Abstract

The performance of the PVD coated carbide insert with micro-holes is experimentally compared with that of the conventional inserts while machining Inconel 718 under Dry and MQL condition (Canola Oil, 0.25% Gr with Canola Oil). The machining performance of textured tool is found to be relatively good when compared to untextured tool in terms of the cutting force, surface roughness, flank wear and crater wear occurred on the cutting inserts. It is being inferred that Canola oil with 0.25% Gr-nanoparticle has improved the cutting force by 17.39%, decreased the flank wear and surface roughness by 20% and 36.23% respectively while machining with the textured tool.
