根据最小条件确定直线度误差与平面度误差是一种科学方法。目前,世界上不少国家在基础国家标准中正式采用了按最小条件评定直线度误差与平面度误差,我国国家标准也作了这个规定,但在实际测试工作中,仍往往采用不符合最小条件的方法处理。因此,探索符合最小条件的计算方法,成为推行国家标准的关键.
According to the minimum conditions to determine the straightness error and flatness error is a scientific method. At present, many countries in the world formally adopted in the basic national standards to assess the straightness error and flatness error according to the minimum condition. Our country’s national standard also made this requirement. However, in the actual test work, it still often adopts the non-compliance with the minimum conditions Approach to deal with. Therefore, to explore the calculation methods that meet the minimum requirements has become the key to the implementation of national standards.
