Inconel 825 is a family of nickel (Ni)-chromium (Cr)-iron (Fe) alloy with added add-ons of copper (Cu), molybdenum (Mo), and titanium (Ti). In this paper, dry experiments are carried out on Inconel 825 alloy based on the designed L16 orthogonal array using the advanced coated cutting tool. The levels of turning parameters are varied at 70, 120, 170 and 220 m/min of turning speed, 0.1, 0.15, 0.2 and 0.25 mm/rev of feed rate and 0.3, 0.4, 0.5 and 0.6 mm of cutting depth. Cutting forces, surface roughness, and chip quality determination are considered as technological parameters. The factor effect on output responses is studied using responses surface 3D plots. Results of variance test and the Pareto chart shows that cutting depth and feed rate is the most substantial effect on all the responses followed by cutting speed. It also reveals that lower cutting speed, low feed rate along cutting depth resulted in lower cutting force and surface roughness. The chip macrograph reveals that distance between the helical increased by increasing the cutting speed and feed rate and decreasing the cutting depth and chips are formed short helical and serrated ribbon chips under different cutting parameters. © 2019 The Authors.
