A Review of Deep Drawing Process and Interdependency of Its Parameters

Deep Drawing is a widely used sheet metal shape transformation process with material retention. From Automobile components to plumbing and sanitary ware, this process is used for mass production of industrial and domestic artifacts with the depth greater than corresponding diameter. Deep drawing process using a die-punch pair on a press induces radial stresses on flange region and compressive stresses on the center of a blank to provide a permanent shape change. The production quality and cost associated depend upon obtained thickness distribution and an accurate prediction of formability. This demands a coherent set of correlations between various parameters associated with deep drawing. This study reviews various theoretical and experimental attempts made to connect punching force, blank holding force, dome height, thickness of blank etc. with thickness distribution on final products. The focus is also drawn onto various modes of failures for different shapes of products and associated problems including creasing and wrinkling, crushing and cracking of sheet metal parts. Conclusions are drawn to suggest impact of isolated deviation of one or more parameters on the resulted product.
