摘要

摘要：为提高大口径非球面光学反射镜研磨与抛光阶段的加工效率，提出了采用多磨头组合加工方式同时提高材料去除效率和面形收敛效率的方法。该方法以矩阵运算为基础，在一次优化过程中同时对多个加工循环进行优化，将传统的单去除函数驻留时间求解过程进行扩展，实现多去除函数的综合优化求解。扩展了驻留时间求解范围，使大磨头和小磨头在加工过程中优势互补，实现多个磨头多个加工循环的全局优化。本文采用计算机虚拟加工的方法，对等厚和实际加工中的面形误差进行加工模拟分析，结果表明：与传统的驻留时间求解算法相比，在加工效率提高了50%的同时，RMS收敛率达到与小磨头相当。使用实际面形仿真加工结果RMS由0.0115变为0.0044，收敛效率为0.6212，满足实际加工要求。该技术可以有效缩短加工周期，具有很强的实用性。

Abstract

Abstract: In order to manufacture a large aspheric mirror in high efficiency and precision

a new method which uses multi-mode optimization was introduced. This method is based on matrix calculate

use different tool influence functions at one time when calculating dwell time

extending conventional calculation of dwell time to algorithm which uses a set of different TIF

extend solution area of dwell time. In the end did a simulation of polishing an error map with actual parameters using multi-mode method. The simulation result shows that compared to conventional way using multi-mode technique can improve efficiency by 50%

convergence rates of the RMS value better than before. When simulation on the real surface RMS changes from 0.115 to 0.0044

the convergence rates is 0.6212 which is satisfied for real manufacture. Multi-mode technique can improve polishing efficiency and maintain good precision

it can forms an attractive solution for the large optical aspheric mirror fabrication capability and has large potential.
