Abstract
Minimum Quantity Lubrication (MQL) machining involves the application of a small quantity of lubricant being dispensed to the tool-workpiece interface. This paper describes the results of applying different MQL lubricant (synthetic ester and palm oil) to the high speed drilling of Ti-6Al-4V. Dry cutting conditions were also used for comparison. It was found that cutting under dry conditions resulted in the shortest tool life due to severe chipping. MQL was found beneficial to the measured factors such as tool life, thrust force, torque and temperature. In addition, the outstanding performance of palm oil in reducing the value of these factors could be attributed to its ability to form a thin film which promotes boundary lubrication during the machining process. This work shows that the palm oil can be selected as a viable alternative to synthetic ester for MQL lubricant.
