摘　　要：基于田口法考查了电火花加工在煤油、空气状态下的临界放电间隙及主要加工电参数(峰值电流、放电电压、脉冲宽度)的变化规律和影响顺序,为进一步理解电火花加工机理提供了实验基础。The Taguchi method was used to analyze the critical discharge gap under the dielectric of liquid and air. The parameters were peak current,open-circuit voltage and pulse-on duration. Then the parameter was determined by Taguchi method and the reasons were deduced. These studies will be beneficial to further applications.
