Unformatted text preview: clude all the geometric features and all the parameters to describe the functionalities of a product. For example, the geometric model proposed by Prof. Clement, based on the TTRS [Clement, 1994], model could be a good way to build a complete and coherent tolerancing process. This model is able to describe all the ideal geometry involved in a nominal model for each stage of the tolerancing process. But it must now take into account tolerances and explain how ideal geometry is connected to actual parts. Coherent and Complete Tolerancing Process 39 The geometric variation aspects are not only, functional aspect but also assembly, manufacturing and metrological aspects. The mathematical model used to describe the ideal geometry of the product, the non ideal geometry, the variation and its limits has to cover all the needs for each activity of the tolerancing process. The following chapter presents GeoSpelling, the first solution for a coherent and complete tolerancing process. 3. THE UNIFIED DESCRIPTION BY GEOSPELLING 3.1. GEOSPELLING GeoSpelling is a mode...
