摘要: 发展了一个新的用于型腔模CAD/CAM集成的几何造型系统。系统中基本的输入方法为CSG的扫描。采用B-Rep方法作为物体的内部描述。基于此造型系统,发展了NC加工刀具轨迹的生成程序,证实了系统的CAD/CAM集成方案实用化的可能性。文中给出了一些有意义的例子。

Abstract: A new geometric modeling system for CAD/CAM integration of cavity dies and molds has been developed. The basic input ways were CSG and sweep. B-Rep method was adopted as the internal description of an object. The NC cutter path generation routies, based on the modeling, showed the significant possility to applications of the integration schama. A set of examples are given in the paper.
