NUMERICAL ANALYSIS OF THE INFLUENCE OF LUBRICATION CONDITIONS ON THE FILLING PATTERN IN A COMPLEX PROCESS OF EXTRUDING PARTICULAR HIGH-MELTING MATERIALS

In this paper, the process of extrusion was analyzed numerically for a axisymmetric forging model where there is a complex material flow diagram (Fig. 1a). The analysis was performed assuming a different stoke slenderness ratio so you can control how to fill the die impression (direct extrusion, in direct and side - Fig. 1b)-d), using lubricants with different values of friction factor.
