Méthodologie de passage d'un modèle CAO vers un modèle FAO pour des pièces aéronautiques:Prototype logiciel dans le cadre du projet USIQUICK

Abstract : Automating the CAD/CAM process needs the conversion of the CAD (Computer-Aided Design) model into a CAM (Computer-Aided Manufacturing) model designed to support the tasks associated to manufacturing planning (process planning, fixture selection and tool path computation).
Our work, within the framework of the RNTL USIQUICK Project, is to propose a conversion methodology in order to obtain a CAM Model dedicated to 5axis aeronautical parts milling.
The first part of this document presents a state of the art of the different classical feature recognition methods. It underlines the fact that none of these methods is adapted to aeronautical parts. We then propose to design a specific CAM model directly based on the BRep CAD Model, in which are added information related to the different milling possibilities of the different faces. Every face of the model is then considered as an “elementary” manufacturing feature.
To obtain this specific CAM Model, we present in the following our conversion methodology, which is composed of a static view (data model) and a dynamic view (conversion process). The second part of this document presents the static view, i.e. the data model needed for the conversion process. It is obtained thanks to the VIM (Viewpoint Integration Modelling) methodology. The dynamic view, explained in the third part of this document, is composed of two major steps: the first one, called “enrichment”, adds some geometrical and technological data to the CAD model, and the second one, called “manufacturability analysis”, adds information related to milling processes that could be used to realize the part. It finally ends to the CAM Model composed of elementary features.
In a last part, we propose a software prototype developed for CATIAV5®, in order to validate our works. We then present some results of our software on several aeronautical parts.
