The intelligent control unit receives signals from the speed setting unit and the displacement detection control unit, makes corresponding decisions autonomously according to the input signals, and transmits the feed speed parameters to the speed command unit; S2: The speed command unit transmits the speed command signal to the motion controller, which implements closed-loop control of motor 2 and semi-closed-loop control of the feed system. S3: The displacement sensor transmits the detected position / distance signal to the displacement detection control unit, and the theoretical position / distance signal from the PC is transmitted to the displacement detection control unit, which processes the signal and transmits it to the feed system intelligent control unit; S4: The main motion system control unit performs intelligent optimization processing on the process parameters by recording the material processing process parameters in the established database.
