中文摘要：

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．

英文摘要：

This study investigated the optimization of mist-jetting electrical discharge machining （ED-mill-ing） process. Firstly, experiments were carried out to choose the ranges of parameters such as to/Toff, milling layer depth（MLD）and tool electrode wall thickness for optimization. Then a set of experiments was designed based on Taguehi method to investigate these effects of main machining parameters on the materi-al removal rate（MRR） and tool wear ratio（TWR）. The analysis of variance（ANVOA） results show that.
