摘　　要：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.
