Machining is done so as to make a piece of raw material cut into a desired final shape and size by a controlled material- removeal process. Much of modern-day machining is carried out by Computer Numerical Control (CNC) machine, in which computers are used to control the movement and operation of the mills, lathes and other cutting machines.
