Analysis of Surfaces Characteristics Stability in Grinding Process (original) (raw)

Advances in Mechanical Engineering and Mechanics, 2019

Abstract

In this work, we investigate the effect of the grinding wheel morphology at grain scale on the stochastic aspects of the process. This morphology was controlled through dressing conditions in order to optimize the ground surface characteristics while minimizing their variance. It has been found that under the same grinding conditions, the surface characteristics and their dispersion vary significantly according to the dressing parameters. For the case of the grinding wheel (95A46M6V) dressed by a single-point diamond, a good choice of dressing conditions allows to reduce the roughness from 2 to 0.76 µm with a scatter less than 10% and to increase the hardening from 220Hv with a scattering of 40% to 382Hv with a dispersion of 23%.
