Abstract: In order to research the distribution characteristics of workpiece grinding surface residual stress, grinding temperature field should be analyzed firstly. The influence of different grinding parameters on grinding zone temperature field was analyzed by using ANSYS through the established mathematical model of temperature field and heat transfer. The simulation results show that the influence of the cutting depth on the highest temperature is the largest. Using APDL program combined with the grinding force produced in grinding process, the thermal-mechanical coupling field of the grinding surface was simulated and analyzed. The size and distribution state of the residual stress were obtained and the thermal-mechanical’s influence on the residual stress was discussed and uncovered. Finally, the correctness of the simulation result was verified through the comparison of residual stress test results and simulation results.
