摘要:

通过对NURBS造型方法技术的研究,在我校自主开发的SuperManCAD/CAM集成系统中成功地实现了基于复杂曲线的NURBS双向蒙皮曲面的造型功能,建立了完全基于NURBS方法的CAD/CAM系统。大量的工程应用和实例验证,表明本研究的NURBS方法是一种适用于复杂外形产品设计与制造的、灵活有效的造型方法。

关键词: NURBS, 双向蒙皮曲面, 节点插入, 升阶

Abstract:

By deep research on NURBS modelling method, a new modelling function in NURBS for skinning surface bidirectional interpolating via complex curves is realized in SuperMan CAD/CAM integrated system, completely based on NURBS method. Various examples coming from engineering applications show that the new method is flexible and effective, which can meet the needs of product design and manufacture with complex forms.

Key words: NURBS, biskinning surface, insertingk not, degree elevation
