Abstract—Metalworking fluid (MWF) is commonly used to reduce wear and friction, which in turn improves the productivity and quality of the components. However, theusage of conventional MWF made frommineral oil causes negative effects to the ecology and human health. Therefore, it is desirable to formulate sustainable MWFs as an alternative to petroleum-based oils. The crude Mahua oil (CMO) with various compositions with synthetic esters as per ASTM STD is formed and modified Mahuaoil (MMOs) were tested in the test specimens. The orthogonal cutting process carried out and the lubricants were supplied by using minimum quantity lubrication (MQL) technique. It was observed that theMMO exhibited an outstanding performance in terms of wear, friction and surface finish when compared to commercial syntheticester (SE). This works showed that MMO is a viable replacement for synthetic ester(SE) as a metal working fluid.

I. INTRODUCTION
Various kind of metalworking fluids (MWFs) are used for all machining operations. The sources of these fluids are from mineral oil-based, vegetable oil-based and synthetic oils based. The bio-based oil from vegetables oil has high biodegradation percentage and gives better lubrication performances in terms of physical and tribological behavior.
It was estimated that 52% of MWF is used for the machining purposein worldwide. The important function of MWF is to dissipate heat generated at the tool-chip interface in machining operation. Also, the MWF provides a thin layer between two contact surfaces to reduce wear and friction. The adequate lubrication effect of the MWF reduces the amount of required coolant to absorb the heat generated during the machining process.
Therefore, less friction occurred at the machining zone that contributes reducingthe energy consumption. The use of MWF from bio-based oil is due to the increasing concern about eco-friendly sustainable element in the machining process to avoid harmful effluents.
