Performance of TiCN and TiAlN tools in machining hardened steel under dry, wet and minimum fluid application

In this work, an experimental study has been carried out on the comparative performance of TiCN and TiAlN coated tools in machining of AISI 4340 hardened steel under dry, wet and minimum fluid application conditions and the analysis of results are presented. Cutting force, cutting temperature, surface finish and flank wear are compared in all the cases to understand the performance. Then, the relative influences of the machining and the minimum fluid application parameters on the machining performance of tools have been analysed and presented in this paper. © 2008, Inderscience Publishers.
