摘要	Planetary grinding technology can effectively improve material removal efficiency by improving the relative velocity of grinding contact points. However, the uneven wear of the traditional grinding disk (or grinding plate) results in the continuous change of the shape of the grinding disk, which affects the stability and accuracy of the removal function in the grinding process, and also limits the application of this technology. In this study, based on the planetary motion mode of a small grinding head, the wear function was established and the curvature radius of the grinding disk was preset to ensure that the removal amount at each point of the grinding disk was equal after a single processing cycle to improve the removal function stability. Experimental verification was also carried out, and the grinding removal function was found to be consistent with the simulation calculation results obtained using the model, which verified the accuracy of the model. Finally, an efficient and stable removal function was obtained by using the optimized grinding disk. A SiC grinding disk with a diameter of 40 mm was used to grind the SiC workpiece. The experimental results showed that the surface shape changed by less than 1% after comparing the wear of the disk before and after machining, and the volume removal error was less than 2.3%, which meets the stability requirements of the optical grinding removal function. Under the conditions of revolution at 100 rmin-1 and rotation at -100 rmin-1, the volume removal rate reached 6.879 mm3min-1. Compared with the single rotation grinding with the same parameters, the removal amount of 40.9% was increased, which proved that the planetary grinding technology can obtain a highly stable and efficient removal function based on parameter design, and provided reliable theoretical guidance for the application of planetary motion grinding technology in the efficient processing of SiC mirror. 2021, Science Press.
