A New Approach of Composite Surface Reconstruction Based on Reverse Engineering

Abstract

Reverse engineering technology plays an important role in reconstruction of a surface. It significantly 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 finds 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 infinitive surface. The infinitive surface's intersections are trimmed by boundary representation model reconstruction. The proposed methodology has several advan tages such as computational efficiency and automatic functional modelling in reverse engineering. Reverse engineering should be the 3D equipment of the photocopying process.
