摘要
以Cr12MoV为工件材料,研究电火花加工中脉冲宽度、脉冲间隔和放电电流等工艺参数对工艺指标材料去除率、电极损耗率和表面粗糙度的影响。为了优化工艺指标,将相关分析方法与Taguchi方法相结合,通过灰相关度系数值决定优化的工艺参数,最后利用方差分析,确定放电电流对工艺指标的最大影响。
Electrical discharge machining of Crl2MoV is studied. Influence of pulse-on time, pulse-off time and discharge current are investigated for material removal rate and electrode wear ratio and surface roughness. In order to optimization process responses, the grey relational analysis based Taguchi method is used. The grey relational grade is used to determine the optimal process parameters. Analysis of variance shows that discharge current is the most significant parameter for process reponses.
