박대광,이경일,고가진,김재열 한국정밀공학회 2016 International Journal of Precision Engineering and Vol.17 No.10
Active researches on milli-structures and micro-machines have been conducted in advanced countries, and micro-machining technology is one of the core items of the researches. The current technical backgrounds of micro-machining can be divided into semiconductor-based machining, such as lithography and etching, and conventional mechanical machining such as cutting, grinding, and electro-spark machining. The former can be limited due to their materials or thickness, and the latter, while having good productivity, suffer from a less-than superior finishing surface. Therefore, the cutting work could be reasonable in terms of superior productivity and a greater degree of freedom. Conventional ultra-high-precision cutting technology can be used for surface machining, but it has not yet been used to produce ultra-fine components. Therefore, researches on the preparation of ultra-highprecision micro-components in three-dimensional spaces with the milling technique using a single crystal diamond bite are underway. In this study, finite element analysis (FEA) was used to determine the safety and control performance of the micro-stage for the design of an elastic-hinge-type stage using a piezo-electric element.

Recently, Filter industry is point technology in machine kinds of a vehicle and various industry. Therefore, Republic of Korea need new technical development for 21th century of vehicle development occupying competitive power and technological high position. Therefore, This treatise made out this research to a filter of high efficiency and high effectiveness function, and refuse Way to add other material. By second, if long-lived and high efficient Filters are automated at all processes, Lives of various industry machines can be extended, may no be been resources waste, and natural environment may become clean. Therefore, this paper of focuses research and develops lor long-lived and high quality filters.
