碩士 === 國立成功大學 === 機械工程學系碩博士班 === 96 === The configuration of the multi-task machine tool influences the manufacturability of the product during surface machining; therefore, choosing correct configuration is an important task. Traditional methods of choosing the configuration of multi-task machine tool for surface machining depend on the experiences of manufacturing engineers. Because the multi-task machine tools have become more complex especially for turn-mill machines, it is not enough for engineers to use their own experiences to make the configuration selection. If the experience rule cannot work, it causes the production delay and the cost increase. In order to assist the engineers to select the multi-task machine tool configuration more accurately, this study develops a manufacturability evaluation system to evaluate the required rotating angle and linear traverse range for the mill-turn machine tools for a given workpiece geometry. In this research, the vector analysis is used for analyzing surface data points of the mill-turn part, the geometric features can be classified into three categories. The necessary rotating angle and traverse range of the plane face and symmetric surface are evaluated by vector analysis. The necessary rotating angle and traverse range of free surface are evaluated by visibility cone and tool orientation of turn-mill machine. Above-mentioned methods are integrated into to the manufacturability preliminary evaluation rules which be proposed in this thesis. Finally, taking three different part as examples, the manufacturability preliminary evaluation is verified by the simulation results generated from a commercial software.
