主　　题：Milling (machining) 

摘      要：This comparative experimental study aims to improve machinability in terms of machining rate by novelly applying SiO2 nanofluid in the palace of conventional coolant for CNC end milling of Inconel 706. Two groups considered in this study are SiO2 nanofluid (CN) and Conventional Coolant (CC) based wet machining of Inconel 706 work material. The carbide end mill cutter of four flute, square end type used. Nanofluid with SiO2 concentration 4 wt% with less 5 nm sized particles considered. Sample size calculated 16 per group with G-power 80 % and alpha 0.05 settings. The key factors of cutting velocity, cutter feed rate, and depth of cut are varied by four levels. Material Removal Rate was calculated from the experimental observations and compared group wise in SPSS software. The test result shows a significance value of 0.015 (p less than 0.05), which reveals that observed results are significant. Novel application of SiO2 nanofluid in CNC end milling of Inconel 706 yielded 44.71 % higher material removal rate than conventional coolant. © 2023
