摘要
建立了拟合任意圆弧段的三次参数矢量方程。在此基础上 ,用数学分析的方法从理论上证明了拟合半径函数与圆弧位置无关 ,最大误差处参数值与圆弧大小和位置均无关这两大拟合特性 。
First,this paper establishes a cubic parameter vector equation for imitating an arbitrary arc Based on the equation, two major characteristics are proved theoretically that the imitated radius function changes independently of the location of the imitated arc, and that the parameter value of th point where the maximum tolerance is acquired changes independently of both the size and the location of the imitated arc by means of analytical method Finally, the maximum tolerance value of the imitated arc frequently used is presented
