
Metal fabrication
Automotive
Agriculture
Electronics
Manufacturing
From higher flexibility and repeatability to consistent quality and increased productivity, these machines provide some key benefits over traditional machines.
There is no denying that CNC machines are the future of the manufacturing industry.
With the advancement in technology, companies are creating more space for automatic technology that involves minimum input and delivers maximum output.
CNC machines, no doubt, require more initial costs for setup and maintenance compared to the traditional manufacturing process. However, once the machine system is properly installed, it reduces human involvement and requires less time and cost to produce more parts with similar properties.
If you’re still using traditional methods to produce parts, it’s about time you consider CNC machining in your industry. The sooner you make a shift, the better.
That’s all for today. Hope you’ve enjoyed reading this article. I’d love to hear your valuable input regarding CNC machining. And if you have experienced this process before, share your insights in the section below. Until next time. Take Care.

Technology is changing fast. It’s constantly shifting and evolving. Tech is making our lives easier but it’s also creating new problems. It is changing the way humans behave and interact with one another. Technology is providing answers to things we never knew and solutions to problems we can’t solve on our own. There is a lot of innovation happening right now, especially in the field of engineering. Below are five technologies that are being innovated by engineers.
You’ve probably seen a video of a 3D printer or have heard about what they can do. 3D printing is changing fast and enabling us to do a lot with it. 3D printing software provides more tools and resources to print useful things for us. The medical industry has begun using 3D printed organs and other significant tools for the field of medicine. Engineers have taken 3D printing to a whole new level. It is getting to the point where we can 3D print anything we need. Think about it. Soon we will imagine things we want and simply print them.
Engineers are also helping innovate artificial intelligence (AI). With AI, there is no shortage of ways that our lives will change. We’re already experiencing it. Engineers were instrumental in creating AI chatbots that improve customer service and user experience . AI can analyze large sets of data. It can synthesize media using all the intelligence it has from the internet. AI is already solving problems that we used to deal with quickly. It is changing the way we live and think about the future. AI will continue to augment our lives in several ways, and engineers will facilitate this growth and, hopefully, steer it in the right direction.
One area of technology that will impact the way we live is our ability to urban farm and create more ways to capture carbon in the atmosphere. There are now examples of engineers creating living buildings, buildings that incorporate trees and other foliage into the design. There are also downtown farms. For example, there are now buildings that can be used for farming shellfish . These vertical buildings host aquariums of fish that are used for food. Engineers can work with environmentalists to create truly incredible infrastructure that could change the world. This is one area of innovation that shows promise for the future.
Optical engineering might seem like a consistent lane to be in, but this isn’t the case. Optical engineers have already innovated contacts, eyeglasses, telescopes, and more. This will only increase in the future. There are already plans for contact lenses that connect to the internet. Soon you will be able to see avatars, applications, and other online images simply with your contacts. You will be engaging with the internet on a whole new level. The optics are changing . Optical engineers will facilitate the shift from using phones to participating with the internet through virtual reality (VR).
There has been a lot of talk recently about the metaverse. This is what we are calling the world within technology we can engage with through goggles and headsets. Have you tried VR before? It used to be flawed but it’s getting better all the time. Engineers are making VR better and better all the time. It is getting more realistic and functional. There is also augmented reality, or AR. This is the technology that utilizes VR components with the tangible world. For example, remote medical surgeries are now a reality. With 5G internet, better AR, and engineering innovations, we can improve our way of life in many ways.
Engineering is also facilitating data , storage, and analysis. Engineers have created Cloud storage abilities and the capability to analyze large sets of data. Of course, AI will be able to analyze data a lot better than we will but storing data in the Cloud is how the AI will have it so organized. Data is easier to analyze when it is organized. Data has become one of the most valuable assets in modern business. When you have thoroughly analyzed data, you will have the ability to market to new customers, find new target demographics, and create both new products and services.
There is no shortage of ways that engineering is changing our world. Its relationship with technology continues to change. The way that we live is being augmented all the time. How will we think about these technologies in the future? With more and more innovation, the world will change around us. It’s an exciting perspective to look at the world through the engineer’s eyes.
