A Study on the Precision Machining Characteristics of Aluminium 7075 and Silicon using Ultra-precision Turning Machine

초정밀 선반을 사용한 알루미늄 7075와 실리콘의 초정밀가공 특성연구

This study aims to find the optimal cutting conditions, when are nonferrous metals(aluminum and silicon) are machined with diamond tool of diamond turning machine. Diamond turning machine has been widely used in manufacturing optical reflectors of nonferrous metals. Such as aluminium and copper are easy to be machined because of their proper ductility. But optical crystals being discussed here are characterized by their high brittleness which makes it difficult to obtain high quality optical surfaces on them. The purpose of this study is to find the optimum machining conditions for ductile cutting of silicon and aluminium.
