Unformatted text preview: ion and position defects which is necessary to allow to correctly adjust the production process. Lastly, the prototype software of three-dimensional metrology that we have already developed, shows that it is possible to directly use the fitting gauge model for the verification of the manufactured parts [Pairel, 1997]. 7. CONCLUSION The "fitting gauge model" enables to represent, in an extremely simple way, the near total of the standardized geometric tolerances as well as tolerances by zone which are impossible to express in the standardized graphic language. This representation guarantees the semantic coherence of the tolerances and can be directly used for the dimensional verification of conformity of the products and also by the manufacturing designer. We think that this model could represent any geometric tolerance by zone. It could be achieved by improving the model and the data-structure. The case of the geometric tolerances of lines (circularity, straightness, profile tolerance of any line) can easily be modelled by creating a line...
