Abstract: With the goal of manufacturing meso-scale components and based on the traditional manufacturing technology, the concept and its connotation of precise and microminiature manufacturing technology are proposed. Firstly, precise and microminiature NC turn-milling technology is proposed, and further, technics and characters of complete manufacturing of microminiature components are studied based on the micro-miniature turn-milling MC. Secondly, high frequency group pulse (HGP) ECM manufacturing technology with high-power is proposed for microminiature metal components of fuzes. Thirdly, simulation theory and modeling method based on the manufacturing characters are proposed, and some examples are introduced. Last, computer aided microscope measuring tech-nology based on the technics matching principal is proposed, and improvements of some key technologies are introduced.

Key words: Complete manufacturing, Coupling, ECM, High frequency group pulse (HGP), Manufacturing character, Meso-scale, Microscope measurement, Precise and microminiature manufacturing, Turn-milling
