碩士 === 長庚大學 === 機械工程研究所 === 89 === Electrical-discharge machining in the mold and die manufacture isn’t unobtainable process. It is important that electrical-discharge machining is in the mold and die manufacture process, especially for high hardness and strength. Although it isn’t affected by material hardness and strength, it compares with other initiate mold and die manufacture that process is very slow. If it speeds up the process, dimensional accuracy and surface roughness are not perfect. It can promote remarkably electrical-discharge machining in the mold and die manufacture, if it develops a high speed of electrical-discharge machining with dimensional accuracy and surface in-tegrity process technology. Our study uses dynamic characteristic theory of Taguchi method, de-fines three ideal function modes, and discusses electrical-discharge ma-chining of the combination parameters of the related optimization process development. From the results of experiment, dimension vs. dimension ideal function mode can obtain the best dimensional accuracy and surface roughness that can increase production rate as well decrease basic cost. In the volume vs. volume ideal function mode, according to the data of elec-trode consumptive rate and material removal weight, it has shown that electrode consumptive rate is so fast that it is suitable for high production rate and low cost requirement. Time vs. weight mode can promote mate-rial removal weight, stable production, and production capability. There-fore, it is good to lower down product cost and shorten process develop-ment duration.
