A study of Pickup Lens manufacturing in diamond turing machine
초정밀가공기를 이용한 광 저장용 렌즈의 절삭특성
Abstract
The asphericals lenses are used as objective lens of optical pickup. To examine the design factor the sample product is made before manufacturing of injection mould of lens. The optimum cutting condition of PMMA lens sample with ultra precision SPDT, he main spindle sped, the depth of cut, the feedrate are found. The demanded surface roughness 10nm Ra, aspherical form error 0.5
