碩士 === 國立臺灣大學 === 機械工程學系 === 85 === In order to enhance the production efficiency of dies in Taiwan, we explore "High Speed Milling" and "Rapid Prototyping" to apply to die manufacturing. Hoping to shorten the cycle time of production and decrease the production cost. In the process of high-speed milling, increasing cutting speed of machining directly enhances productivity. This research designed an experiment to report the situation in the process of high-speed milling applying to die manufacturing, and measured the machining time and results in comparison with current process nowadays. The results of experiment show that the surface roughness values (Ra) of tool steel were as low as 0.5μm achieved by high- speed milling. Moreover, the productivity in high- speed milling is 4.5 times of that in conventional milling. In the other hand, the Rapid Prototyping technology just develops to maturity and adapts to business use in the late 10 years. This thesis, then, specially introduces its theory basis and development, and analyzes its applying values in the design and manufacturing of molds.
