摘要
一般的ＣＮＣ系统往往只提供直线和圆弧插补功能。尽管一些较新的系统也提供了二次曲线或某些样条曲线的插补程序，但仍然不能满足ＣＡＤ系统的曲线和曲面造型能力对ＣＡＭ系统的要求。本文研究了曲线的参数插补技术，提出了曲线的通用参数插补算法。
Conventional computerized numerical control (CNC) machines generally support only the functions of straight line and circular interpolations,the demand of most CAD systems which provide tools for 2D and 3D curves and surfaces can not be satisfatied even though some newer CNC systems also provide the interpolators of some quadratic curves or spline curves. In this paper,the parametric interpolating technigue is studied and a general parametric interpolating algorithm is proposed.
