Abstract: Grains have the impacting effect to the surface materials in grinding. In order to study the impact in the grinding process, the paper carried on the simulation by using DEFORM-3D software and conducted the grinding hardening experiment. It simulated the impact to the surface materials which was functioned by single grain and got the distribution of stress field of internal workpiece, analysed the equivalent stress and strain rate of surface of workpiece in the grinding process. It shows the analysis of equivalent stress reflected that grinding force is made up of a lot of surging force. The analysis of strain rate indicated that the impact and hardening effect to the surface of workpiece by grains is remarkable existing. The results of the experiment verified the correctness of simulation. DEFORM-3D simulation method could analyse and predict the parameter of surface hardened layer effectively.
