Formability Analysis at Different Friction Conditions in Axis-Symmetric Deep Drawing Process

In this paper FEA simulations are carried out for axis-symmetric deep drawing of usibore 1500 boron steel to examine effect of friction coefficient on the product quality. Usibore 1500 steel has extensively been used in manufacturing automobile body parts. Mechanical properties of usibore 1500 steel have been taken from published literature. Thickness distribution, VonMises stress and FLD curves have been studied for analysing the effect of friction. Thickness variation is one of the easy ways to check the quality of product. The results show that as coefficient of friction coefficient lowers, thickness distribution and quality of product improve. Moreover Von-Mises stresses also get reduced at lower friction. Also improved FLD curve obtained at lower friction value that indicates formability improvement.
