Abstract
Cutting tool life is reduced remarkably in machining steel with High speed steel (HSS) tools at high cutting speeds and feed rates. Due to poor cutting characteristics with the uncoated HSS tool, tool life is short and good surface finfish cannot be obtained in many cases. Therefore, the cutting characteristics can be improved by using Physical Vapour Deposition (PVD) coated cutting tool. In the present study, HSS single point cutting tool was coated with TiN, AlCrN and TiAlN by PVD method (Derlikon Blazer Ltd.).The cutting characteristics of TiN, AlCrN and TiAlN coated tools are investigated by measuring cutting force and hardness.
