Wet machining of Inconel 718 using standard coolant and aluminum oxide (Al₂O₃) nanofluid application to increase machining rate are compared in this work. Various parameters are adjusted during computer numeric control (CNC) turning of Inconel 718, and measurements are taken to determine the material removal rate (MRR). Al₂O₃ nanofluid was used as a novel flood coolant while cutting at varying speeds, feed rates, and depths. Samples machined using nanofluid (Group A) and samples machined using conventional coolant (Group B) made up the two groups. Samples machined using nanofluid (Group A) and samples machined using conventional coolant (Group B) made up the two groups. The sample size was calculated 16 per group and used Taguchi standard Design of Experiments L16. The volume of material removed per minute is calculated using weight loss due to machining, machining time, and material density data. The key parameters of depth of cut, adjusting the input variables of work angular velocity (speed) and rate of tool feeding resulted in 16 different permutations of weight loss and machining time. The machining rate (MRR) that was observed was compared. The application Al₂O₃ nanofluid significantly raised the mean MRR to 1110.8376 mm³/min than the use of conventional coolant (795.76 mm³/min). Sig. value was 0.02 and it is less than 0.05, so statistically significant difference between the observed results of two groups. This suggests that there is a discernible divide between the two sets of people. In CNC turning of Inconel 718, it was discovered that the unique use of Al₂O₃ nanofluid gave greater MRR than conventional coolant.
