对于切削进给的前向刀具路径修正研究

Forward Tool Path Modification for the Regulation of Cutting Engagement

针对由Stori和Wright所提出的2D轮廓加工恒定切削率刀具路径生成方法的缺点,在分析传统刀具路径修正算法的基础上,提出了一种可以应用到任意几何形状的刀具路径中的优化算法,该修正算法修正最后一条刀具路径,使得刀具按恒定进给率进行切削加工,大大降低了刀具切削力的变化和刀具偏斜,减少了加工时间,提高了加工几何精度。并且将此算法应用于实际加工中,取得了良好的效果。

An improved algorithm for Stori and Wright＇s tool path modification approach which can generate a contour parallel tool path with constant engagement was proposed. The improved algorithm can be applied to modify the tool path of arbitrary geometry. By modifying the last tool path, this method can make the tool cut with constant engagement, reduce the change in cutting force variation and tool deflection, and reduce the machining time, improve the machining geometry, accuracy. The algorithm was demonstrated by some examples.
