| Abstract: | In this paper,face grinding process with cup wheel was simulated based on the single-grit finite element model and material constitutive model by the use of FEM software ANSYS/LS-DYNA.The simulation results were analyzed,which showed the change law of the effective stress and total mechanical strain and effect of wheel speed agaist the grinding force intensity.The method proposed will provide an effective way and theoretical reference for the study on the principle of face grinding process as well as the parameters optimization. |
