数控编程列表曲线的空间矢量法

Research on NC Programming Method of Tabulated Curve

提出了一种数控编程空间列表曲线的矢量法——空间三次参数样条曲线法 ,介绍了该方法的基本原理 ,导出了空间三次参数样条曲线的数学模型的矢量表达式 。

This paperproposesa method to build the mathematical model ofspatial spline curve.The basic principle of the method is introduced and the vector representation formula of space spline curve model is derived The NC machining is also developed in this paper.
