This study proposes two path generation algorithms to diminish the superposition of the convolution effect on the polishing path in computer-controlled optical surfacing. According to the polishing of aluminum-alloy based hyperboloid optical components, different proportions of polishing agents were blended. Then, the surface roughness of the optical components were determined through a validation experiment of the algorithms. Furthermore, the relationship between surface roughness and the polishing agent concentration, and the compensation strategies for surface roughness were analyzed. The results show that the two algorithms effectively compensated for surface waviness. The findings support the strategies for improving the surface quality of optical components with aspherical surfaces.
本研究提出了两种路径生成算法，以减少计算机控制光学表面成形中卷积效应在抛光路径上的叠加。针对基于铝合金的双曲面光学元件进行抛光，调配了不同比例的抛光剂。然后，通过算法的验证实验确定了光学元件的表面粗糙度。此外，分析了表面粗糙度与抛光剂浓度之间的关系以及表面粗糙度的补偿策略。结果表明，这两种算法有效地补偿了表面波纹度。这些发现为提高非球面光学元件表面质量的策略提供了支持。