, In recent years, additive manufacturing (AM) has become an increasingly popular topic in the aerospace industry. Additive manufacturing is the process of making three-dimensional objects from a digital file. It is also known as 3D printing.
In general, additive manufacturing builds objects by adding successive layers of material. This is in contrast to traditional manufacturing methods like machining or milling, which involve removing material from a block of metal or other material.
With technology evolving and becoming more widely adopted, additive manufacturing has transformed how aircraft are designed, built, and maintained.
This article will discuss some of the critical benefits of aerospace additive manufacturing.
Additive manufacturing provides greater design flexibility than traditional manufacturing methods. This is because AM enables the creation of parts with highly complex shapes and geometric structures that would be impossible to produce using subtractive processes like machining.
And this opens up new possibilities for engineers in aircraft design, leading to more innovative and efficient solutions.
For example, the most common type used in aerospace applications is called selective laser melting (SLM). SLM uses a laser to melt the metal powder into the desired shape. The advantage of SLM is that it can create complex aerospace components and shapes that would be difficult or impossible to create using traditional methods.
Here is an example of a complex design made through SLM.
Previously, products were made by assembling a wide range of individual parts. With additive manufacturing, products can be created using fewer individual parts since the designs are printed using a 3D printer at a time. This allows for more complex designs and saves time you’d otherwise spend in traditional assembling.
Aerospace manufacturers are always looking for ways to reduce manufacturing costs. One major way to achieve this is by adopting the aerospace additive manufacturing alternative. According to a survey conducted by Appendix, cost-effective manufacturing is among the most important benefits 3D printing offers to aerospace companies.
AM contributes to cost savings by creating complex designs with fewer steps and structural components. Traditional manufacturing methods waste a lot of material because it is impossible to use in the finished product. With 3D printing processes, only the amount of needed material is used, making it more efficient.
Also, additive manufacturing allows for greater customization, leading to reduced costs. For example, if a part needs to be made for a specific application, aerospace additive manufacturing can be used to create a part that is off the shelf. This saves the manufacturer from having to order custom parts from your aerospace suppliers , which can be expensive.
Additive manufacturing is generally much faster and more efficient than traditional manufacturing methods such as milling or casting. Besides the speed, it can produce parts with high accuracy and repeatability. This is because AM eliminates the need for tooling or molds, and parts can be produced layer by layer directly from digital 3D printing models with minimal material waste.
Storage requirements for aerospace equipment differ depending on the application. Some standard storage requirements include:
Temperature control: The equipment must be stored within a specific temperature range to prevent damage or malfunction.
Environmental protection: The equipment must be protected from harmful elements such as dust, moisture, or corrosives.
Storage requirements in the aerospace industry vary depending on the type of aircraft. However, aerospace industries are constantly looking for ways to reduce storage requirements, as storage space is a valuable commodity in this industry.
Additive manufacturing processes help minimize storage requirements by producing parts directly from a 3D printing model.
This reduces the required inventory since parts can be printed on demand instead of on storage carousels, as shown in the image below. Carousels are more common in traditional factories due to subtractive manufacturing methods, such as milling and turning, requiring much material and storage.
With aerospace additive manufacturing, parts are built up one layer at a time, so very little material is wasted. This means less storage is required to store the raw materials freeing up valuable space in factories.
Component weight is a critical factor in the aerospace industry. Every pound of weight eliminated from a single component allows for carrying additional payload or fuel, increasing the aircraft's range or performance.
In recent years, aerospace additive manufacturing has emerged as a promising technology for reducing the weight of aerospace components in the aerospace industry.
Additive manufacturing can create parts that are lighter and stronger than those that can be produced using traditional methods. This is because the additive manufacturing process does not require traditional cutting, drilling, or welding methods. As a result, less material is needed to produce a single component, which reduces its weight.
