The Basic Theory of Reverse Engineering
The Concept of Reverse Engineering
Reverse engineering [1, 2, 3, 4], is based on modern design theory, method, and technology, to dissect, analyze, and recreate the existing products. Compared with the forward engineering, the differences are that it carries out some testing analysis for the existing product model and obtains the 3D contour data of the object. And then it deals with these data and proceeds 3D reconstruction and sets up the CAD data model. Engineering designers work on the CAD model for improvement or redesign, then they output the standard data file to rapid prototyping (RP) system or generate NC code to CNC machining system directly to generate realistic product or its mold. Finally, they will put it into production after the verification of experiment and finalizing the design product. Thus, reverse engineering technology is an effective way to shorten the development period of product, especially for the objects with complex...
