Inconel 718 is a family of nickel-based superalloy. Dry experiments are carried out based on L16 orthogonal array using advanced coated cutting tool. The factor effects on turning forces, surface roughness, and flank wear are studied using response surface 3D plots. It reveals that higher cutting speed, low feed rate along cutting depth resulted in lower cutting force and surface roughness but low cutting speed for tool wear. Using desirability function approach, the optimal parameter is determined as feed rate of 0.1 mm/rev, cutting speed of 70 m/min, and 0.5 mm depth of cut. Using SEM, abrasive wear along with welding of workpiece material is found on the wedge of cutting insert. At the end of tool life, the obtained surface is about 0.479 µm at 4 min. © 2019, Springer Nature Singapore Pte Ltd.
