Abstract

The minimum quantity lubrication (MQL) machining is capable to reduce the machining cost and cutting fluid consumption, while enhancing machining performance. However, the performance of MQL technique to reduce the machining temperature is still ineffective. In recent study, the use of supercritical carbon dioxide (SCCO₂) cooling technique has seen to give a very high effectiveness. This technique can reduce the machining temperature and cutting force subsequently prolong the tool life and surface quality. In this paper, the performance of SCCO₂ as a cutting fluids has been compared with MQL technique. The results showed that the SCCO₂ cooling technique was more effectiveness in reduce the cutting force and cutting temperature thus improve the surface roughnesss compare to the MQL technique
