摘要
本文应用最佳一致逼近及容差平滑的分段圆弧拟合列表点列平面曲线。本方法具有拟合误差最小;误差不大于给定值时,拟合圆弧段数最少;圆弧段交接处平滑性可控;一定的平滑数据作用,便于直接用于数控加工、绘图等优点和工程实用意义。
This paper presents a new method in which segmantal arcs of best uniform approximation and tolerance smooth are used to fit a plane curve consisting of listed points. The method possesses the advantages of the smallest fitting error, the least segments when the tolerance value is given, the control-dble smooth between the segments, the function of smooth data, and it can be . directly used to numerical control machining and graphing. It is applicable in Engineering.
