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. Based on the NURBS mathematical model, the surface modeling and processing system are studied.On the basis of the analysis, research and improvement of various algorithms, a CAD / CAM integrated surface modeling and processing system with multiple functions is completed, Reasonably NURBS main core supporting technologies and algorithms used in the NURBS modeling system, through the successful realization of a variety of interactive curves and surfaces (lines, arcs, quadratic curves, free curves, surfaces, quadrics, Rotating surface, ruled surface, sculpture surface, cross-section surface, free-form surface, complex combination of surfaces, etc.) modeling generation.
