摘要

提出了一种新的进动气囊抛光驻留时间算法

用于实现高精度的光学玻璃零件的加工.首先

通过抛光工艺试验确定抛光去除率函数;在矩阵迭代算法的基础上

给定一个合适的驻留时间初值函数.然后

采用分层阈值去除法进行驻留时间的优化求解

并加上残余误差方差最小的判定条件

从而得到完整的驻留时间函数.该算法适用于非球面、自由曲面等光学玻璃元件的抛光加工.用MATLAB对残余面形误差进行了仿真

仿真结果表明残余误差精度PV值可以收敛到0.1

m左右.最后

对光学玻璃平面进行了抛光.实际抛光后

该玻璃表面粗糙度

从抛光前的0.159

m减小到0.024

面形精度PV值由抛光前的0.756

m减小到0.158

m.得到的结果验证了提出驻留时间算法的合理性

表明该算法可为以后进行复杂面形工件的气囊抛光研究提供理论基础.

Abstract

A key dwell time algorithm in bonnet polishing was investigated to get the high-precision optical surface. Firstly

the removal function of bonnet polishing was acquired from the process experiments. Based on the matrix iteration

an appropriate initial dwell time function was given to calculate the dwell time with the liminal removal method. Then

the variance of the residual error was considered to optimize the result of dwell time function and to acquire the dwell time function quickly.The method is suitable for polishing the optical elements such as aspheric surface

and free-form surface. A simulation experiment was performed on a residual surface error through MATLAB

and the results show that the residual error PV value has reached up to 0.1

m. Finally

an optical glass surface was processed on the bonnet polishing machine developed by ourselves

and results show that its surface roughness

is reduced from 0.159

m to 0.024

m and the PV value from 0.756

m to 0.158

m. Moreover

the rationality of the dwell time algorithm was verified. It demonstrates that the matrix-based algorithm satisfies the requirement of optical precision machining very well and provides theoretical basis for bonnet polishing of complex optical elements.
