Deep drawing is a common metal forming process used to manufacture recessed threedimensional parts from flat sheet metals. The research in deep drawing has been generic over the last few decades and various aspects of this process have been investigated. The paper aims to review the following aspects of deep drawing process that affect the quality of the product, tooling life and process design...

In the current work, cup drawing experiments with laser assistance are presented where only selected areas of the work piece have been heated up. Since the strongest deformations occur at the outer circumference of the blank, only that area has been heated up by a defocused laser beam. Selective laser heating of the work pieces was performed by diode as well as Nd:YAG laser radiation. The formi...

This paper investigates the earing phenomenon in deep drawing of AA3105 aluminum alloy, experimentally and numerically. Earing defect is mainly attributed to the plastic anisotropy of sheet metal. In order to control such defect, predicting the evolution of ears in sheet metal forming analyses becomes indispensable. In this regard, the present study implements the advanced yield criterion BBC20...

Deep drawing process is one of the widely used methods in sheet-metal forming. With the deep drawing method, products of various geometrical shapes such as saucepans, tubes, perfume and soft drink cans can be obtained easily. Therefore, the optimization of the deep drawing process is very important for the industry. In conventional deep drawing method, no angle is given to the surfaces of die a...
