    Abstract:

    Aiming at the problem of repairing high-speed steel roll material, the control system of electrolytic grinding device for high-speed steel roll material was developed. Based on the machine tool of ordinary cylindrical grinder, S7200 SMART series PLC was used as the controller to control the cathode feed system, electrolyte supply system and processing system. The hardware, software and human-computer interaction design of the control system of electrolytic grinding device for high-speed steel roll material were carried out. The control system has modular functions such as automatic tool setting, fault detection and so on. A fuzzy controller PI dual-mode control method with correction factor was proposed for machining gap control, and the MATLAB/Simulink simulation model was established. The results show that the control method has ideal effect, strong robustness and it can adjust the controller gain parameters. The algorithm was programmed into PLC, the machining gap control process with small steady-state error, small overshoot, fast response, and good stability were realized. The pre experiment was carried out to explore the relationship between machining gap and temperature on machining current. The results show that the machining current decreases with the increase of machining gap and increases with the increase of temperature.
