Evaluating the influence of cutting parameters on part’s accuracy and grinding wheel’s wear in grinding profile for ball bearing’s inner ring groove

Abstract

This paper presents some research results to determine the impact of grinding parameters on grinding wheel's wear and part's accuracy in grinding profile for ball bearing's inner ring groove. Firstly, the distribution diagrams of part's tolerance zone and grinding wheel's wear at different cutting conditions has been used to determine important outputs in the profile grinding process for the inner ring groove of the ball bearing. Based on that, the experimental regression functions that express the dependencies of the important outputs (grindstone wear Hzi, surface roughness Ra, oval Op) on the technical parameters (normal feed rate Fn, speed of part Vp, depth of cutting t and the number of part in a grinding cycle Np) are determined by the least squares experimental planning method. From those mathematical functions, the effect of grinding parameters on the grinding wheel's wear and part's accuracy in profile grinding for the inner ring groove is valuated.
