This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements. It automatically processes parts according to the shape and size required by the drawings. CNC machine tools effectively solve the problem of processing complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.
