Abstract: This paper establishes the kinematics model, elastic deformation model and plastic accumulation model of the engineered grinding wheel and makes the numerical simulation of the surface topography of the engineered grinding wheel with quenching 45 steel as the research subject. The results show that when the axial grains of the grinding wheel are the most densely arranged and the offset distance of the grains is greater than 0 and less than 25% of the average diameter of the grains, the good surface roughness can be obtained after grinding. Compared with the arrangement schemes in which the offset distance of the grain is 0 and 50% of the average diameter of the grains, the scheme in which the offset distance of the grain is 25% of the average diameter of the grains can get the best surface topography, surface profile curve and surface roughness of the workpiece.
