Résumé
In order for manufacturing companies to thrive in an era of globalization, market pressures and technological developments, quality control is key. Without this aspect, it is not possible to ensure the functionality and quality of products. Due to errors that occur during the manufacturing process, manufactured parts have deviations from their nominal geometry. Therefore, one of the important aspects of the quality control of mechanical parts is geometric inspection. With the help of automated inspection, costs can be reduced during process. In our research project, we have focused on the profile inspection of non-rigid (flexible) parts. In fact, several mechanical parts used in the aeronautic and automotive industries can be considered non-rigid. This category of parts may have significantly different shapes in a free-state condition than the design (nominal) model due to gravity loads and residual stress. Generally, to solve this problem, special inspection fixtures are used in industry to compensate for the deformations of such parts to simulate the use state to perform geometric inspection. These dedicated fixtures are very expensive and the process is very time-consuming which reduces competitiveness. We aim to develop a nonrigid inspection technique to eliminate the need for specialized inspection fixtures by using a non-contact measuring system such as optical scanning and comparing the obtained point cloud from the distorted part with the nominal model to identify deviations. Using a nonrigid registration method and finite element analysis, we will apply a virtual (numerical) inspection fixture instead of a physical fixture. The simulated displacement will be performed with improved boundary conditions for simulating unfixed parts.
