A Low-Cost Bio-Coolants Production and Characterization

Abstract

Cutting fluids plays a significant role in machining operations. They are widely used during metal removal operations to remove the heat from the workplace and at the same time provide better lubrication. Currently petroleum derived cutting fluids are widely use due to availability and marginally low cost. However, their applications lead to increase in environmental pollution and cause health hazards to the workers. Therefore, bio-cutting fluids are gaining significant importance as a substitute to the conventional cutting fluids. In this study three different low cost oils such as waste cooking oil, waste engine oil and waste transformer oil are chosen and their tribological properties are evaluated. From the experimental results it is observed that waste cooking oil tribological properties shows better than the other oils.
