This document discusses a finite element model for predicting temperature distribution in a workpiece during surface grinding. It begins by reviewing how various grinding parameters affect temperature and describes modeling the grinding zone as a heat source moving along the workpiece. It then presents the developed finite element model, which calculates the heat flux into the workpiece based on grinding wheel speed, workpiece speed, and depth of cut. The model is used to simulate temperature distribution and predict maximum surface and subsurface temperatures under different grinding conditions. Results show highest temperatures occur at the trailing edge of the grinding contact area and just below the workpiece surface. The model provides a way to analyze thermal effects and optimize grinding parameters to control temperatures and residual stresses.
