Unformatted text preview: t the best assumptions for modeling. With nominal model, all the variations cannot be imagined, and their influences on the functioning cannot either. Before managing variations on parts and product, it is useful to express mathematically the different parameters involved in the behavior of the mechanisms. With the different operations and in particular the filtration operation, it will be possible to have a good link between micro and macro geometry. In geometrical specifications, micro geometry generally concerns roughness and waviness, macro geometry concerns form, orientation and location. Until now, the standards are not very clear on this subject and there are also different explanations considering the micro or the macro point of view. This aspect is an important point for a unified approach. With GeoSpelling concepts it is possible to describe micro specifications in the same way as macro specifications. Only six operations are useful to create all the geometric features involved in micro and macro geometry....
