Quality control of quick response products by used of reverse engineering technologies

Error comparisons of fabricated parts and original CAD design is often a difficult yet important issue in product quality control. In this study, an integrated technique of 3D scanning with reverse engineering and rapid prototyping technologies proposed. This will be applied to the entire quality control phase of quick response products during the manufacturing process. For evaluation of presented approach, an automotive test model was made using the layered manufacturing process RP fabricator, a 3D Printing RP system. Then non-contact laser 3D scanner with RE software employed to evaluate dimensional deviations of manufactured RP model. Regarding to the result of inspection, maximum deviation was -0.306 mm. So. with the virtue of the 3D laser scanning system and RE software, the proposed method could be used during the entire quality control phase of the manufacturing process. © 2009 Asian Network for Scientific Information.
