The purpose of this study is to compare the performance of conventional coolant and innovative ZnO nanofluid in a flood cooling environment while enhancing the economy and machining performance of Inconel 718 material in CNC turning. To determine the Material Removal Rate (MRR), CNC turning of Inconel 718 is performed using a variety of parameter settings and observations. With the novel flood coolant of ZnO Nanofluid, we machined at varying speeds, feed rates, and depths of cut. Group 1 was made composed of samples machined using nanofluid, while group 2 consisted of samples machined using traditional coolant. Pretest 80% g-power and 5% alpha was used for predicting the minimum samples required per for this investigation. There are 2 groups, 32 samples in total and each group has 16 samples. Both groups are evaluated to determine the optimal coolant for improving MRR. The mean MRR of Inconel 718 using conventional coolant (group 2) was 795.763 mm³/min, whereas the mean MRR while machining the work material with Novel ZnO nanofluid (group 1) was 1085.863 mm³/min. There is a statistically significant difference between the two groups because the t-test’s significant value was less than 0.001 and less than 0.05. During machining with Inconel 718 in CNC turning operations, novel ZnO nanofluid resulted in a greater MRR than the traditional coolant, according to an experimental investigation.
