NUMERICAL ANALYSIS OF THE FRICTION CONDITIONS INFLUENCE ON THE METAL TUBES EXTRUSION PROCESS
The aim of this study is to realize a numerical modelling study of the metal tubes extrusion process with the purpose of understanding how the material flows in the die and respectively how the friction parameters influence the plastic deformation evolve. The initial semi-finished part 34CrMo4 steel is a 24 mm in diameter and 15 mm long bar and undergoes a 3D complex extrusion process in a die consisting of an inferior die and a punch.
