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。

关 键 词:NURBS  插值  数控加工

Abstract:Taking the popular Non-UniformRational B-Spline(NURBS) as a mathematical model, a surface modeling and processing system is studied in this paper, a CAD/CAM software system of surface modeling and machining is completed. The main techniques(elevation, kont insertion) of B-Spline is applied to system based on NURBS, many kinds of modeling (line, arc, 2-degree curve, free-form curve, plane surface, 2-degree surface, ruled surface, sweeping surface, skinning surface) are successfully laid out
Keywords:Nonuniform rational B-spline(NURBS) interpolation multiple-knot cutter location NC
