Generation process of cutting edge distribution on grinding wheel

Abstract

In this study, the effect of the depth–of–cut and spark–out in dressing on the generation of the cutting edge distribution was examined based on the peak distribution of the working surface profile and its change behavior. As a result, the following have been found out: the reduction of the depth–of–cut to be lower than the critical value suppresses the shedding of the grain and increases the density of the cutting edge. Appropriate amount of spark–out removes the damaged grains and increases the density of the cutting edge, and then improves the finished surface roughness. However, excessive spark–out makes loading easy to occur, and makes the finished surface roughness worse.
