Abstract: The existing forming press uses a hydraulic actuator and high powered mechanical actuator, therefore occupying a large space because of its size. This type of system is inefficient for manufacturing micro size and precision products. As forming components are small in size, forming equipment must also be small in size because the forming die and load must be small. The micro forming manufacturing system is an ultra precision forming equipment the size of several micros to millimeters and precision of sub-micro to micrometer. This micro forming manufacturing system has the advantage of minimization in manipulating distance and working space. As equipment and tools become smaller in size, minute inertia force and high natural frequency can be obtained. Therefore, high precision forming performance can be obtained. This allows the factory to quickly provide the customer with goods because the manufacturing system and process are reduced. To construct a micro manufacturing system, many technologies are necessary such as high stiffness frame, high precision actuating part, structural analysis, high precision tools and system control. In this paper Research development about a micro metal forming manufacturing system has been developed. To coincide with the purpose to be more practical, we set the development of the equipment including micro deep drawing, micro punching and micro restriking process to the goal. To achieve this goal, the miniaturized micro metal forming manufacturing system is designed and made with miniaturized size system. A micro deep drawing process and system dynamic characteristic experiments are researched using this miniaturized micro forming system. A micro deep drawing experiment is performed using micro thin foil materials (Al-1100, SUS-304). If this miniaturized micro forming technology is used, efficient material practical use in the micro forming field which uses the micro metal thin foil is possible.

Abstract: The micro metal forming manufacturing system is essentially an ultra precision forming press that can manufacture various micro scale products from metal thin foil and bulk material. In this paper, the micro metal forming manufacturing system has been developed using a micro servo motor. A micro forming system has been developed in Japan with a micro press that is limited to the single forming process. However, a press with a multi forming process is needed and we set about performing research and development of assorted equipment, including investigation into micro deep drawing and the micro punching process. In order to achieve this goal, exploration into the micro forming process as related to the multi forming process must be preceded first. Material selection and analysis of the micro forming process are accomplished in this paper, and the basis research as to how to make the actual system is accomplished.
