提出了一种由参数化复合曲面生成无干涉刀具轨迹的方法。参数复合曲面是由参数曲面元素组成的曲面。该方法主要由两个步骤组成：从复合曲面中获取点，将其转换为三角多面体;然后从多面体生成刀具路径。在刀位数据的计算中采用了一种有效的算法，生成了适合金属切削加工的平面刀位轨迹。从由大量参数曲面组成的曲面模型获得所有刀具路径所需的时间很短。给出了一些真实的应用。
A method is presented for generating interference-free tool paths from parametric compound surfaces. A parametric compound surface is a surface that consists of parametric surface elements. The method is largely composed of two steps: points are obtained from a compound surface to be converted into a triangular polyhedron; tool paths are then generated from the polyhedron. An efficient algorithm is used in the calculation of cutter-location data, and planar tool paths, which are suitable for metal cutting, are produced. The time taken to obtain all the tool paths from a surface model that consists of a large number of parametric surfaces is short. Some real applications are presented.
