摘要

This paper describes based on the STM32 the dynamic control systems of the ELID grinding oxide film growth process. The system's structure mainly includes the STM32 controller, DC pulse power source, VMOS circuit and optically coupled isolation circuit. The STM32 controller receives the oxide film thickness value from the host computer. According to the oxide film thickness values, the STM32 controller calls the process library automatically. Based on the process library parameters, the timer outputs the PWM square wave which the frequency and duty cycle can be adjusted, and the serial port output message controled DC power output. The PWM square wave is used to control the on-off of the VMOS circuit, which can be used as the DC converter of the programmable DC power supply, and generates high frequency pulse voltage to control the growth rate of the electrolyte. Finally, the experimental results show that DC pulse power supply output values and the expected output value are consistent.
