This project proposed to develop a new approach of the mechanical structures geometry, called topological approach. This approach respects the actual trend on the machining system market as result of the ICT domain technologies. Analyzing the design and manufacturing process evolution we can remark that the interface between a mechanical component and the assembly is composed by an elementary surfaces group in contact with another surfaces group, in contact at nominal level. The surfaces group is regarded as a unitary geometrical group with complicated form.
Similarly at mechanical components we can remark that a surfaces group is generated by a single clamping in a single action. At control, the measuring device explores a surfaces group and returns the dimensional, form and position deviations. These facts suggest that is needed to use the notion of topological structure, defined as a structure composed by a surfaces group, belongs to the mechanical component, and which, associated with another group form an interface. The whole mechanical construction may be regarded as being composed by a number of mechanical components and joints. The assembly of these components and joints is similarly with a dimension chain. The overall objective of the project is to imagine a new theory regarding the geometrical aspects of the mechanical structures, theory based on the topological approach.
