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.
What is CNC milling, and what are its uses?
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 m ...
The article will cover essential aspects of fluid statics and pressure forces applied to the fluid. The article will start with the absolute pressure gauge and the variation of pressure with depth in different gravitational field manometers and barometers, respectively. Then I will explain the forces that deal with fluids, such as hydrostatic force, buoyant force, etc. So, dear friends, without wasting any time, let’s start.
Pressure
The definition of pressure according to fluid mechanics is as follows:
Pressure is the normal force applied by a fluid per unit area.
Unit of Pressure
The units of pressure Pascal is too small to deal with in practical cases. For instance,
Kilopascal: 1kPa=103Pa
Mega Pascal: 1MPa=106Pa
The three common pressure units used are standard atmosphere ba ...
Hi, my friends and welcome back. I am happy to meet you again with a new tutorial of our PLC ladder logic programming series tutorials. Today we will complete what we started the last tutorial on the Elevator control project. We have a bunch of duties to complete together today. So let’s save time and jump into work immediately.
Project description:
Figure one shows the details that might help me describe the project between our hands. We have an elevator car that travels up and down and can stop on one of four floors based on the passengers’ requests. We have 6 push buttons on the wall next to the elevator door that can send requests to call the elevator. In addition, there is a control panel inside the elevator cabinet in which there are push buttons to request stations to reach floors ...
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?
What is Custom Metal 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 req ...
Hi Everyone! How are you doing, my friends? Today I bring a crucial topic for PLC programmers, technicians and engineers. We have been working together for a long time using ladder logic programming. We have completed together dozens of projects from real life and industry. One day I was thinking about what we have done in this series of ladder logic programming, and I came across that I missed talking about one essential topic ever. You know what? It’s the PLC troubleshooting and online debugging! After writing a ladder logic program for the project, you can imagine it should operate from the download moment 24/7. As usual, any system goes faulty one day. So we need to go through this matter, showing you how to find our PLC faults, troubleshoot, and go online with the PLC to figure out th ...
Believing in the essence of timers in ladder logic programming, we come today with a new tutorial in which we are going to show you all about timers, the types of timers, what’s inside timers’ block of parameters, variables, and bits. In addition, techniques for using timers will be explored, and for sure, we are going to practice what we learn using the simulator. So let’s get started with our tutorial.
Timers in ladder logic programming
Guys, this is not the first time we’ve talked about timers. However, this time we are going to look into timers deeply and use the glasses of practical approach. So figure 1 shows the most important types of timers in ladder logic from left to right: the on-delay, off-delay, and retentive timers. There are differences in functionality. However, they all ...
Hello, my friends and welcome back with one new tutorial of our ladder logic programming series. Today I am bringing one exciting project which you can see everywhere, in your home, work, and public places, which is an elevator. We will design a solution using plc ladder logic programming, which drives the elevator. Our elevator is composed of 4 floors and has all capabilities of large-scale elevators. So let’s get started and save time and jump into our tutorial.
Elevator Project
As you can see, Everyone figure 1 depicts the complete scene of the project and tells that the elevator we will manage has four floors to visit. On the first floor, there is only one outer request to call the car from any floor above, i.e. from floor 2, floor 3, or floor 4. While on the second floor, there are ...
It is one of the most critical topics whenever. It is related to the resistance a fluid faces in motion. A fluid exerts a force on a body in a different direction. Now the main question is, what is drag? And what do we know about it?
What is Drag?
The definition of drag is as follows:
The force exerted on a flowing fluid in the direction of fluid flow is called drag.
Some of the essential key points related to the drag are as follows:
In order to elaborate on the drag force through an example. The body is attached to calibrated spring, and it is used to measure the displacement in the direction of flow.
The drag balances are one of those devices that are commonly used to measure the drag force.
It is not wrong to say that the drag force is much similar to the frictional force. ...
Hello Friends. I hope you are doing great. In this article, I will cover the nature of flow responsible for the changes in density. The nature of flows responsible for density change is known as compressible flows.
Fluid dynamics and thermodynamics combine for the theory of compressible flows. The compressible flow creates a relationship with the ideal gas. First, I will explain the stagnation state, speed of sound, and then the Mach number. This all comes under compressible flows. Then there come the static and stagnation fluid properties, shock waves, and variation of fluid properties in the case of regular and oblique waves. All of these are discussed in this article. So without wasting any time, let us start with the Stagnation property.
Stagnation Property
The definition of the sta ...
Hello friend. In this article, I will cover essential points related to fluid kinematics, i.e., what fluid kinematics is and how the motion of the fluids can be explained without describing the forces acting on them. Further, I will explain Lagrangian and Euler about the motion of fluid and a lot more. So buckle up, and let’s start.
What is Fluid kinematics?
The definition of fluid kinematics is as follows:
Fluid kinematics is related to fluid motion without considering the forces responsible for the motion.
The following are some essential key points related to fluid kinematics:
The nature of fluid motion is categorized into two types: Lagrangian Euler.
I will extensively explain both types in upcoming topics.
The acceleration, velocity ...
