A Reverse Engineering for Manufacturing approach
Résumé
Defining a Computer Aided Process Planning (CAPP) model from a physical part is an important issue in product improvement, remanufacturing and quality control. Reverse Engineering (RE) is a process that allows to convert low level geometric information like 3D points cloud to high level information such as CAD model, CAPP model etc. There exist two approaches to obtain a CAPP model for a physical part. The first one is to reconstruct a CAD model of the part to be reversed, which then is reintroduced in the conventional product lifecycle. The second one is to directly identify manufacturing operations and define a new process planning from 3D information. This paper proposes an approach called Reverse Engineering For Manufacturing (REFM) which allows to directly obtain a CAPP model from 3D information and the skills of a user.