AM also allows for greater control over the process of manufacturing and chemical microstructures of materials. As a result, components can be designed with specific attributes like improved toughness or fatigue resistance. This reduces weight and decreases fuel consumption and emissions while improving performance and range simultaneously.
Finally, unlike traditional manufacturing, additive manufacturing enables general component design optimization, which helps with weight reduction. The result is lightweight structures. In traditional manufacturing methods, excess material must be added to compensate for errors and inaccuracies in the manufacturing process, resulting in heavier structures.
The aerospace industry is a critical part of our economy and our way of life. It produces and operates various aircraft, from commercial airliners to military aircraft. To keep up with the demanding needs of this industry, manufacturers are always looking for ways to improve their mechanical performance. One way that they are doing this is by using additive manufacturing technology.
Additive manufacturing has a transformative effect on the aerospace industry thanks to its many benefits, such as increased product complexity, reduced manufacturing cost, minimized storage requirements, and decreased weight of components.
As 3D printing technologies continue to evolve, more additive manufacturing applications will likely be found in aerospace, leading to an even more significant impact on the industry.
However, 3d printing technology is still relatively new, and there are not many standards in place. In addition, each manufacturer has its additive manufacturing processes and methods for creating parts, making it difficult to know if a part will meet the required specifications.
Hi readers! Hopefully, you are doing well and exploring something new. Every powerful machine has a secret weapon, a machine that few think about but is responsible for all speed, torque, and, relatively speaking, performance. That secret weapon is an incredibly engineered gearbox. Today, we discuss gearbox design.
Gearbox design and selection are amongst the most critical elements of mechanical engineering, as they involve how power will be best transferred between two rotating shafts. A gearbox changes speed and torque position from a power supply (usually a motor) to the required application. Gearboxes accomplish this through a series of different types of gears, in various configurations. Gearboxes allow machines to perform under various parasitic load conditions.
Gearboxes vary widely, from automotive experiences with gearboxes or transmissions, industrial equipment, wind turbines, and robotics. Each of these applications will have vastly different required gear configurations: spur gears, helical, bevel, worm or planetary gears. The selection of gears will vary due to the constraints of required gear ratio, torque, noise level, or efficient size in the application and lastly, the level of environment needed for the gearbox to be optimally integrated.
Designing a gearbox includes a number of considerations such as: material of the selected gears, efficiency, lubrication, heat dissipation, and the expected life span of the gearbox components. Key considerations of a gearbox design include gears, shafts, bearings, housing and controls. Careful consideration must be made so that losses in power can be minimised and that reliable operations are guaranteed with a long operational lifespan, with stresses that may be encountered in different environments.
Here, you will find the definition of the gearbox, its basic parts, types of gears used in it, types of gearboxes, objectives in gearbox design, steps to design a gearbox, and applications. Let’s unlock detailed guidance.
A gearbox takes power from an engine and sends it to another device, changing both speed and torque. A gearbox supplies the right RPM and torque levels for different types of vehicles and equipment. A gearbox changes speed and torque by % using different ratios. Gearboxes provide an efficient means of changing motion and torque, better overall performance, and improved fuel consumption. Gearboxes are found in many mechanical systems such as vehicles, industrial machines, and wind turbines.
Examining the pieces in a gearbox helps the designer and maintainer work on and troubleshoot problems with it. Every component is necessary for transferring power efficiently, without much wear on the machine itself. The basic parts of a gearbox are as follows:
Gears are the main component of a gearbox that change speed and torque. Gears transmit motion by engaging in pairs to convert the rotary motion of one shaft to another shaft with a designed gear ratio.
Spur Gears: connect parallel shafts, and are also one of the simpler ways to transmit power and motion.
Helical Gears: have angled teeth that allow for smooth, quiet operation.
Bevel Gears: used for shafts at right angles.
Worm Gears: best used for high rates of torque reduction, and are best for a compact design.
Depending on the function required by speed, load, and spatial limitations, each gear type equally serves a purpose. Design considerations will consider material strength, tooth geometry, and precision machining to achieve the best contact point with minimal backlash.
