A NEW KNOWLEDGE BASED APPROACH THE REVERSE ENGINEERING OF A PRODUCT
Current (RE) approaches are based on frozen models (parametric surface approaches) and are hardly re-usable. Consequently, the possibility of re-engineering or re-design does not exist. This paper proposes a new research direction taking into account product lifecycle knowledge. The research direction combines a geometric approach to a functional approach for formalizing and semi-automating the rebuilding methodology. This methodology is presented and the geometrical recognition and the knowledge identification phases are set and data are organised in a functional and structural skeleton. Finally, a use case of the journal cross of a Peugeot 403 is presented for illustrating the approach.
