摘要 常规几何模型通常难以胜任一些复杂曲面产品的计算机辅助设计/计算机辅助制造问题,为此,提出了应用于计算机辅助设计/计算机辅助制造的基于点的几何模型概念,给出了基于点的几何模型的定义及其计算机辅助设计/计算机辅助制造应用流程,研究了基于点的几何模型的几何特性、计算机辅助设计方法、计算机辅助制造方法及其计算机辅助设计/计算机辅助制造系统开发方法。在鞋楦计算机辅助设计/计算机辅助制造中的应用表明,基于点的几何模型有常规几何模型所没有的特性,能够实现某些特殊产品的计算机辅助设计/计算机辅助制造。 Conventional geometric models couldn't meet the needs of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) of products with complex shape. In order to solve this problem, a point-based geometric model applied to CAD/CAM was put forward. The definition of point-based geometric model and its application process of CAD/CAM were presented. The geometric properties, CAD method, CAM method, and CAD/ CAM system development method of this model were studied. The CAD/CAM application of shoe last showed that point-based geometric model was superior to conventional geometric models, and could realize CAD/CAM in some special products.
