MQL machining has been recognized as one of the representative environmentally friendly manufacturing operations. It is particularly successful in machining of steels, and synthetic biodegradable esters play a significant role as an effective cutting fluid with a very small amount. In recent years, the application of aluminum and its alloys to automotive part materials is growing. In machining of them, since they have highly adhesive characteristics compared with steels, more effective lubrication is often necessary. This paper therefore investigates the cutting perfonnance of synthetic polyol esters in connection with their molecular structures. The experimental facts demonstrate the importance of both lubricating action and permeation ability of the esters in achieving preferable MQL machining of aluminum.
