摘要
以NURBS为数学模型,对曲面造型及加工系统进行了研究.在对各种算法分析、研究和改进的基础上,完成了一个集CAD/CAM于一体具有多种功能的曲面造型及加工系统,合理地将NURBS的主要核心配套技术和各种算法运用于NURBS造型系统中,通过交互方式成功实现了对多种曲线曲面(直线、圆弧、二次曲线、自由曲线、平面、二次曲面、旋转面、直纹面、雕塑曲面、截线面曲面、自由曲面、复杂组合曲面等)的造型生成.
In this paper, a surface modeling and processing system is studied and a CAD/CAM system of surface modeling and machining is completed by taking the popular Non - Uniform Rational B - Spline （NURBS） as a mathematical model. The main techniques （elevation, kant insertion） of B - Spline are applied to system based on NURBS, many kinds of modeling （line, arc, 2 - degree curve, free - form curve, plane surface,2 - deree surface, ruled surface, sweeping surface, skinning surface and so on） are successfully laid out.
