摘　　要：重点分析ELID磨削过程中砂轮表面氧化膜的作用机理,得出EILD磨削加工过程中的电压电流值大小可以表征氧化膜状态.在ELID磨削工艺实验基础上,分析了氧化膜状态主动控制下的ELID磨削控制策略,并将模糊控制技术应用于ELID磨削系统上,针对ELID磨削过程的非线性和时变性,通过MATLAB仿真制定了模糊控制规则,并确定了模糊控制的基本参数,以此设计出ELID智能加工系统的模糊控制器,最终开发出了基于模糊控制的ELID磨削智能加工系统,实现了高效率、超精密ELID磨削智能加工.This paper focuses on the mechanism of grinding wheel surface oxide film in the ELID grinding process,it concludes that value of voltage and current in the process of grinding can characterize oxide film.On the basis of ELID grinding experiments,it analyzes the ELID grinding control strategy of oxide film and applies the fuzzy control technique to the ELID grinding system to determine the basic parameters of fuzzy control.According to the nonlinear and time-varying of ELID grinding process,it establishes fuzzy control rules by MATLAB simulation and designs the fuzzy controller of ELID intelligent processing system which lays a foundation of intelligent process control system.
