Effect of Cutting Parameters with Dry and MQL Nano Fluids in Turning of EN-36 Steel

Abstract

Many exploration works did to limit cutting force, temperature, surface roughness and tool wear during turning process, yet in dry machining it is hard to limit these parameters straightforwardly, to limiting these parameters diverse lubricants have been utilized until now. In spite of the fact that there have been many research works on the thermal conductivity and lubricity of nano fluids with minimum quantity lubrication (MQL) in numerous fields and the investigation in regards to the utilization of cutting fluids with nanofluid particle during milling process of EN-36 steel is not done to the larger extent. In the current work, nanofluids were prepared by adding 6% volume and 8% volume of Al2O3 nano particles to the vegetable fluid independently, these nanofluids were utilized during milling process of EN-36 Steel and measured the parameters in dry machining and with MQL nanofluid lubricants. Experiments were conducted by utilizing the Taguchi approach and the outcomes were dissected utilizing analysis of variance (ANOVA). Experimental and predicted values were compared and analyzed. The analysis of the results revealed that the roughness, temperature, cutting force and tool wear in 8% volume of nanofluid with MQL were 0.1 μm, 44.16 °C, 280.46 N and 0.0031 mm respectively are significantly better than the dry machining and 6% volume of nanofluid with MQL performances. Finally, the established results concluded that the machining with 8% volume of nanofluid with MQL have improved the machining performance when compared with the dry milling process.
