This thesis presents the work carried out under a concept associated with a research project inspired by the problems encountered in the industrial environment.
The objective of the project is to evaluate the tolerancing of CAD models in aerospace design. Investigation of new methods of tolerance analysis that could be developed or automated to reduce the number of errors and problems related to tolerance at the manufacturing or assembly phase.
With the high use of MBD (Model-Based Definition), the proposed model will make it possible for designers to predict some tolerance issue in advance. The tolerancing must therefore be defined in the 3D model, using tools such as FT&A (Functional tolerancing and Annotation) workbench.
In practice, errors are encountered when the GD&T specified in a CAD model is inconsistent with the dimensions or function of the part. Either because the tolerances are too tight so we cannot manufacture the part, or too loose, so there are issues when assembling the part on its environment.
The method proposed in this project is to be based on the IT (standard tolerance degrees), an interesting information which is underused during the engineering phase in the current industry. The tolerancing allocation on an MBD allows us to estimate this IT and take advantage of that input by minimizing the risk of errors in aerospace engineering parts.
