摘　　要：我国空间遥感、深空探测、空间战略装备等国家重大工程的快速实施,对大口径复杂曲面光学元件的高效制造提出了要求。为了提高光学加工中研磨阶段的效率,提出了基于工业机器人的柔性磨削技术。分析并比较柔性磨削技术与传统刚性磨削、传统研磨技术的差异,提出了等体积去除模型并验证其正确性。研究了磨削去除体积与驻留时间、压力以及转速的关系。实验条件下,柔性磨削去除效率为0.59mm^(3)/s,高于传统小磨头研磨效率8.4×10^(-2)mm^(3)/s。论文提出的柔性磨削技术为大口径碳化硅空间反射镜高效磨削提供一条新技术途径。The rapid implementation of national major projects such as space remote sensing,deep space exploration,space strategic equipment in China,requests the highly productive manufacture of large-aperture complex optical components.A flexible grinding technique based on industrial robots is suggested to increase the processing effectiveness of the grinding stage in the optical processing process.The differences between flexible grinding technology,class rigid grinding,and conventional grinding technology are compared.And a const-volume removal characteristic model for flexible grinding is presented and proven.Investigation is done into the connections between dwell time,pressure,and rotational speed and grinding removal volume.In the experiment,the grinding removal efficiency of flexible grinding was 0.59mm/s which was higher than that of conventional small tool grinding which was 8.4×10^(-2)mm^(3)/s.For the effective grinding of large diameter SiC space mirrors,the flexible grinding method put forward in this study offers a novel technological solution.
