三维空间圆度误差评定的关键环节之一是基准平面的拟合,平面拟合的精度直接影响圆度评定结果的精度,只有满足“最小条件”的拟合平面才符合高精基准的要求,故于“最小二乘”拟合平面基础上寻求新算法,继续对平面作有意识的微小扰动,把平面度计算向“最小区域”不断逼近,收敛于真值,求得真正符合“最小条件”的拟合平面.

The fitting of the datum plane is critical to the evaluation of three-dimensional roundness error and the precision of plane fitting can affect the result of roundness. The plane fitting meeting the minimum condition is essential. Therefore,a new algorithm based on the least squares is examined in this paper. After a tiny disturbance on the plane,it converges to the minimum area by finding the plane fitting complying with the principle of minimum condition.
