Abstract: The aim of this study is to improve cutting model with a view to drilling modelling. Consequently, the model has to take into account the wide range of variations for cutting speed and tool angles that are specific to drilling. Strain and strain rate description have been modified in order to be continuous in the primary and secondary shear zones. The experimental set-up and results analysis allows us to set forth the necessity to improve constitutive law for cutting applications.

Keywords: cutting models; analytical modelling; drilling; cutting speed; tool angles; strain rate.
