一、采用最小区域法评定平面度误差的现状平面度误差值的求解方法,在计算机还没有普及的情况下,多采用对角线法,基本上是将对角线法测得的结果转化成原始矩阵图后,直接取最大值和最小值之差。但是误差是不可忽略的。据统计,按对角线法评定的平面度误差比用最小区域法评定的平面度误差值约大10％以上。 First, the use of the smallest regional assessment of flatness error flatness error value of the solution method, the computer is not universal case, the use of diagonal method, the dialectic method is basically the result of the test into After the original matrix, the difference between the maximum value and the minimum value is taken directly. But the error is not negligible. According to the statistics, the flatness error evaluated by the diagonal method is about 10% more than the flatness error evaluated by the minimum area method.
