Abstract
Poor dimension and tolerance practices are a significant quality issue. It is estimated that 80 % of all manufacturing issues are directly related to improper use of GD&T. Therefore it is very important to define the permissible deviations from the ideal geometry as clearly as possible. That means suitable dimensional and geometrical tolerance indications in technical drawings are necessary. But the determination of optimal tolerances is not easy. Firstly, tolerances must always have a relation to function. Secondly, the indicated tolerances have to be produced. Thirdly, unambiguous and reproducible measurements of all given tolerances must be able. Functional tolerances need tolerance studies and knowledge about manufacturing and measuring is also required for design engineers.
