A New Approach of Composite Surface Reconstruction Based on Reverse Engineering

Reverse engineering technology plays an important role in reconstruction of a surface. It signicantly reduces the reconstruction time and the costs of the part duplication. This paper presents a new approach to the reconstruction of a surface. The proposed methodology nds the basic parts of the surface and blends surfaces between them. Each basic geometric part is divided into triangular patches which are compared using normal vectors for face grouping.. Each basic geometric surface is then implemented to the innitive surface. The innitive surface’s intersections are trimmed by boundary representation model reconstruction. The proposed methodology has several advan tages such as computational efciency and automatic functional modelling in reverse engineering. Reverse engineering should be the 3D equipment of the photocopying process. © 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of [name organizer]
