摘　　要：针对复杂多曲面数控加工方法自动生成刀具轨迹的问题,本文提出并在ACIS几何造型平台上实现了一种采用截平面法进行复杂多曲面精加工刀轨规划的方法。该方法采用一组截平面去截取加工表面,得到一系列交线,将这些交线按一定规律排序,组成加工环,刀具沿着这些加工环运动,便完成模型的加工。通过实例证明运用该方法使生成的刀轨连续,进退刀得到优化,大大提高了加工效率。To solve the problem of automatic tool path generation of compound multi-surface finish machining,a tool path generation optimization algorithm is presented. The algorithm is realized based on ACIS. First,a series of intersections were acquired after Boolean add operation applied between a group of planes and model surfaces. Then a series of manufacture loops were constructed after collation. The tool moved around these manufacture loops .The numerical example shows the algorithm＇s high efficiency and realiability.
