A Study on the Development and Performance Evaluations for a Self-diagnostication Ultra-precision Lens Polishing Machine

자기 진단형 초정밀 렌즈 폴리싱기의 개발 및 성능 평가에 관한 연구

Spherical glass lenses are used in many optical industries. The curvature, eccentricity and height of a tool affect the surface roughness and curvature of lenses. The purpose of this study is the development and performance of a self-diagnostication ultra-precision lens polishing machine. In this paper, structure analysis is performed to reduce maximum displacement and to maintain outside the resonance region by CATIA V5. A spherical center setting gage is developed to increase accuracy of the manufactured lenses. The surface roughness, curvature and thickness of the manufactured lenses are measured and studied.
