电火花线切割机床在加工变厚度工件时，工件厚度变化处易出现加工条纹，影响加工质量和加工效率，而根据不同厚度的工件采用不同的加工参数，可明显改善加工质量和效率。利用往复走丝电火花线切割机床进行不同厚度工件的加工试验研究，采用正交试验法进行规划，并对试验结果进行分析，研究其加工规律，分析得到加工变厚度工件的理想参数，从而实现电火花线切割加工变厚度工件时始终保持较高的加工效率及一致的表面质量。

When workpiece with variable thickness is machined by the wire-cut electrical-discharge machines,machining strips appears apparently as the thickness of workpiece changes,which influences the quality and efficiency of the processing sharply. To improve the processing efficiency and surface quality,different machining parameters are adopted according to the different thickness of the workpiece. Experimental studies focused on the variable thickness processing are carried out by the reciprocating traveling WEDM. In addition ,the orthogonal experimental design was adopted to program the experiments and research the machining rules. Ultimately ,the ideal machining parameters depended on the thickness of the workpiece are discovered by analyzing the rules ,which guaranteed higher machining efficiency and better uniformity of the surface quality when machining the workpiece has variable thickness by WEDM.
