Abstract—Recently Oil Hardened Non Shrinkable (OHNS) steel finding many applications in Manufacturing parts like Shaft, Gears and Tooling due to their excellent Mechanical properties. The continuous development of carbide milling cutter and its coating technology are great concern with manufacturing Environment. Titanium Aluminum Nitrite coating play an important role in milling cutter to produce better surface finish and tool life with minimum cost. In this Experimental investigation of face milling operation of OHNS steel plates with different process parameters like spindle speed, feed rate and depth of cut and to find optimal machining conditions of minimum surface roughness (Ra).The experiments are designed and conducted based on Taguchi’s design of experiments using L9 orthogonal array and analyzed by ANOVA.