Shafts are the mechanical axis by which gears will turn, allowing for the transfer of torque and motion to other mechanical devices.
Input Shaft: the shaft that connects the source of power (e.g., engine, motor).
Countershaft: intermediate shaft that utilises gears but does not provide any motion; it is used to distribute torque.
Output Shaft: provides adjusted torque and speed to the driven mechanical device.
For the most part, shafts are made from alloy steel, and they must be engineered to support constant and changing forces that could cause them to bend, twist and weaken. It is extremely important to make sure all rotating parts are aligned and balanced, because misaligned or unbalanced parts can eventually damage the machine.
Bearings make possible the smooth and stable rotation of the shafts and minimize friction between moving pieces. Bearings assist in supporting both radial and axial loads, and specific gearbox designs may be used for specific applications.
Ball Bearings: Suitable for any light radial and axial loading.
Roller Bearings: Suitably rated for a heavy radial loading.
Tapered Bearings: Suitable for a combination of radial and axial loads.
Bearings will last indefinitely anything by protected from contamination and kept lubricated.
The housing provides the outside structure to the gearbox; it houses the internal components, provides structural support, and corrosion, allowing gears and shafts to be properly aligned.
The housing does the following:
Protect gears and bearings from dirt, debris, and moisture.
Act as a reservoir for lubricants.
Dissipate heat generated from mechanical operations.
Minimise the noise and vibration of operation.
Commonly used materials are cast iron for heavy-duty applications, and aluminium for lightweight machinery - it is essential that the housing be machined to an accuracy to stay within tolerances, and hold gears and shafts in position without misalignment.
Lubrication is critical for effective operation and longevity of components. Reducing friction, transferring heat, and preventing metal-on-metal contact is the lubricant's job.
The methods of lubrication are:
Splash Lubrication: A simple method, and one most used; gears dip into an oil bath.
Forced Lubrication: Pumps provide oil right to critical parts.
Mist Lubrication: Uses very fine oil mist, used for all high-speed gearboxes or other applications.
Different types of gears are used in gearboxes based on specific design parameters such as the required torque being transmitted, physical constraints such as available space, and noise and speed variation control parameters. Below is a list of the most common gears.
Spur gears have their teeth cut straight and are assembled on parallel shafts. The design is simple, it is easily produced, and it is very efficient. The drawback to spur gears is that they typically create the highest amount of noise and vibration, especially when run at higher speeds.
Helical gears have angled gears which engage gradually in a more controlled manner, which results in less noise and vibration and a smoother operation. Helical gears can be used to transmit higher loads, but introduce axial thrust, which should be accounted for. They are popular for high-speed or heavy-duty applications
These days, bevel gears are commonly built for shafts that connect at a 90° angle. Because bevel gears are built as cones, they permit the direction of power delivery to change. Bevel gears are commonly integrated into differential drives and gearboxes that form right angles.
They are made up of a worm (the screw) with a worm wheel. They can produce strong torque in small packages and are applied at high-speed reduction rates. Sliding contact in worm gears makes them less efficient and likely to produce heat.
The parts of a two-stage gear system are a sun gear, several orbiting planet gears and an outer ring gear. Because planetary gears have a high ratio of power to space, they are usually selected for use in many automotive, robotics and aerospace machines.

The core goal of gearbox design is to create an optimal system performance, reliability, cost, and operational efficiency. A good gearbox will provide an efficient means of transferring power to the driven machines while also tolerating in-use rigours and tribulations. Below are the key objectives in gearbox design:
The primary aim of any gearbox is to transmit power from the driving source, such as a walking beam pump or other motor devices, to the driven machinery as efficiently as possible. The proper torque and speed are needed for any given application. The designer must select the proper gear ratios, confirm or make the best provisions for the gearbox to accommodate the expected loads and provide leeway not to experience slippage or power loss while operating and without mechanical collapse.
In many applications, gearboxes are used for long periods and frequently in harsh environments. Gearboxes will need to be able to withstand wear, fatigue, thermal cycling and many other considerations over their entire service life. Choices in material selection, surface treatments, alignment, load distribution and reduced stress must be made to reduce failure rates.
