Abstract

Modeling of grinding workpiece surface topography is the foundational research about the service performance of the workpiece surface. In this paper, we focus on the real surface topography modeling of the grinding wheel and the digital generation method of the grinding workpiece surface based on the real surface of the grinding wheel. First of all, the grinding wheel surface is restructured based on the measured grinding wheel surface data after completing the filtering process and getting the characteristic parameters from the moving-average model to solve inaccuracy problem. According to the grinding kinematics, the motion trajectory equations of the abrasive grains are established. The surface topography of the workpiece is generated by the Boolean operation, and the optimization algorithm is used to solve the problem of large amounts of calculation and long operation time in the numerical modeling of 3D surface topography. Finally, the accuracy of the model is verified by comparing with the characteristic parameters of the groove and the roughness parameters of the experimental surface, which are the most important parameters in the surface topography.
