Abstract

This This study aims to verify burr formation and to remove the burrs in micro-channel fabrication using micro-machining tools. The machining processes are combined with micro-milling and magnetic abrasive deburring for AISI316 stainless steel. Depending on the micro-milling conditions that are applied, burrs are formed around the side walls. Magnetic abrasive deburring is used to remove these burrs. AISI316 stainless steel is a nonferrous material and its magnetic flux density, which is an important parameter for efficient magnetic abrasive deburring, is low. To enhance this magnetic flux density, we design and build a magnetic array table. The effect of removing burrs is evaluated via SEM and a surface tester.

본 연구는 마이크로 머시닝을 적용한 유동채널가공에서 버의 발생과 제거에 관한 연구이다. AISI316 스테인리스강의 마이크로 유동채널가공은 마이크로 밀링과 자기 디버링을 결합하여 실시하였다. 먼저 마이크로 밀링으로 유동채널을 가공하였고, 가공조건에 따라 마이크로 채널주변에 미소 버가생성됨을 확인하였다. 미소 버를 제거하기 위해서 자기 디버링을 행하였다. AISI316 스테인리스강은 비자성체로 자기연마에 큰 영향을 미치는 자속밀도가 매우 낮은 금속이다. 본 연구에서는 공작물의 자속밀도를 향상시키기 위해서 자기 테이블을 개발하여 이를 자기연마 디버링에 적용하였고, 주사전자현미경(SEM)과 표면형상기로 자기 디버링에 의한 버의 제거효과를 측정하였다.
