Compared with a conventional machine tool, the numerical control machine tool has a numerical control system (program control system) which can realize an automated machining process according to a previously programmed program, but the conventional machine tool does not have this feature. The comprehensive use of the numerical control machine tool can reduce the labor intensity of workers, reduce the tooling and labor cost, shorten the trial production period and the production period of new products, and is favorable for enterprises to make quick response to market demands. In addition, with the development of science and technology, the informatization technology is continuously improved, and FMC (flexible manufacturing unit), FMS (flexible manufacturing system) and CIMS (computer integrated manufacturing system) technologies are more and more widely applied.
