Implementation of ale method in modeling of high speed turning operations for hardened steel

This paper describes the use of ALE method in modeling of orthogonal high speed turning operations for hardened steel. The two formulation techniques namely the Lagrangian and the Eulerian has been used in the past by many researchers. Due to the various limitations of the two approaches, ALE method has been adopted for the orthogonal high speed turning operations. In this method, the chip separation is performed by the deformation of the workpiece and adaptive meshing capability of ABAQUS/Explicit. The whole chip formation procedure consists of two stages starts with the initial chip formation followed by chip growth. For comparison purpose, simulation is also performed with the Lagrangian model and the two models are compared with the experimental data. It has been found that ALE model results are in good agreement with the experimental ones as compared to the Lagrangian model.
