摘　　要：三角曲面造型方法因能有效地解决构型复杂、形状和边界不规则产品的三维离散数据曲面造型问题,已成为CAD/CAM技术研究的新热点。本文讨论了三角曲面造型方法在复杂曲面模具CAD/CAM中的一些关键技术,同时以三角曲面造型方法为手段,在微机UNIX环境下研制开发了一个交互式汉化CAD/CAM软件系统,作为现有CAD/CAM软件的重要补充。Because of the ability to settle the problem of modelling of 3-D discrete data curved surface for the products with complex configuration and irregular shape and boundary,the triangle curved suface modelling method has become the central issue in the research of CAD/CAM technology. In this paper, some key technology about the triangle curved surface method in complex curved surface mould CAD/ CAM is discussed. At the same time, As the complement of CAD/CAM software existed by using the triangle curved surface method. A mutual Chinese CAD/CAM software system is developed in the PC -unix enviroment.
