Description

The performance of PVD-coated carbide cutting tools is influenced by their residual stress state, where coating and substrate subsurface have to be considered. The substrate stress is the result of different impacts caused by pre-coating processes and the PVD-coating itself. This presentation demonstrates the significance of residual stress in coating and substrate as well as the influence of each step of a conventional commercial process chain on the respective residual stress state for the manufacture of PVD-coated carbide cutting tools. Alterations of the process chain for tool micro geometry preparation by laser beam removal are considered.
