摘要
Understanding grit wear and the consequent material removal mechanisms is of critical importance to ele-vating the performance of dry grinding. This study conducts a single-grit grinding analysis on the grit wear-induced thermomechanical variations and resultant surface integrity for ceramic alumina and CBN grits. The results reveal that the specific grinding force is lower when using the sharp ceramic alumina grit than that with the CBN grit, whereas an opposite result is presented as the grit wear is developed. The study demon-strates the possibility of dry grinding in terms of the wear mechanism, grit morphology, and temperature rise in the single-grit grinding.& COPY; 2023 CIRP. Published by Elsevier Ltd.
