| Summary: | 碩士 === 國立高雄應用科技大學 === 模具工程系碩士班 === 96 === High speed, high quality, and short delivered time are the inevitable trend for the mold industry development. The aluminum alloy has easy milling and good mechanical property, which conforms to this current. The purpose of this study was to integrate Computer Aided Design and Manufacturing (CAD/CAM) into curved surface milling on the aluminum alloy workpiece, then use the Coordinate Measuring Machine (CMM) to measure the tolerance of geometry for gauging experiment workpiece. Furthermore, use Taguchi Method and the statistical principle to perform on the optimal parameters of the aluminum alloy curved surface milling, which are the optimized study to seek the best condition and contribution rate of control factor for curved surface milling.
The result of this study proved by Taguchi Method that the cutting feed rate was the most remarkable parameter for the all effects of control factor of the aluminum alloy curved surface milling process. The contribution rate of the cutting feed rate reaches as high as 37.424%, the milling speed is 20.812% to the next. The variation of system manufacture process improved, which is only 56.7144% of original one, and the accuracy of system manufacture process could enhance 1.65 times than before optimization. It is hoped that the concrete result could provide the manufacturer the basis of processing and measuring. Moreover, it could enhance the production quality and the efficiency in order to achieve the goal of high speed, high quality, and the short delivered time.
