Abstract: Through both of numerical simulation and experimental study, the grinding temperature field of WC-Co high hardness coating was analyzed. Based on the moving heat source theory, combining with the grinding conditions and the property of the workpiece, the temperature field model of diamond cup wheel grinding of WC-Co coating material was established and simplified through appropriate assumption. FEM (Finite Element Method) based numerical simulation of WC-Co coating grinding temperature field was then performed. A novel coating grinding temperature measurement method was proposed to experimentally research the grinding temperature. A good agreement has been achieved between the simulation and experiment, which shows the proposed methodologies can be effectively applied to analyze the coating grinding temperature and provide a means for research on the high hardness coating grinding mechanism.
