Knee milling machines are fundamental to many engineering and fab shop floors. To appreciate their usefulness, first define them by their unique Z-axis architecture. Unlike a bed mill where the head travels over a fixed bed, a knee mill is a vertical mill where the workpiece table is attached to a large cast iron knee.
The knee moves up and down along a column, exposing the X-axis (left/right), Y-axis (forward/back) from the horizontal table on top of the knee, and the spindle with the cutting tool hanging down from above. The spindle is held in a quill that can move up and down independent of the knee mill’s Z-axis. The knee is the primary vertical adjustment, but the quill carries out the detailed vertical motion of the cutting tooling. This mechanical layout gives knee milling machines ...
Hey Friends! Hope you are doing well. Today, I am going to give you a detailed Introduction to Arduino Pro Mini. It's a microcontroller board developed by Arduino.cc and is based on the Atmega328 microcontroller.
Arduino Pro Mini is quite similar to Arduino UNO in overall functionality however the main difference lies in its size and built-in programmer. Arduino Pro Mini is very small in size & it lacks a built-in programmer & USB Port. Arduino Uno comes with two onboard voltage regulators (i.e. 5V and 3.3V) while Arduino Pro Mini comes with a single voltage regulator.
There are two versions of Arduino Pro Mini available, first one operates at 5V & runs at 16MHz while the second one is of 3.3V runs at 8MHz.
Arduino boards are mainly u ...
Hello everyone I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge on Introduction to TL494. It supports all of the functions that are necessary for the Pulse Width Modulation (PWM) control circuits. Power supply control is the basic purpose of the TL494 device. It has an output control circuit, a flipflop, dead time comparator, two different error amplifiers, 5V reference voltage, oscillator and a PWM comparator. TL 494 operates properly between the frequency of 1kHz to 300kHz.
The Dead Time Comparator (DTC) provides around 5% of dead time. Both of the error amplifiers display a common-mode voltage from -0.3V to (Vcc-2)V. If we provide a sawtooth wave at the CT terminal and terminate RT to the referenc ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share Best Sites to Get Engineering Homework done. Within modern society, time is a precious resource, and it seems that with every passing day there is less of it available. It couldn’t be more accurate than for the world of Academia. Many modern students face the dilemma of time management, where they have too much work and too little time to do it in. Within the field of Engineering, students find that they are overwhelmed with the workload. They become stressed, overworked and can even burn out. This, of course, results in lower grades and ultimately affecting their career paths.
However, while the world is getting busier, it also invented services that assist st ...
Hi readers! Hopefully, you are having a great day and exploring something new and advanced. In the competition to miniaturize electronics and increase performance, the smallest holes in your PCB, micro vias, are carrying the biggest load. Today, the topic of our discourse is micro via technology and its use for miniaturization in modern PCBs.
In this electronic revolution, the thirst for miniaturization, speed, and power will remain insatiable. Today's electronics scale down, complexity increases daily, from smartphones to wearable devices, from aerospace equipment to medical implants. Behind this miniaturization process is a key breakthrough in printed circuit board (PCB) technology, Microvia Technology.
Microvias are extremely small vias, usually under 150 microns in diameter, for ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to tweet from Raspberry pi. We also discussed some methods used by the tweepy library to perform some API calls in our project. We will learn how to print from a Raspberry pi in this lesson.
Let us get started
There are several benefits of having a print server. Print servers may link numerous computers to one or multiple printers, either physically or wirelessly, allowing you to access the printer with various devices and send print instructions from all the other connected computers.
It is not easy to print from an Android smartphone to a cabled printer; however, a printer server makes it simple. A print server is useful in small workpl ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at General Overview of Cisco CCNA Routing and Switching Certification. For communication to be enhanced, a proper network needs to be ensured at all times. There are many professionals who help in configuring your network in order to guarantee a hassle-free experience when communicating. This includes making the Internet accessible and also making sure that there are no interruptions in the network.A professional in this field needs to have mastery in two major aspects if to speak about boosting networks. These aspects are routing and switching.
Switching encompasses the connection of various devices to one network and in most instances, within the same buildin ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 74HC245. 74HC 245 is a eight (8) bit transceiver. It has three (3) output states. 74HC-245 is designed for a-synchronous transfer of data between different data buses. The external timing requirement can be reduced by the implementation of control function. You should also have a look at Introduction to 74HC595.
There are two internal amplifiers in 74HS 245. They are named as A and B. Data is transferred from A amplifier to B amplifier and vice versa. Hence two way communication is done in 74HC-245. This communication depends upon the logic level on the direction control input (DIR). Out enable pin (OE) is used to ...
Hi Fellas! I hope you all are having fun. Today, we will have a detailed overview of Flexible PCB. We will also understand why we need to use Flex PCB? What are its advantages & disadvantage? What kind of material is used? and How to manufacture flexible PCB? etc. Flexible PCB is the most advanced type of PCB, thus quite expensive and is normally used in industrial electronic products.
I'll try to explain everything related to flexible PCB so that you could get a clear idea of what is this about and what makes it stand out from other PCB boards? Let's dive in and explore the properties of flexible PCB one by one:
What is Flexible PCB?
Initially, PCBs were designed using hard substrate materials and th ...
Hello Friends! I hope you all are doing well. Today, I am going to share with you a very basic and detailed tutorial on What is Chemistry? We will also discuss Chemistry types, popular Chemistry books, famous Chemists and their great inventions in the field of Chemistry etc. When you hear the word Chemistry, you may think, it is only concerned to the study of chemicals, dangerous substances etc. But let me surprise you, Chemistry is also known as the Central Science means it is the insight study of almost everything around us. I just remembered very comprehensive Chemistry definition by American Chemical Society, “Everything you touch, see, smell and hear involves Chemistry and chemicals”.
Scientist divided Physical sciences in 5 major discipline ...
