碩士 === 國立成功大學 === 機械工程學系 === 90 === Multi-axis machining is one of the important processes in modern precision manufacturing. For the machining of complex surfaces, it is very convenient to use multi-axis machining due to the advantages of high degree of freedom, short machining time and high precision. However, there are restrictions of the machine tools configurations so that the factories cannot machine complex surfaces successfully. The analysis and evaluation of the surfaces to be machined are the basis of the configuration selection of the machine tools. Adapting visibility map and fuzzy clustering, a method for machine tool axis selection was developed. In the developed method, the various configurations of machines was analyzed, the surface being machined was divided into several sub-surfaces. Then according to the above, the optimized machine, which has minimum number of axes for various configurations of machines, were obtained. With the optimized machine, we used the UG® software to generate cutter location file and verified the proposed method of the configuration selection of machine tool using visibility map. In this research, with the proposed machine tool axis selection method, the system is more completed and suitable for the engineers to substitute traditional trial-and-error method with more objective ones. The software, which was written with by Microsoft Visual C++ 6.0®, enables to analyze the CAD model of the product before workpiece being machined and to suggest the appropriate number of the axes and configurations of machine according to the characteristics of the surface.
