Inconel 718 is a heat-resistant Ni-based superalloy widely used, particularly, in aircraft and aero-engineering applications. It has poor machinability due to its unique thermal mechanical properties. For this reason, studies have been carried out from past present improve the of Nickel-based (Ni) alloys. Further improvement can be achieved by applying hybrid multi-objective optimization strategies ensure that cutting parameters cooling/lubrication are also adjusted effectively. That why, research, optimized under various sustainable lubricating environments i.e., dry medium, minimum quantity lubrication (MQL), nano-MQL, cryogenic conditions at different machining during end-milling process. Subsequently, analysis variance (ANOVA) approach was implanted apprehend impact each parameter. Finally, optimize environments, two advanced algorithms (non-dominated sorting genetic algorithm II (NSGA-II) Teaching-learning-based (TLBO) approach) were introduced. As result, both methods demonstrated remarkable efficiency machine response prediction. Both methodologies demonstrate speed 90 m/min, feed rate 0.05 mm/rev, CO2 snow optimal circumstances for minimizing responses milling 718.
