Machining is a process in which a material often metal is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing , [1] in distinction from processes of controlled material addition, which are known as additive manufacturing. Exactly what the "controlled" part of the definition implies can vary, but it almost always implies the use of machine tools in addition to just power tools and hand tools.

After reading this article you will learn about:- 1. Meaning of Metal Cutting 2. History of Metal Cutting 3. Types of Cutting Processes 4.

Hundreds of varieties of metal machine tools, ranging in size from small machines mounted on workbenches to huge production machines weighing several hundred tons, are used in modern industry. They retain the basic characteristics of their 19th- and early 20th-century ancestors and are still classed as one of the following: 1 turning machines lathes and boring mills , 2 shapers and planers, 3 drilling machines, 4 milling machines, 5 grinding machines, 6 power saws, and 7 presses. The engine lathe , as the horizontal metal-turning machine is commonly called, is the most important of all the machine tools. It is usually considered the father of all other machine tools because many of its fundamental mechanical elements are incorporated into the design of other machine tools. The engine lathe is a basic machine tool that can be used for a variety of turning, facing, and drilling operations.
