ANALYSIS OF DEEP DRAWING PROCESS FOR VARIOUS PARAMETERS USING FINITE ELEMENT ANALYSIS

The main objective of this paper is to find the most effective parameters in deep drawing process to produce a cup of required shape and size. Limit Drawing Ratio is one of the parameters that indicate the drawability of material. It is defined as the ratio of blank diameter to punch diameter at the onset of tearing. Deep drawing products in modern industries usually have a complicated shape, so these have to undergo several successive operations to obtain a final desired shape. In this work the effect of various parameters like die and punch corner radii, clearance, friction coefficient between die and punch, punch diameter on limit drawing ratio is investigated and presented by using an explicit finite element code LS-DYNA 3D.
