A two-dimensional finite element model of orthogonal cutting is developed with Abaqus/explicit software. An Arbitrary Lagrangian-Eulerian (ALE) formulation is used to predict chip formation, interfacial temperatures, chip-tool contact length, chip thickness, and cutting forces. This numerical model of orthogonal cutting is then validated by comparing these process variables to experimental and numerical results obtained by Filice et al. (2006) [1]. This model makes possible qualitative analysis of input parameters related to cutting process and frictional models. The interfacial law determined by Brocail et al (2010) [2] is implemented on this finite element model of machining and leads to improve numerical approaches of machining. Other interfacial law established by Ben Abdelali et al (2012) [3] is also implemented on the finite element model and compared with the first one. Results of this comparison show the absolute necessity to take into account the dependence of the pressure and the temperature in the implemented friction law
