| Popis: | Residual stress is the most critical criteria of surface integrity affecting the fatigue life of manufactured components. Thermal, mechanical, and metallurgical effects generated during a machining process can cause this failure. In order to study this phenomenon, several simulation methods have been proposed in the literature, each with specific capabilities and accuracies. However, for a fundamental understanding, a new 3D numerical model is developed using a mixed approach that combines experimental data with numerical FEM model. This approach consists of replacing tool and chip formation with thermo-mechanical loadings equivalent to the tool action. The thermo-mechanical loadings move around the external surface of the workpiece and along the longitudinal direction in order to take into account the interactions between revolutions. It has been noted that the steady state was reached within three revolutions. |
