摘要：
The machining precision of a cylindrical microlens array is usually very high, whereas the processing efficiency is very low. However, the processing efficiency can be considerably improved using a profile grinding wheel with a fine profile structure. To predict the surface shape error and surface roughness of a workpiece machined using a profile grinding wheel, a grinding simulation model was built for the profile grinding wheel. Then, the skewness distribution characteristics of the protrusion height of grains in the profile grinding wheel surface with a fine structure were analyzed and simulated using the filtering method. Subsequently, combining the outline of the grinding wheel topography and the run-out error of the grinding wheel, the entire grinding wheel in the space was reconstructed. Thereafter, a kinematics model of abrasive grains in the grinding wheel surface was created to simulate the surface topography of the grinding workpiece. Finally, a grinding experiment was conducted to verify the effectiveness of the simulation model. Relative to the experimental results, the errors in the PV, Ra, and Rz values of the simulated surface were 5.78%, 17.3%, and 12.9%, respectively. The proposed grinding simulation model can effectively predict surface shape errors and the roughness of grinding surfaces. © 2021, Science Press. All right reserved.
