Abstract

The repairing of incomplete measured data caused by the inaccessibility or invisibility of some portions of the product surface for measure tools plays an important role in Reverse Engineering. The fundamental principles of Reverse Engineering and Anatomical CAD are introduced. The main functional advantages of 3-matic package integrated with Anatomical CAD are presented. There is a big difference in the working flows between Anatomical CAD and traditional CAD packages in the process of RE data repairing. In this paper, we propose a new method of data repairing based on Anatomical CAD. The point cloud of the stamping part obtained by a Potable CMM is repaired successfully by 3-matic, which reduces preparation times by working with a triangular mesh directly, and saves the turn-around time and works more effectively.
