摘要
用最小二乘圆法研究圆度误差评定问题．提出一种圆度误差评定的计算机算法．在微机上用Ｃ语言实现确定最小二乘圆圆心，并以此为评定基准计算轮廓曲线上到该圆心的最大和最小半径之差即为圆度误差。
The problem of evaluating roundness errors with the least square method is researched A algorithm on evaluating roundness errors using computer is issued.The center of a least square circle is defined as a datum point,and the difference of maximum and minimum radii in relation to the reference outline is the roundness error.A evaluating example using C langnage on a microcomputer is given.
