摘　　要：为了优化球轴承外圈沟道圆弧轨迹进给ELID(Electrolytic In-process dressing)磨削工艺参数,对6206深沟球轴承外圈开展了磨削正交试验。分析了摆动参数和磨削参数对套圈沟道轮廓度和表面粗糙度的影响规律。基于田口方法、灰色关联分析法和主成分分析法,将轮廓度和表面粗糙度转化为灰色关联度指标,对工艺参数进行了优化。结果表明:当摆动幅度为11°、摆动速度为4°/s、砂轮转速为19500 r/min、工件转速为50 r/min时,套圈沟道的轮廓度P_(t)为0.9651μm,表面粗糙度Ra为0.2582μm,磨削综合效果最优。To optimize the processing parameters in the ELID(Electrolytic In-process Dressing)grinding of ball bearing outer raceway with arc trajectory feed,the orthogonal grinding experiment of 6206 deep groove ball bearing outer ring was carried out.The influence of the swing and grinding parameters on the profile error and surface roughness of the raceway were investigated.With the Taguchi method,grey relational analysis and principal component analysis method,the optimization of processing parameters was performed by transforming the characteristics of profile error and surface roughness into grey relational grade.The experimental results show that the optimal grinding performance characteristics are a profile error of 0.9651μm and surface roughness of 0.2582μm,which can be achieved with a swing amplitude of 11°,swing angular velocity of 4°/s,wheel rotational speed of 19500 r/min,and workpiece rotational speed of 50 r/min.
