Numerical and Experimental Study on Deep Drawing Process for AA2024-T4Sheet
Deep drawing is an important process for forming sheet metal parts. It depends on many parameters regarding the tool design, process conditions and material parameters. In this work, a series of simulations to determine the effect of punch nose radius on maximum drawing height, thickness distribution and drawing force during deep drawing process of a cylindrical cup are using finite element based DEFORM-2D software. The validity occurred through the comparison between simulation and experimental results. The increasing in the punch nose radius could improve the sheet formability was found, and forming the limited formability of the 2024-T4 aluminum sheets.
