Abstract
<p>To reduce axial forming load in upsetting process, upsetting process with cyclic torsion die motion was proposed. In the proposed upsetting process, cyclic torsion of torsional moment was simultaneously superposed with axial forming load during upsetting process. In this study, a cylindrical workpiece was twisted around the z-axis with an alternating amplitude angle of π/8 rad (22.5°) and a maximum rate of 0.05 rad/s (0.5 rpm) during upsetting with an axial compression speed of 0.1 mm/s. The maximum torsion frequency was 0.03 Hz. It was found that the axial forming load of the workpiece was reduced by approximately 5-40% in the forming conditions where torsion angle/axial stroke were larger than approximately 0.26 rad/mm.</p>
