摘要

慢刀伺服(STS)车削技术是加工自由曲面光学元件的一种有效方法。但是在慢刀伺服车削过程中,面形的矢高和口径大小会影响加工精度。针对这种情况,通过研究慢刀伺服车削等弧长法和等角度法的线性化误差趋势,提出了一种先等弧长、后等角度的组合车削轨迹优化方法。为实现车削轨迹的合理规划,对新的车削轨迹衔接点的选取进行了优化设计,利用MATLAB软件以正弦网格曲面为例进行仿真,结果表明该车削轨迹优化方法能够有效提高其面形精度。

Abstract

Slow tool servo (STS) diamond turning technology is an effective method to process freeform surface optical elements. However, in the process of slow tool servo turning, the machining accuracy is affected by the sagittal height and caliber of the surface. Aiming at this situation, by studying the linearization error trend of the constant-angle and constant-arc methods in STS diamond turning, a tool path generation optimization method combining the constant-arc and constant-angle methods is proposed. In order to realize the reasonable planning of the tool path, joint point selection of the new tool path is optimized. The simulation is applied to the sinusoidal grid surface with MATLAB, and the result shows that the tool path optimization method can effectively improve the surface accuracy.
