..., for constant stock material removal volumes. For each case, the tool material volume worn away, as well as the corresponding volumetric wear profile evolution in terms of a set of geometric coefficients, is quantified—these are then related to the MRR. Further, the volumetric wear rate and the M-ratio (volume...

... Ti–6Al–4V. Additionally, the inferred dependency of wear rate on the cumulative wear offered a possible explanation for the common and sudden catastrophic tool failures when machining titanium alloys; a VTW predictive model was developed in this regard. Finally, the inverse dependence of the M-ratio...

..., such as the Taylor’s tool life model and its extensions. This assessment methodology is then validated through the simultaneous analysis and comparison of traditional flank wear and associated photomicrographs with volumetric wear and its evolution. Furthermore, the concept of the M-ratio and its derivatives...
