Abstract : During the machining process, a significant quantity of heat energy is dissipated, which has an impact on tool life, surface finish, and dimensional accuracy. Cutting fluids are used as lubricants to overcome this drawback. However, these fluids rely heavily on petroleum oils, which are both hazardous and non-renewable. Thus, bio-lubricant is prepared from banana peel powder and used as alternative cutting fluids. Physicochemical properties of banana peel oil such as density, viscosity, fire point, pour point, and flash point are determined and compared with conventional cutting fluid (lathe oil). It is noted that it has improved characteristics and could be well suited as a lubricant. This bio-oil is mixed with various percentages of lathe oil (10, 15, and 20%) and utilized as a cutting fluid during lathe turning. The surface roughness, coefficient of friction, and wear scar diameter are determined. The use of a bio-oil blend reduces roughness and the average diameter of wear scars. The reduction is higher as the percentage of banana oil in blends is increased. It also improves the coefficient of friction, extending the tool’s life. The result showed that the prepared bio-oil could be used as a lubricant for machining operation. This bio-oil is more eco-friendly as compared to mineral oils which is a significant advantage.
