Capabilities of cermets tools for high speed machining of austenitic stainless steel
Cermets tools have very high hot hardness together with a low coefficient of friction, which facilitates machining at high speeds. In the present work cermet tools coated with titanium nitride were used to turn austenitic stainless steel at speeds between 300 and 700 m min-1. Feed rates were varied...
