Illustrate the Explanation of NC Machine Tools?

Numerical control (NC) is considered to be an improved control for machine tools that provides higher productivity. Today industry demands faster production in harder and tougher materials to unprecedented tolerances. Conventional machine tools these demands and the answer to the problem has been found in what is called the Numerical Control of machine tools. Numeric Control is a method of controlling of motion of machine tools components by means of coded instruction in the form of numbers on tapes or punch cards.

The Program is recorded on a tape or punch card. Punched tape is then directed to the machine control unit (M.C.V). Which convert the information in to electrical signals and sends them to electrically controlled servo system which are used to drive the slides of machine tools at the appropriate speed and directions .Numerical Control has caused a virtual revolution in the discrete metal parts manufacturing industry. The success of N.C has led to a number of extensions of numerical control concepts and technology.
