Abstract:
The present invention relates to a method of machining a metal workpiece with a coated cutting tool insert comprising a cemented carbide body and a coating deposited as monolayer(s) or as multiple and/or alternating layers. The coating has a total thickness of 25-75 μm and the machining is performed at a cutting speed of >600 m/min, preferably 800-1500 m/min. The invention also relates to a coated cutting tool useful for such machining operation.
