Investigations on the flank wear and modelling of the contact radius effect in turning of Ti6Al4V titanium alloy
Communication avec acte
Machining of difficult-to-cut materials like Ti6Al4V titanium alloy leads to significant flank wear on the cutting tool. In order to ensure the respect of final part specifications, flank wear has to be controlled. In literature, predictive models had been developed. However, these models can be enhanced by taking into account new parameters depending on the part geometry. This study deals with the analysis of the contact radius effect on flank wear. Results highlight that the contact radius favors the flank wear. Afterwards, a phenomenological model is proposed and improves flank wear modelling.
