This paper firstly summarizes two-dimensional numerical simulation of semi-fixed abrasive tool (SFAT), then three-dimensional model of SFAT is established by PFC3D (Particle Flow Code in 3 Dimensions). In order to make the compression ratio simulation match to experimental one about SFAT, the mechanical parameters of model are adjusted. In the direct shearing simulation, the relation between the shear stress and the horizontal shear displacement under different parallel bond stiffness are obtained. By Comparative Analysis the numerical results and test experiments of the direct shearing, the three-dimensional model of SFAT is further proven rational.
