Abstract

This paper present the characteristics of micro- and meso-scale milling processes in which compressed cold air, minimum quantity lubrication (MQL) and $MoS_2$ nanofluid MQL are used. For process characterization, the microand meso-scale milling experiments are conducted using desktop meso-scale machine tool system and the surface roughness is measured. The experimental results show that the use of compressed chilly air and nanofluid MQL in the micro- and meso-scale milling processes is effective in improving the surface finish.

본 논문에서는 압축냉각공기, MQL 및 $MoS_2$ 나노유체 MQL 을 적용한 메소스케일 밀링의 가공 특성에 관한 실험적 연구를 수행하였다. 마이크로/메소 밀링 가공 실험 수행을 위하여 BLDC 스핀들과 DC 모터슬라이드를 장착한 데스크톱 크기의 3 자유도 메소 스케일 기계가공 시스템을 구현하였고, 가공 시편의 표면거칠기 측정 및 분석을 통해 가공성능 평가를 수행하였다. 실험을 통해 압축냉각공기, MQL 및 $MoS_2$ 나노유체 MQL 을 사용한 경우 건식가공에 비하여 표면거칠기가 향상되는 것을 발견하였으며 특히 $MoS_2$ 나노유체 MQL 과 압축냉각공기를 동시에 적용하였을 경우의 가공 표면거칠기가 가장 우수함을 확인하였다.
