NUMERICAL MODEL FOR DYNAMIC ANALYSIS OF TOOL AND WORKPIECE IN TURNING

In this paper is presented the dynamic response of the system tool-workpiece during turning operation by taking into account the regenerative effect. A new model based on the finite element methods was developed to establish the dynamic equation of the system. The tool was modelled by a beam while the dynamic effect of the non deformable elastically suspended workpiece was introduced by considering its displacements. The dynamic response of the entire system confirms the existence of the coupling between the tool and the workpiece. The simulations show the variations of the cutting forces around the static equilibrium and the effect of the vibratory behaviour on the profile of the workpiece during the raising operation.
