摘　　要：针对目前椭圆锥面展开CAD需要近似解析推导公式和参数化编程的情况,运用数学分析及几何理论的方法,提出了如何通过数学建模来解决工程中复杂的相交斜椭圆锥管的自动放样问题的方法,并在O b ject ARX环境下编写了高效的C++程序,以达到在数控机床上快捷、精确的自动下料.最后,给出了应用实例,证明该方法简单、直接,易于理解与操作,便于工程实际应用.Considering the condition that drawing a developmental figure of an elliptic cone requires some analytical deriving and parametrical programming, and using the method of mathematical analysis and geometrical theory, this paper introduces a lofting method, faamely, to use mathematical models to solve the problem of lofting for complicated, intersected, thin, and off-angle elliptical cone tubes. An efficient C＋ ＋ program is designed additionally in the environment of Auto CAD Object ARX so that swift and precise cutting of sheet metal can be automatically done on a numerically controlled machine. And finally, a practical example is given to indicate that the method is simple and convenient in practical use.
