Abstract: Computer-aided tolerancing (CAT) aims to predict and control geometrical and dimensional deviations in the early design stage. Former simulation models based on the translation and rotation of nominal features cannot fulfill ...

Abstract: In order to tackle the ambiguities of geometrical product specification (GPS), GeoSpelling language has been developed to express the semantics of specifications. A detailed syntax of GeoSpelling is proposed in this paper. ...

Abstract: This article deals with the behavior of a planar joint taking surface defects into account. Two theoretical concepts are used: gap hull and difference surface. Gap hull represents the displacement space characterizing all ...
