| Summary: | 碩士 === 國立高雄第一科技大學 === 機械與自動化工程所 === 98 === The present paper is mainly about using the image process technology to develop a 3D automatic measurement system. The system can automatically and rapidly gauge a small aperture of the workpiece, the center position of the circle, the range, the length and the angle of the geometrical shape. Through the optimization of light design, the 3D automatic measurement system will never stop until it achieves the efficiency of the gauging. This measurement system includes two kinds of system. First, optics servosystem: standardized system, turret type percentage, and zoom lens. Second, photo source servosystem: objective table, coaxial light, 4 split ring light, and colored photo source. Using QVPAK software from MITUTOYO Corporation, each measurement routine of the testing workpiece needs to be established in advance, and coordinates with the migration position of the 3D platform, then, transforms into the Visual Basic program. The system can automatically gauge a huge amount of the processed workpiece size. This experiment confirmed that the system gauging time is short, may avoid the personal error, and the accuracy may reach 0.002mm. Therefore, this research uses the Taguchi Method and fuzzy logic, develops a multiple quality characteristic calculating method which processes fuzziness project. This experiment designated the optimization design of the coaxial light and 4 split ring light for the improvement sign. It also combined the Taguchi Method and the Response Surface Method to enable the Multiple Performance Characteristic Index to achieve the goal optimization.
