摘　　要：通过对超大厚度电火花线切割工艺参数影响因素进行分析,利用正交试验的方法,研究了加工电流、脉冲宽度、占空比、进给速度等电参数对加工速度的影响规律,确定最佳的工艺参数设置条件。并在此基础上,应用多元正交回归分析方法建立可靠的回归方程,方便对试验结果进行预测和优化。When the WEDM cut the super-large thickness workpiece, the electrical parameters play a important role in the machining rate. The orthogonal test was used to study the influence of the electrical parameters including current processing, pulse duration, duty-cycle and feed rate. The best qualification of optimal electrical parameters of WEDM were gotten, and the reliable equation was gotten through the orthogonal regression analyse.
