This research presents an experimental investigation into the performance of four lubrication-cooling techniques (namely flooding, Minimum Quantity Lubrication with plain cutting fluid, an‎d nanofluids containing aluminum oxide an‎d copper oxide nanoparticles with an Ionic Liquid base) during the turning of Inconel 718 superalloy. Optimization of cutting parameters (lubricant type, feed rate, depth of cut, an‎d cutting speed) was performed using the Taguchi method, focusing on surface roughness. Statistical analysis results indicated that the lubricant type an‎d feed rate exerted the most significant statistical influence on surface roughness. The Ionic Liquid based nanofluid containing aluminum oxide nanoparticles delivered the best performance, yielding the lowest surface roughness value of approximately 1.58 micrometers. This result represents a reduction of approximately 48 percent compared to the conventional flooding method. This notable superiority is attributed to the nanofluidʹs capacity for improved tribological properties, the formation of a stable tribofilm, an‎d enhanced heat transfer, which effectively suppresses the formation of the Built-Up Edge. These findings offer efficient an‎d sustainable nanofluid-based machining strategies for superalloys.
