The computer numerical control device of feeder machine is the core of the numerical control machine tool, usually consists of hardware and software. The hardware is mainly composed of an operator, a controller, a memory, an input interface, and an output interface. The software mainly refers to the main control system software, such as data processing and control and sequential logic control.
The function of the computer numerical control device is to accept externally input programs and instructions. After decoding, storage and computer processing, corresponding pulses are output to drive the servo system to control the motion of the machine tool. In addition, command signals output to the assist control device complete various assist control functions. The basic workflow of computer numerical control devices is input, decoding, position control, I/O processing, display and diagnosis.
