摘要：  采用单因素实验对适合喷雾电火花铣削加工的脉宽/脉间比、层进给量及电极壁厚等参数的优化范围进行了选择；基于田口方法进行了喷雾电火花铣削加工的实验设计,根据实验结果建立了材料去除率的经验公式.实验及方差分析结果表明，材料去除率受脉宽/脉间比的影响最显著；采用优化后的加工参数大大提高了材料去除率，实现了喷雾电火花铣削的高效加工.

Abstract: This study investigated the optimization of mistjetting electrical discharge machining (EDmilling) process. Firstly, experiments were carried out to choose the ranges of parameters such as ton/toff, milling layer depth（MLD）and tool electrode wall thickness for optimization. Then a set of experiments was designed based on Taguchi method to investigate these effects of main machining parameters on the material removal rate(MRR) and tool wear ratio(TWR). The analysis of variance(ANVOA) results show that the ton/toff has a dominate influence on the MRR and the influences of the machining parameters on the TWR are negligible. A higher MRR is obtained through the optimized parameters. Key words：
