Abstract

This paper reports the results of an experimental works to investigate the effect of cutting parameters and machining conditions on surface integrity when finish turning Inconel 718, a highly corrosive resistant, nickel-based super alloy, under three cutting conditions (DRY, MQL 50 mL/h and MQL 100 mL/h). The microstructure analysis using SEM on the machined surface suggests that severe deformation took place, leading to microstructure alteration at sub surface level measuring from a few to several micron in thickness. Work hardening under the machined surface was evident from the micro-hardness measurements where higher hardness reading was measured near the surface. The results of this study show that MQL may possibly improve surface integrity characteristics.
