Numerical Simulation of the Deep Stamping Process

Resumo

The process of stamping is largely used when manufacturing a variety of structural and mechanical
components, composed basically of a die, a punch, and a blank holder. The CAE finite elements software,
Abaqus, allows the modeling, simulation, and analysis of the stamping process thus showing the influence the
punch displacement speed has over the maximum stress in the material. By the end of the analysis, including mesh
convergence studies, it is easy to observe that greater speeds result in greater stress levels of the workpiece and
larger deformations of its intended geometry. The study found that optimal punch speed levels for manufacturing
small aluminum cups lie between ranges of 40 to 60 mm/s.
