碩士 === 清雲科技大學 === 機械工程研究所 === 96 === The development in science and technology is fast now; the products are designed and manufactured by nanometer scale, it makes the micro-forming processes more important today. In micro-forming, the using of nontraditional technologies such as EDM, WEDG, PVD, PVC etc..., is rather normal. In this study, an electromagnetic micro-forming process is designed that the induced electromagnetic force will attract the ferromagnetic punch to contact the workpiece, and then forced the workpiece to deform. The experimental apparatus for the electromagnetic micro-forming process will be designed and manufactured. Meanwhile, the analysis of the micro-forming process by the dynamic FEM is examined. The relative experiment will proceed simultaneously. The sizes and shapes of the forming die and punch are discussed in details. Two solving methods for spring back phenomenon will be observed and assessed. These analytical results have been rather useful in the tools design, the products control and forming limit prediction. The most significant advantage is developing the precise analysis technology to suit for the future necessity of manufacturing processes in 3C industries.
