Abstract:
With the rapid development of micro/nano science and micro-electro-mechanical systems (MEMS) technology, the requirements for micro-parts are quietly increased. Micro-forming is a manufacturing method using plastic deformation for the production of parts having at least two dimensions in the sub-millimeter range. Micro-forming becomes an attractive option in the manufacturing of micro products with high efficiency, simple process, excellent properties and high accuracy because of its advantageous characteristics for mass production with low cost. The background, application and advantages of the micro-forming are presented. The state of the art in micro-forming is summarized from the viewpoint of size effect, novel micro-forming machine, forming processes and methods. Finally, the development trends of micro-forming technology with new materials, such as ultrafine-grained materials and bulk amorphous alloys, are discussed.
