摘要
本文用最小二乘法对列表曲线进行圆弧拟合,以一段或多段圆弧替代列表曲线。用此法可计算出列表曲线和函数曲线加工时所需的数据,也可作数学和力学分析,形状误差判定。
the article explain using least-squares to do arc fit for list-curve,use one section arc or multi-section arc substitute the list-curve.This methods can get data that machining of the list-curve and function-curve need,and do analyse of math and dynamo and judging of error.
