Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams. Machining can also be performed on an existing part, such as a casting or forging. Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites. Since the advent of new technologies such as, CNC center machines, electrical discharge machining, electrochemical machining, electron beam machining, photochemical machining, ultrasonic machining, etc., the conventional machining is used to differentiate from these modern technologies. Most beginners tend to be a little intimidated when they see a machine tool in operation for the first time. As you go along in this course, you will find that machine tools are very friendly, logical and easy to understand with proper instructions. Machining can be a business, a hobby, or both. The modern machining nowadays is carried out by Computer Numerical Control (CNC), in which computers are used to control the movement and operation of the cutting machines. According to history, the advance in the accuracy of machine tools can be traced to Henry Maudslay when he established the manufacture and use of master plane gages in his work shop. With the accuracy creation of master plane gages, all critical components of machine tools could then be developed to the desired improvement. The first machine tools offered commercially available were constructed by Matthew Murray in England around 1800.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
