Lecture
This lecture covers the forces involved in metal forming processes such as extrusion and wire drawing. Topics include the extrusion pressure, dynamic cases of extrusion, specific energy of drawing and extrusion, and the contribution of friction on the container. The instructor explains the plasticity criterion, loss of adhesion between the blank and the die, and the impact of taper tension. The lecture also delves into the role of friction in metal forming and the limitations it imposes on the extrusion process.
