提出了一种基于气液混合功能电极的电火花诱导烧蚀铣削加工方法，并针对Cr12与常规电火花铣削加工进行了对比试验，结果发现同等试验条件下，气液混合电火花诱导烧蚀铣削的电极体积损耗仅为1.1%，而常规电火花铣削的电极损耗为9%。针对此现象，从极间放电特性、电极端面覆盖层等因素出发，解释了电极损耗低的原因。最后，研究了不同加工参数下，气液混合烧蚀铣削电极相对损耗的工艺规律。

Put forward a new EDM method named spark-inducing combustion-milling machining based on function-electrode with gas-liquid mixture,and making the comparison experiment with the conventional ED-milling on machining of Cr12,found that the electrode volume loss rate of the spark-inducing combustion-milling machining is only 1.1%whereas the conventional ED-milling's is 9 %in the same test conditions. With regard to this phenomenon,the paper explains the reasons for the low electrode volume loss from the factor,such as the discharge characteristics between electrode and workpiece and the electrode surface covering layer. Finally,the rules of relative electrode wear rate of spark-inducing combustion-milling machining based on function-electrode with gas-liquid mixture under different processing parameters are studied.
