Homogenization and Parametric Consequence of Warm Deep Drawing Process for 1050A Aluminum Alloy: Validation through FEA

In this present work, a statistical approach based on Taguchi Techniques and finite element analysis were adopted to determine the parametric consequence on the formability of cup using warm deep drawing process. The process parameters were thickness of blank, temperature, coefficient of friction and strain rate. The experimental results were validated using a finite element software namely D-FORM. The sheets used for the deep drawing process homogenized to improve the drawability of the cups. The thickness of sheet, temperature, coefficient of friction and strain rate would influence the effective stress. The major parameter which could influence the effective stress, height of the cup, damage in the cup were the thickness of sheet, strain rate, clearance, radius of the die and temperature. The homogenization at 5000C for 16 hours could improve the drawability of the cups.
