Production is controlled and allocated by a puterized controller. The controller uses motors to drive each axis of a machine tool and actually regulates the direction, speed, and length of time each motor rotates. A programmed path is loaded into the machine39。s puter by the operator and then executed. The program consists of numeric point data in conjunction with specialized machine control mands and function codes.Principle of NC machine tool 《 NC Technology 》 E- mail: The work process of NC《 NC Technology 》 E- mail: Basic ponents of CNC machine tool《 NC Technology 》 E- mail: The evolution of NC The principle of NC manufacturing has been evolving since the Industrial Revolution.
