摘　　要：利用电火花线切割加工Cr12MoV钢这种重要的模具材料时,其材料去除率和表面粗糙度是衡量加工质量的重要性能指标。故通过正交实验,利用极差分析和方差分析探索电火花线切割电参数(脉宽时间、脉间时间、峰值电流和间隙电压)对其性能指标的影响,并应用灰关联分析法,合理选择参数,解决参数组合的优化问题。结果表明,利用经优化后的参数组合加工实验试件,达到了预期的加工效果,这一方法可为实际生产中利用电火花线切割加工Cr12MoV钢提供理论指导。While using WEDM processing Cr12MoV steel of the most important mould material,its material removal rate and surface roughness is an important performance index to measure the processing quality. Through orthogonal experiment,researches the influence of the electrical parameters（pulse-on time,pulse-off time,peak current and gap voltage） on its performance index,and through the grey relation analysis,choosing the parameters reasonably,to solve the problem of optimization of parameters combination. The results show that,using parameters which are optimized by processing the testpiece,getting desired effect. This method provides theoretical guidance for WEDM processing Cr12MoV in actual production.
