RÉSUMÉ. Le tolérancement traditionnel considère la conformité d’un lot lorsque le lot de production satisfait les spécifications. La caractéristique est considérée pour elle-même mais pas en fonction de son incidence dans l’assemblage dont elle fait partie. Le tolérancement inertiel propose une autre alternative de tolérancement afin de garantir l’assemblage final. L’inertie I= δ + σ n’est pas ...

An image is never noise free. Visual inspection of a part from its image is therefore affected by image errors. Understanding how image errors affect measurement precision is therefore critical for accurate inspection. In this paper, we lay out a statistical framework that allows to explicitly handle image errors and characterize their impact on measurement precision. A hierarchical model is al...

The relationship between tolerances of statically measured geometric parameters and the aerodynamic performance of a sample of manufactured airfoils is investigated in this thesis. The objective is to determine which geometric parameters are the best discriminators of performance, and how these best discriminators are affected by changes in design methodology, manufacturing precision, and desir...

The development of complex products with high quality in dynamic markets requires appropriate robust design and tolerancing workflows supporting the entire product process. Despite large number methods tools available for designers tolerance engineers, there are hardly any consistent approaches that applicable throughout all stages. This is mainly due to break between primarily qualitative conc...
