Numerical control technology

Numerical control technology is also called computer numerical control CNC ）It is a technology of digital program control by computer. This technique uses a computer to perform the control function of the equipment according to the control program stored in advance. Because the computer is used to replace the numerical control device composed of hardware logic circuit, the realization of various control functions such as input data storage, processing, calculation and logical judgment can be completed by computer software. Numerical control technology is an important part of manufacturing informatization.
