摘要
在数控加工领域,通常需要用尽量少段数的圆弧样条来逼近三次Bézier曲线.给出了一种三次Bézier曲线的圆弧样条逼近的方法,该方法在给定误差范围内比单独使用双圆弧逼近所需的圆弧段数较少,且满足连续的要求.
In CNC, it is often required to approimate cubic Bezier curves by arc splines with few arc segments as possible. This paper presents a new arc spline approximating method for cubic Bezier curves, which reduces the number of arc segments under the given error tolerance, compared with biarc splines, and satisfies the continuity of.
