摘要:One of the most important aspects in metal cutting is the determination of the effect of the cooling conditions on the cutting tool. In numerical models of metal cutting, these conditions are described by the convective heat transfer coefficient, which is usually determined empirically. The aim of this work is to numerically calculate the convective heat transfer coefficient of a turning process, using a hybrid FEM-CFD model. The model consisted of the coupling between a model in Abaqus/Explicit software for the thermo-mechanical part of the simulation, as well as a model in ANSYS CFX software for the simulation of the action of the cutting fluid on the cutting tool. After validation of the model was performed, the hybrid model was simulated for various conditions, i.e. for various cutting speeds and speeds of cut, thus obtaining valuable results regarding the applicability and efficiency of the proposed approach.
