Machinability and parametric optimization of Inconel 600 using Taguchi-Desirability analysis under dry environment 2019-28-0068

Inconel 600 is a face-centered cubic structure and nickel-chromium alloy. Alloy 600 has good resistance to oxidation, corrosion resistant, excellent mechanical properties and good creep rupture strength at higher temperature. Alloy 600 is used in chemical and food processing, heat treating, phenol condensers, soap manufacture, vegetable, and fatty acid vessels. In this context, the present paper investigates the machinability characteristics of Alloy 600 under dry environment. Also, the parametric effect of cutting speed, feed rate and cutting depth on the force, surface roughness and tool wear are carried out using 3-Dimensional surface and 1-Dimensional plots. The optimal parameters are determined systematically based on Taguchi-desirability analysis with turned with TiAlN coated carbide insert. From the graphical analysis of collected data, the low rate of feed and moderate cutting for roughness and cutting force and average feed rate for tool wear with low cutting depth. Probability test at 95% confidence reveals the residual of machining data falls reasonably on a straight line and can be taken for factor optimization. Variance test reveals that the cutting depth (68.34%) has the highest influence on responses. Optical examination shows abrasive wear, and notch wear is tool to wear styles at investigated machining parameters. Chips geometries are found to be minimized at cutting speed in higher-level, feed rate and cutting depth in lower-level at the studied parameters.
