CNC system is a numerical control system which uses computer to control machining function. According to the control program stored in computer memory, the CNC system of large-scale CNC machining performs some or all numerical control functions, and is equipped with interface circuit and servo drive device. CNC system consists of NC program, input device, output device, CNC device, PLC, spindle drive device and feed (servo) drive device (including detection device).
The core of CNC system is CNC device. Because of the use of computer, the system has software function, and PLC is used to replace the traditional logic control device of machine tools, which makes the system more compact, flexible, universal, reliable, easy to realize complex CNC functions, easy to use and maintain, and has the function of connecting with the upper computer and remote communication.
