The grinding temperature field produced in the grinding process is a very complex process. The influence of grinding heat on the workpiece is a dynamic process (Chen & Wang, 2018). In order to study the law of grinding temperature field conveniently, it is necessary to establish a numerical analysis model of grinding temperature field. The grinding effect between the grinding wheel and the workpiece generates a lot of heat to the workpiece, so that the surface temperature of the workpiece will rise when the temperature reaches the critical value. It is also necessary to analyze the heat in grinding process continuously.
