Comparing Material Removal Rate in CNC Turning of Inconel 718 Using Silicon Dioxide Nanofluid with Conventional Coolant

E.L. Yaswanth and R. Saravanan

Abstract

In this study, the results of computer numerical control (CNC) turning operations on Inconel 718 are compared utilizing both conventional coolant and a silicon dioxide (SiO2) nanofluid for flood cooling. CNC turning of the Inconel 718 was done with different settings of parameters and the observations made for calculating the material removal rate (MRR). The inputs parameters of speed, tool feed and depth of cut, were varied and machined with the flood coolant of SiO2 nanofluid. Machining samples with use of nanofluid was group 1 and machined with conventional coolant was group 2. There were16 samples per group total 32 samples were tested. Pre-test G-power 80% was used in sample size prediction. Both groups are compared for finding the best coolant to improve machining performance in terms of MRR. The MRR of the SiO2 nanofluid (group 1) was 1285.146 mm3/min, whereas the mean MRR of machining the material of Inconel 718 with conventional coolant (group 2) was 795.763 mm3/min. The significance p-value of this research study was 0.016 and it is less than 0.05. So statistically significant difference between the observed results of two groups. After conducting an experimental study, Machining with SiO2 nanofluid resulted in higher MRR than the practice of machining with the conventional coolant in CNC.
