Effect of Turning Process Parameter on Surface Roughness using Inconel as a Material

Inconel 718 is nickel- based superalloy extensively used in aerospace industries, marine industries, steam turbine power plant, and nuclear reactor. Present work focuses on optimization of turning process parameters of Inconel 718 using taguchi optimization technique. Surface roughness was the response variable investigated. Experimental results indicate that proposed mathematical model suggested adequately describe performance indicator within the limits of factors that are being investigated. Tool is the most influencing factor on surface roughness followed by depth of cut, speed and feed.
