A Study on The Surface Roughness Of Metal Workpieces Machined by Ion Sputtering

이온 스파터 가공에 의하 금속표면의 표면거칠기에 관한 연구

Since Ion sputter machining can perform removing processing in atom or molecule units in vacuum state, it has the merit that high precision processing is possible. In this study, therefore, the effect of incidence ion beam is certified to processing amount and surface roughness when longtimed processing is applied. As a result, processing amount is made almost constant with time and the best processing condition is achieved when the incidencial angle of ion is 55.deg.. In addition, processing time for the good surface roughness is different respectively to the quality of material and longtimed processing has some defect for achieving good surface roughness.

본 연구에서는 장시간 가공하는 경우 가공량과 가공물에 입사되는 이온 빔의 입사각도에 따라 이온 스파터 가공이 표면거칠기에 미치는 영향에 대해서 연구해 보았 다.
