Abstract
This paper used spatial random cutting plane method for modeling the real irregular grain shapes, and method of smoothed particle hydrodynamic (SPH) was used to establish CBN grinding wheel abrasive wear model. In order to research the wear mechanism of CBN abrasive and the relationships between grinding parameters and grinding wheel wear, simulation of the wheel abrasive wear process was simulated by the LS-DYNA explicit dynamics. According to the results obtained by simulation of abrasive wear model which has the same law with the actual wear abrasive, it is has realistic instructive significance to the actual grinding process of vitrified CBN grinding wheel.
