With consideration of existing rolling machine and stock, the roll diameter is determined as 600 mm, the billet is φ 40mm (d0), material of work piece is AISI 1045.
When the stretching zone starts with both wedges, axial deformation dominates as four declining tool surfaces from double wedges stretch the work piece material, radial and axial plastic flow of the work piece material is accompanied by a circumferential component, as a result, the metal flow in the stretching zone becomes spiral in nature as the work piece rotates.
