Influence of Coating Material and Cutting Parameters on Surface Roughness and Material Removal Rate in Turning Process Using Taguchi Method

Abstract This paper presents the influence of cutting parameters (Coating material, Depth of cut, Feed rate, and Spindle speed) on material removal rate (MRR) and surface roughness of TiAlN/WC-C, TiAlN coated tool during CNC turning of AISI 1015 mild steel. Taguchi optimization method has been employed with L9 Orthogonal Array for maximization of MRR and minimization of surface roughness on Jober XL CNC lathe. It is observed that the coating material (TiAlN/WC-C) has significant influence in determining the output parameters. This study also determined a predictive equation for determining MRR and Surface roughness with a given set of parameters in CNC turning.
