碩士 === 明志科技大學 === 機電工程研究所 === 96 === This paper contains two parts. The first part is to investigate the clip force and vibration properties of the holder of the auxiliary high-speed spindle in the machine tool. Using the finite element software ANSYS, the clip forces, contact stresses, von Mises stresses, natural frequencies and mode shapes are obtained for the holder design estimation. The advantages and disadvantages of the aluminum and steel holders are discussed. The second part of this paper is to obtain the optimal dimensions of the 5-axes CNC machine tool using finite element analyses and Taguchi method. The structural deformation, natural frequency and weight are used to estimate the machine tool performance. The rib thickness, rib interval and wall thickness are the experimental factors in the Taguchi method. The numerical result of the optimal design is compared with the original design. It is proved that the optimal design from the Taguchi method has good performance.
