Numerical control technology is also called computer numerical control technology (CNC, Computerized Numerical Control), which is a technology that uses a computer to realize digital program control.
This technology uses the computer to execute the sequential logic control function of the movement track of the equipment and the operation of the peripherals according to the control program stored in advance.
Because the computer is used to replace the numerical control device originally composed of hardware logic circuits, the realization of various control functions such as storage, processing, operation, and logical judgment of input operation instructions can be completed by computer software, and the micro-instructions generated by processing are transmitted to the The servo drive device drives the motor or hydraulic actuator to drive the equipment to run.
