碩士 === 大葉大學 === 工業工程與管理學系 === 104 === Along the development in modern technologies, products are gradually become rapid production (RP) and manufacturing oriented. 3D printing technology and 3D scanner are applied with the reverse engineering method to shorten the modeling and process time for making products. This study used Reverse Engineering and contactless 3D optical photographing techniques to compute and process the captured scanned image by computer, in order to obtain the 3D external appearance of the canned object. The main products investigated in this study were composed of irregular curved surfaces, such as arts, science, virtual reality (VR), animation, industrial design, etc., many industries can apply such technique. For example, objects like fan blade and turbine blade that are difficult to obtain their CAD models, the technology of Reverse Engineering can be applied to obtain related information of design and production for them. This study was mainly illustrated that the problems may be encountered in the practical optical scanners, and their operations, including factors of colors, materials and reflection rate. By taking the irregular curved surfaces of rotary blade as an example, used Reverse Engineering and DAVID 3D Scanner software to build its CAD model, and scanned it with different measurement parameters. Then, compared and investigated the scanned results, and sorted out the optimal measurement parameters from different results in order to build a complete CAD geometry model to be the lead-time preparation for computer-aided manufacturing; in addition, combined with 3D printer to print products with the highest similarity.
