| Popis: | A finite element model is presented to address the limitations of classical models of burr formation in drilling. In this finite element model, 2D analysis is used to predict the temperature distribution and stress state in the workpiece. Material removal is simulated through the use of element death and continues until a failure condition is predicted. At the point of failure, the remaining material is bent out to form the burr. The FEA model is compared with previous "classical" models as well as experimental data for 2024 aluminum. |
