- Abstract
Aiming at the human machine interaction mode outmoded of traditional electric spark diamond grinding wheel trimming machine pulse power supply, the power source main vibration pulse anti-interference ability is weak, low discharge efficiency and severe parasitic inductance, an electric spark pulse power supply was designed. Using Mitsubishi PLC as the system main controller, STC8A8K64S4A12 single-chip microcomputer and EPM570T100C5N CPLD programmable logic device were selected as a pulse master chip. At the same time, the hardware and software of the electric spark pulse power supply were designed. A diamond grinding wheel trimming prototype was produced. Based on the stone ink wheel, the discharge processing tests were performed by the diamond grinding wheel as machining workpieces. At the same time, the designed power supply processing performance was checked, it had a process comparison test with traditional electric spark diamond grinding wheel trimming machine. The results show that the designed pulse power control method is simple, the parameter setting is convenient, the discharge waveform anti-interference ability is strong, it is not easy to distortion, the discharge efficiency is high, the surface quality of the processed diamond grinding wheel is high, and the formation surface particle is high integrated.
