Cutting fluids are popularly used to reduce the friction and associated effects in machining. However, due to the hazardous effects of these fluids on the workers' health and ecology, their usage is often discouraged. This has given rise to the concept of Minimum Quantity Lubrication (MQL). The present work focuses on preparation and testing of vegetable oil-based micro and nano cutting fluids in MQL. Two different solid lubricants- boric acid (H3BO3) and molybdenum disulphide (MoS2) were dispersed in the coconut oil as micro/nano particles. The formulated fluids were used in machining to study the performance. It was observed that nanofluids out performed microfluids at high cutting speeds, but at lower speeds, the performance was identical. Optimization and economic analysis was carried out to study the viability of the fluids. It was found that, though performance of the nanofluids is better, microfluids are more economical. The results can be used to choose the cutting fluid based on the required performance of the lubricant.
