Crater wear of TiN-coated hob.
It is well known that the life of TiN-coated hob becomes tremendously longer than that of non-coated hob. But even a TiN-coated hob, its rake surface must be resharpend when it was worn out. And then TiN-coating on rake surface is removed but only on flank surface. And TiN-coating on flank surface is still effective to decrease the flank wear.

A study on the crater wear mechanism of cermet tools.
The purpose of this paper is to clarify the wear mechanism at high cutting speed where mutual diffusion at interface comes to active.The relation between the crater wear rate and the condition of diffusion layer by cutting test and dynamic diffusion test, for reference, was investigated and discussed.

Development and implementation of crater and flank tool wear model for hard turning simulations [PDF]
Abstract This paper concerns the tool wear in hard turning of AISI 52100 hardened steel by means of PCBN tools. The purposes of this work are the development of a tool wear model and its implementation in a FEM-based procedure for predicting crater and flank wear progression during machining operations for studying the influence of ...
