Numerical control technology, also known as CNC (Computerized Digital Control), aims to realize digital program control through computers. This technology uses a computer to perform the logical control functions of the equipment motion trajectory and the peripheral equipment operation sequence according to the pre-stored control program. Because the computer is used to replace the original numerical control device composed of hardware logic circuits, various control functions such as storage, processing, calculation and logical judgment of input operation instructions can be realized through computer software, and the micro-instructions generated by processing are transmitted to the servo drive device to drive the motor or hydraulic actuator to drive the equipment to run.
