Abstract
Bonnet polishing has the advantage of high removal efficiency and is widely used in aspheric manufacturing process. However, it is difficult to avoid the mid-spatial-frequency (MSF) error in the process of high efficiency bonnet polishing. Consequently, the paper established the precession simulation model of bonnet polishing, aiming to reveal the effect of precession mode on the surface error, and obtain the optimal precession mode to restrain the MSF error. The three precession modes, i.e., single-step precession, multi-step precession and continuous precession, were compared in simulation analysis and verified through the practical polishing experiments. The experimental results exhibited a good agreement with the theoretical results, which verified the correctness of the proposed model. The results shown that the optimal multi-step precession mode can not only restrain the MSF error, but also obtain better surface roughness. The paper demonstrated the validity of the multi-step precession polishing, which laid the foundation for the high-efficiency and high-precision manufacturing of large-aperture optical components.
