Applications of 3D scanning and reverse engineering techniques for quality control of quick response products

Quick error comparisons of fabricated parts and an original CAD design is often a difficult yet important issue in product quality control. In this paper we present an integrated technique of 3D scanning with reverse engineering and rapid prototyping technologies. This will be applied to the entire quality control phase of quick response products during the manufacturing process. By using 3D scanning and reverse engineering technology in conjunction with rapid prototyping technology, the geometric data of components can be easily and rapidly measured and analyzed. The detailed report can be printed out directly to fulfill the requirement of total quality control for quick response products. The proposed technique is especially suitable for fragile or soft material made products, like thin shell or rubber parts. With its accuracy and ease of operation, this integrated method is able to help manufacturers improve their global competitiveness in the 21st century.
