Optimization of Processing Parameters in ELID Grinding of Ball Bearing Outer Raceway with Arc Trajectory Feed
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 0.965 1 μm and surface roughness of 0.258 2 μm,which can be achieved with a swing amplitude of 11°,swing angular velocity of 4°/s,wheel rotational speed of 19 500 r/min,and workpiece rotational speed of 50 r/min.
