It is essential to devise simple low cost system that will eradicate the use of mineral cutting fluid. Minimum quantity lubrication system with vegetable oil is suggested as an option for the dry and flood cutting. This paper focuses on the comparative study of the different cutting fluid based on the tool wear and tool life. Result showed MQL with vegetable oil system gave improved performance as that of mineral-based oil without affecting the ecological system. Keyword –tool life, tool wear, MQL, vegetable oil
