Reduction of Forging Load by Applying Lateral Oscillation

The chapter investigates the application of lateral oscillation to reduce forging load during the upsetting process of pure aluminum billet. Experimental and numerical simulations were conducted to examine the effects of lateral oscillation on load reduction and workpiece deformation. The study found that lateral oscillation can reduce the upsetting load by up to 35% compared to conventional methods. The load reduction ratio was significantly influenced by the relative oscillating speed to the axial compressing speed. Additionally, the workpiece geometry after upsetting showed distinctive deformation patterns, with the compressed region extending in the oscillating direction and the surface profile changing to a concave shape at higher speed ratios. These findings offer valuable insights into optimizing the forging process for complex metal components, particularly in industries where weight reduction and enhanced material flow are crucial.
