2D-FEM SIMULATION OF THE ORTHOGONAL HIGH SPEED CUTTING PROCESS

Abstract

The description of cutting processes using FEM based simulations offers a lot of advantages compared to analytical models. In this paper the simulation of high speed orthogonal turning (HSC) of AISI 1045 steel using the commercial software DEFORM 2D is described. Additionally high speed turning experiments are conducted and analyzed. It is investigated whether the comparison of simulated and experimental results is permissible. Therefore, the input parameters of the simulation are evaluated. It is shown that for the modelling of the cutting process by FEM simulation several assumptions regarding the material properties have to be made. Despite these limitations the comparison of simulation and experiment shows good agreement. To enable this comparison a simulation routine for potentially endless continuous cutting simulations is presented.
