Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Most models for computer aided tolerancing proposed by researchers and used in industry do not fully conform with standards. Moreover, most of them make severe assumptions on observable geometric deviations and can therefore hardly handle all kinds of 3D
