摘要：

考虑到光学自由曲面慢速刀具伺服车削缺乏切削轨迹点选取位置和数量的依据，提出了主动控制加工误差的刀具路径生成方法。进行了刀触点、刀位点轨迹分析和慢刀伺服车削正弦波面试验，结果表明，本文方法可以预测加工表面精度并可以显著降低切削点数量。

Abstract:

A tool path generation method for active control machining errors is proposed taking into consideration that, in optical freeform surface slow tool servo, the location and quantity of cutting location points selection are lack of basis. The cutting contact points and cutting location points are analyzed using this method. The experiment of slow tool servo for sine?wave surface was carried out. The results show that the proposed tool path generation method has the characteristics of predicting machining surface accuracy and significantly reducing the number of cutting location points.

Key words: machine tool, ultra?precision machining, slow tool servo(STS), optical freeform surface, tool path generation
