An Adaptive Tolerance Model For Collaborative Design

To ensure the robustness of geometric tolerancing in collaborative design, a multi-view tolerance data representation is needed as well as a multi-level representation. The goal of multi-level representation is to detail the tolerances as the knowledge of the product progresses during its development. After a brief discussion, IPPOP product model and GeoSpelling tolerance model are chosen as basis of definition and implementation of an adaptive tolerance model. In this model, the multi-level and multi-view capabilities are permitted by level and view adaptations. Level and view adaptations consist in an evolution of the viewable tolerance data according to the step of design and to the actors. These adaptations are presented and applied on a part of an automated cutting machine for fabrics.
