My research deals with the geometric quality control of complex shaped parts in the context of digital continuity. To carry out this work, it is necessary to master the control process of a component in relation to the functional requirements.

The first objective is to identify functional requirements and translate them into ISO geometric and functional specifications by a synthetic method.

The second objective is to allow the specification of acceptable shapes of a complex surface. Indeed, some surfaces cannot be defined by a simple shape defect. In the context of conformity control, modal expertise makes it possible, first of all, to highlight the elementary defects that cause non-conformity. And in a second time, it allows to help the tolerancing and the research of new types of specifications to express, just necessary, the requirements expressed by the experts.

All these works must be carried out in a continuous cycle numerically of design, manufacture and control. Indeed, the different methods and tools developed will have to allow a propagation of the modifications throughout this same product cycle.
