| 摘 要： | 通过对AutoCAD软件中各类样条曲线的功能及其DXF组码深入分析，并用objectARX二次开发环境进行编程验算，反求出了AutoCAD中的双圆弧样条曲线、NURBS样条曲线以及B样条曲线的具体实现技术及教学模型，并对AutoCAD环境下各类样条曲线的数控加工编程进行了讨论。这些为更好地、准确地应用这些样条曲线功能来从事设计、制造及CAD／CAM软件系统开发提供了理论基础。

| Abstract: | After analyzing profoundly the function and its DXF group codes of various kind of spline curves in AutoCAD software as well as programming verification based on object ARX development environment, this paper finally reversed their developing technique and mathematic models of biarc spline, B-spline and NURBS(non-uniform rational B-spline) curve in AutoCAD software. And the methods of NC machining programming of these spline is also discussed. |
