S1302-1-5 Effects of Oxygen-including Compounds on Cutting Performance in MQL Machining of Aluminum

Abstract

In machining of aluminum and its alloys, since they have highly adhesive characteristics, effective lubrication is often necessary to prevent their accumulative transfer on the tool and the resultant chip jamming. This study therefore proposes novel cutting fluids based on such chemical compounds including oxygen as ester, alcohol and acid. In particular, some specific alcohols have demonstrated the exceedingly high performance in tapping of aluminum compared with ordinary successful cutting fluids comprising extremely pressure additives. The study has further examined the performance of those oxygen-including compounds as a MQL fluid in near-dry machining.