Many applications, particularly in automotive, aerospace, and robotics, have strict size and weight restrictions. The gearbox must be designed to be as compact and light as possible, avoiding loss in strength or performance. This invokes a lot of thought into gear configuration and the housing that provides maximum power density.
Modern gearbox design incorporates reducing noise and vibration during operation, especially in consumer or comfort-sensitive locations. This has been done with components such as helical gears, precision machining, and the use of noise-reducing materials. A quieter gearbox usually means smoother mechanical operation and will experience less wear over time.
Gearboxes produce heat due to friction between moving parts. Effective design calls for adequate thermal management, from sufficient lubrication to heat dispersal in the gearbox housing, or even cooling systems. For component and performance efficiency in the long run, gearboxes should operate at sufficient and consistent temperature ranges.
The design begins with determining requirements around the application, such as input and output speed, torque quantities, and conditions of the application, such as ambient temperature, load cycles, or even environmental exposure. These requirements must be noted down as they will guide every decision that follows.
Designers consider the style of gear (spur, helical, bevel, etc.), but also the demands form the application. An important consideration will be material, considering strength and wear resistance. The designer has to calculate the specific gear ratio, consistent with speed and torque.
Shafts must be designed considering torsional resistance and bending resistance, while bearings take into consideration radial and axial loading. It is imperative to will also keep shafts aligned to ensure a service life without premature failure.
The house requires sufficient support for all internal components and contains sufficient provision for lubrication, cooling and maintenance. Structural rigidity and precision of internal layout are critical factors.
Selecting the right lubricant and delivery method will ensure a loss of friction and squash continued operation. Designing provisions for heat dissipation can be equally as important as avoiding thermal degradation.
The designer will conduct the final step on their design with fatigue check, checks for overload, and cap it with Finite Element Analysis (FEA). If prototypes are fabricated, they can also be subjected to real-world tests to validate that the design as-built meets their expectations and still meets their design objectives under conditions of use.
In the automotive world, gearboxes are found to be critical in both manual and automatic transmissions, and electric vehicle (EV) drive units, ensuring effective power delivery and optimization of the available fuel or battery energy.
In industrial machinery, gearboxes are present in conveyor systems, packaging/inspection machines, and material handling equipment, which provide the ability to modulate motor output to operational speed and torque requirements.
In aerospace, gearboxes are present in helicopter main and tail rotor drives (or engines) and in the position mechanism of satellites. These have a requirement for high precision and reliability to operate in harsh environments.
Gearboxes in wind turbine applications would be responsible for increasing the slow rotational speed of the rotor to a higher speed that is used by the generator, which improves the throughput of electric power production.
In marine applications, gearboxes can assist in directional propeller drives, anchor winches and thrusters, which all have requirements to withstand extreme loads and corrosion.
When a robot moves, gearboxes will typically be used to match the human-like control of joint movement with high accuracy and repeatability, especially in robotic arms and automated manufacturing systems.
Gearbox design is a vital part of modern mechanical engineering, making power transmission systems work. From automobiles to industrial applications, in aerospace, robotics, and renewable energy, gearboxes provide regulated, efficient torque and speed transmission. Moving from concept to reality, gearbox design starts a complex process that takes into account gear type, shaft geometry and alignment, bearing loads, gearbox housing structure, component lubrication, and thermal management.
A careful balance of durability against performance, size, cost, and noise is paramount. Modern gearbox design combines advanced materials and manufacturing techniques with computer-aided design (CAD), simulation technologies like finite element analysis (FEA), and successful design ideas have led to compact, reliable, and energy-efficient gearboxes. Industry is demanding compact size with more performance, so gearbox design will continue to innovate, integrate, and develop precision power for the foreseeable future. Because gearboxes need to be more compact and have more performance, they will need to be socially responsible while reducing the total cost of ownership. Gearboxes must continue to deliver, better and better, so our world can be powered with the most efficient designs with reliability built in.
