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.]]>Bahatia, S.M., P.C. Pandey and H.S. Shan,197851201211Caldeirani Felho, J.,1998.1998.Chandrasekaran, H. and V.C.
