A thermomechanical analysis of sticking-sliding zones at the tool-chip interface in dry high-speed machining of aluminium alloy A2024–T351: A hybrid Analytical-Fe model

Abstract : In high speed dry machining of aluminium alloy (A2024-T351), the tribological conditions at the tool-chip interface strongly affect the thermomechanical process of chip formation, the tool wear and the surface integrity. In order to contribute to the understanding of the effect of friction conditions, a hybrid Analytical-FE model is presented. The transient nonlinear thermal problem in the tool-chip-workpiece system is solved by using a Petrov-Galerkin finite element model. To illustrate the model results, the relationship between the local friction coefficient, in the sliding zone, and the apparent friction coefficient, which takes into account the whole tool-chip contact, is presented.
