摘要：
The actual grinding time and the variation of grinding forces during the grinding processes were analyzed. A grinding temperature simulation was put forward to predict the distribution of grind-hardening layer depths based on piecewise variable forces. Firstly, the grinding forces were discretized, and the corresponding heat flow density was calculated. Then, according to the actual contact length between the grinding wheel and the workpiece, the heat flow density was loaded onto the grinding surface, and the temperature field of the workpiece was simulated and analyzed. So the distribution of the grind-hardening layer was obtained. Finally, the comparison and analysis were carried out by the experiments and the traditional simulation method. The results show that the simulation may be more accurate to simulate the distribution of the grind-hardening layers along the grinding directions. © 2017, China Mechanical Engineering Magazine Office.
