Recently, the trends of TFT-LCD are large scale and thin thickness, so, the demands of Light Guide Panel(LGP) which is able to substitute for prism sheets are appeared. Functions of LGP obtaining polarization of light of the prism sheet as well as the incidence and reflection of light are demanded. This prismless type LGP to complete functions of the existing LGP and polarization at once must be supported by micro machining technology of LGP surface. In this research, we have used the STAMPER method for the mass product and In-Line process, and the optimized conditions are established by analyzing the cutting force and conditions according to the material and processing properties when the prismless type LGP mold is fabricated. Parameters of the cutting condition were the workpiece and cutting depth.

1981년 10월 설립하여 2001년 코스닥 등록을 한 레이젠 주식회사(대표·태성길)는 자체의 금형기술과 사출성형의 Know-how를 접목하여 BLU 기술 진보에 핵심 역할을 해오고 있다. 2000년 국내 최초로 무인쇄도광판 및 초박형 도광판 개발에 성공하여 BLU의 기술을 한 단계 높임은 물론, 경쟁사에 비해 제품력이 우수한 프리즘 도광판을 개발, 지난해 말부터 양산에 들어가는 등 기술력에서 당당히 인정받고 있다. 이러한 장점을 바탕으로 현재 국내 납품처 다변화와 해외시장 진출을 적극 모색 중이다

Recently, trends of TFT-LCD toward larger scale and thinner thickness continue. so, demands of Light Guide Panel (LGP) which is to substitute for prism sheet are appeared. Functions of LGP obtaining polarization of light of the prism sheet as well as the incidence and reflection of light are demanded. This prism type LGP to complete functions of the existing LGP and polarization at once must be supported by micro machining technology of LGP surface. In this research, the machining characteristics of the various materials were analysed by shaping using V-shaped single crystal diamond tool. The characteristics are machined surface, machining force due to the variation of cutting depth. Used specimens are engineering materials, which are 6:4 brass, oxygen-free copper, Al6061, PC, PMMA. The FFT analysis of the measured cutting force was conducted. The cutting characteristics were analyzed and the optimum cutting conditions with materials were established.
