In machining of aluminum and its alloys, since they have highly adhesive characteristics compared with steels, more effective lubrication is often necessary. This study proposes that oxygen-including compounds, such as esters and alcohols, are potential lubricants for MQL machining of aluminum alloys. This paper further investigates the influence of humidified air on their MQL cutting performance. The experimental facts demonstrated that specific alcohols presented the excellent anti-adhesive characteristics in MQL end milling and the combination of an ester and an alcohol could in some cases show the superior cutting performance to that of single ester or alcohol application. It was further found that humidified atmospheric air, compared with dry air, improved the anti-adhesive characteristics of the oxygen-including compounds.
