Abstract: This study discusses about behavior of cutting tools in term of tool wear, tool life and surface roughness integrity when machining of nickel based alloys 242. Experimental tests were conducted using four different cutting tool materials under wet condition. They are TiAlN, TiCN/TiN, TiAlN/TiN (PVD) and TiCN/Al2O3 (CVD). Tool failure modes and wear mechanism for all cutting tools were examined at various cutting parameters. Flank wear was found to be the predominant tool wear for the four types of cutting tools especially with CVD tools. Coating is observed to be delaminated as main phenomena on all cutting tools surfaces. The obtained results have indicated that PVD cutting tools perform better than CVD cutting tools. The thickness of coating layers for CVD is thicker than PVD. Finite Element Analysis (FEA) is used to support this study in term of analysis of cutting tool deformation and cutting temperature.
