摘　　要：在电火花成型加工中以紫铜为电极加工不锈钢(1Cr11Ni2W2MoV)工件,为了缩短加工时间、提高工件表面质量,对加工过程中放电幅、休止幅和低压电流3个主要脉冲电源参数对工件表面粗糙度和加工时间的影响规律进行了研究,通过对实验数据的分析,结合正交试验和田口算法对试验结果进行分析,初步确定这3个要素的影响程度,然后采用极差分析方法对正交结果进一步处理,得出各要素对试验的影响程度。发现极差分析结果与田口算法得出的结论一致,经过分析得出最优的参数组合。最后通过实验进行验证而确认了田口法适用于电火花成型加工。In the EDM machining,copper is used as the electrode to process stainless steel(1Cr11Ni2W2MoV)workpieces.In order to reduce the machining time and improve the surface quality of the workpiece,the effects of discharge amplitude,rest amplitude and low voltage current on the surface roughness and machining time of the workpiece are studied.Through the analysis of experimental data,the test results are analyzed in combination with orthogonal experiment and Taguchi algorithm,and the degree of influence of these three elements on it is initially determined,And then use the range analysis method to further process the orthogonal results to obtain the degree of influence of each element on the experiment.It is found that the results of the range analysis are consistent with the conclusions drawn by Taguchi,and the optimal parameter combination is obtained after analysis.Finally,it is verified through experiments that Taguchi method is suitable for EDM.
