The lathe, probably one of the earliest machine tools, is one of the most versatile and widely used machine tool, so also known as mother machine tool. An engine lathe is the most basic and simplest form of the lathe. It is called so because in early lathes, power was obtained from engines. The job to be machined is held and rotated in a lathe chuck; a cutting tool is advanced which is stationary against the rotating job. Since the cutting tool material is harder than the work piece, so metal is easily removed from the job. Some of the common operations performed on a lathe are facing, turning, drilling, threading, knurling, and boring etc.
