Rapid prototyping technologies have been widely used to reduce the development cost of new products. Manufacturing industries are nowadays characterized by the flexibility and complexity of products. This to due to the rapid development of manufacturing technology and diverse needs of customers. In this paper, the best burning out and casting condition for getting casting product of resin pattern(photopolymer) have been examined experimentally. In generally, the burning out and casting conditions have effect on the casting products. Using the direct casting. we directly producted the jewelry. And in this paper, we used only gypsum. Many study of casting for resin have been used to dental investment. A dental investment is good for resin casting. but dental investment is too hard and not useful on the jewelry casting. Therefore we need to find the way of resin casting by gypsum.

To obtain the surface roughness with nano order, we need a ultra-precision machine, cutting condition, and materials. In this paper, the cutting condition for getting nano order smooth surface of core have been examined experimentally by the ultra-precision machine and diamond wheels. The effects of the cutting velocity, the feed rate and depth of cut on the surface roughness were studied. And also, the surface roughness was measured by the Form Talysurf series PGI 840. The champion data of developed core was surface roughness Rmax 24.6nm, figure accuracy Rmax 68.9nm.

The present study deals with polishing machining of diamond for jewelry using developed automatic polishing machine that can cut diamond to have 58 facets in a brilliant cutting which has been hardly achieved by a conventional manually operating polishing machine. Upon the 3-dimensional Sarin M/C test and analysis on the machined diamond by the developed automatic polishing machine its proportion and finishing turned out to be better than the machined diamond by the conventional manually operating polishing machine.

The ultra-precision cutting is a key technique for the manufacture of optical components such as aluminium mirrors, electroless nickel mirror, plastic mirror in a variety of advanced science and technology applications. The paper presents experimental results of ultra-precision diamond turning of electro less nickel materials. In general, the cutting condition such as feed rate and depth of cut, have effect on the surface roughness in ultra-precision diamond turning. To obtain an optimal cutting condition, we studied the effect of the cutting speed, the tool length, the tool nose radius, the feed rate and depth of cut on the surface roughness. So, the relationship of the surface roughness and cutting condition has been clarified. From the experimental results, the machined surface roughnesses were obtained less than 1㎚ rms.

The object of this paper is to find factors affecting the form accuracy in ultra-precision turning. Now, Ultra-precision machining has been applied for optical elements and lens. Those elements are required machining form accuracy of nano scale. In order to obtain machining form accuracy of nano scale, we have to find various factors affecting the form accuracy. From the experimentation, the effects of the chucking, cutting condition, centering, production direction of material were calculated and discussed by using workpiece's profiles.

The R&D investment of Korean government has been concentrated into 6T areas-IT(Information Technology), BT(BIO-Technology), NT(Nano Technology), ET(Environment & Energy Technology), ST(Space Technology) and CT(Culture & Contents Technology) - for a couple of years By this selection and concentration strategy, patent applica-tions are on an increasing trend m these areas. This paper examined the trends of patent application in 6T areas To do this, this paper classified each technology area into the detail technology area with the valid number of patent applications According to the result, the analysis data will be used to make R&D bridget appropriation of the government
