A study on the machining condition of diamond stylus using ion sputter machining
다이아몬드 촉침의 이온 스파터 가공조건에 관한 연구
Abstract
There are requirement of surface roughness in mechanical elements that has minute surface of several nm degree. When high precision surface roughness measurement is made with stylus type surface roughness measuring apparatus, measuring accuracy depend on the tip radius of diamond stylus. Therefore, ultra precision machining was accomplished using ion sputter machining in order to machining the stylus tip radius less than 0.5.mu.m, which is impossible through lapping machining. In this study, optimal machining condition for the ion sputter machining was obtained through the experiment under the various varing machinbing quantity and condition of diamond stylus. And as the result of applying this optimal condition, the good result was obtained that machining probability of stylus tip radius less than o.5.mu.m is 93%.
