Diamond공구에 의한 aluminium 합금의 초정밀 절삭가공에 관한 연구
A Study on the UItraprecision Cutting of Aluminium A11oy by the Diamond Tool ABSTRACT This paper presents the characteristics of surface roughness and cutting force in ultraprecision cutting of aluminium alloy using natural diamond tools whose edge radii are smaller than those of tools made of other materials. The feed rate and depth of engagement were set to be a micrometer order. After measuring the surface roughness of machined surface and cutting force for each cutting condition, the relations between the surface quality and its condition were investigated qualitatively. If the feed rate was under a certain limit, the machined surface quality was deteriorated unexpectedly. This is supposed to have happened due to vibration leading its condition to abnormal one. In a certain situation the machined surface roughness by a natural diamond tool was inferior to that made by a carbide tooI whose cutting edge radius is larger. This is supposed to be caused by not normal machining but burnishing effect. Key Words : Ultraprecision Machining(Cutting) ( 초정밀 가공), Diamond Too1(다이아몬드 공구)>
