Abstract: The aim of this research is the comparison of the load estimation methods by means of Upper Bound Analysis and a commercial FEM based programme called DEFORM-3D. For this purpose forward extrusion was chosen as forming method to manufacture a spur gear form. Two different die geometries were chosen for the forward extrusion; including straight tapered and cosine profiled dies. In the experimental study, Al 1070 was used as working material. Experiments using two sets of dies with spur gear form were performed, and the measured forming load results were compared with the predictions of the theoretical analyses by using DEFORM-3D and by using upper bound analysis. Experiments were carried out on the 150 metric ton hydraulic press with constant ram speed of 5 mm/sec. An acceptable agreement was obtained between the theoretical results and the experiments.
