碩士 === 國立屏東科技大學 === 機械工程系所 === 105 === This study aimed to investigate the optimal parameter combinations by processing eccentric shafts using turning and milling complex machines as well as self-made fixture in turning and milling processes. First, the configuration of the experiment for processing the eccentric shafts was planned using the Taguchi orthogonal table, where spindle speed, feed rate, cutting depth and eccentricity were selected as the processing parameters. With each parameter having four levels, there were a total of 16 experiments. The eccentricity error of the eccentric shafts was measured following the experiments. Through the average analysis of the degree of influence of the most important processing parameters, we learned that, for turning, the optimal parameter combination for eccentricity included a spindle speed of 2200 rpm, a feed rate of 0.2 mm/rev, a cutting depth of 0.4 mm and an eccentric distance of 0.25 mm, while, in terms of milling, the optimal parameter combination for eccentricity included a spindle speed of 2600 rpm, a feed rate of 500 mm/min, a cutting depth of 0.3 mm and an eccentric distance of 0.5 mm. The processing parameters affecting the turning-based eccentric shaft in descending order of importance were spindle speed, cutting depth, eccentric distance, and feed rate, while those affecting the milling-based eccentric shaft in descending order of importance were cutting depth, spindle speed, eccentric distance, and feed rate. The analysis process and results of this study could serve as a reference for selecting optimal parameters for turning or milling eccentric shafts.
