Numerical control technology is integrated what technology of computer technology, microelectronics technology, automation technology, electric power electron and contemporary machinery make a technology wait is flexible production automation technology. The numerical control technology that this chapter place narrates, it is to point to the numerical control technology that uses at the machine tool, the current situation that it reflected technology of contemporary numerical control to develop, incline to reachs the main content that include, because length place is restricted, this chapter will not include numerical control technology is all content, and be confined to: 1) the computer number control equipment that used advanced microprocessor (ComputerizedNumericalControl -- CNC) . 2) apply at the machine tool can make up Cheng controller (ProgrammableLogicController -- PLC) . 3) those who apply at the machine tool, the communication that used power electronic parts and advanced control theory and dc servo, include actuating device of machine tool feed, main shaft actuating device, communication and dc feed electric machinery and main shaft electric machinery and corresponding feedback component among them. 4) the to program of numerical control machine tool, basically be the to program that points to treatment component, and the systematic to program that does not include numerical control system and the process designing technology that can invent Cheng controller.
