Abstract
This study examines the effects of applying lateral oscillation during compression. A circular cylindrical aluminum bar inserted in an upper and a lower die with fitting bores was radially extruded, and lateral oscillation was applied to the lower die. The finite element analysis predicted that the relative oscillating speed against the compressing speed can affect the load reduction. Experiments were conducted based on the numerical results, demonstrating a maximum load reduction of 35% compared with the case without oscillation. From the relevant measurement of the workpiece, the compressed region was reported to be slightly elongated in the oscillating direction.
