“…It was observed that proper selection of material plays a significant role in the successful deep drawing of a component. Gao et al 20 investigated the influence of material parameters such as yield stress, hardening exponent and elastic modulus on deep drawing of a thin-walled hemispheric surface part by developing a three-dimensional FE model. It was observed that the effect of hardening exponent, yield stress, equivalent strain and punch force had more influence on thickness variation.…”

There are various processes practiced in a market for manufacturing axisymmetrical cup with significant forming depth among which deep drawing process is most prompt. The deep drawing process is a forming process with ongoing interest which will have a major impact on industries in coming years. This article focuses on the current status and potential of future development of technology in the deep drawing process. First, it describes various types of approaches and techniques used in the deep drawing of different materials. This is followed by brief reviews of advantages and limitations of these technologies with its application in industries. The details of these technologies are just referred rather than explaining in detail. The further part of this article focuses on advanced methods for predicting defects like thinning, wrinkling and spring-back in deep drawing process which are mostly responsible for rejection of the components. The opportunity in the development of flexibility in deep drawing process is covered with an observed barrier in the prediction of defects such as thinning, wrinkling and spring-back. The obtained evidence indicates that deep drawing process may not be applicable for all materials, but represents an excellent opportunity in the drawing of multilayer metal and composite material sheets to complex shapes.

During the process of deep drawing of cylindrical thin-walled products from aluminum sheets, the occurrence of product defects in the form of breaking the material continuity is observed. This has a very large impact on the efficiency of production lines and the number of generated scraps. The number of defects depends on many factors, including the material and the process properties. Because the problem appears after changing one material to another, while the process parameters do not change, it was assumed that the material has the main influence on the number of defects. To reduce the number of defects, a tool is needed to predict threats to the process. Decision tree models were used for this purpose. Using the tree interaction algorithms, the influence of the chemical composition and strength parameters of the 3xxx series aluminum alloy on the number of generated defects was investigated. Increased Silicon (Si) and Iron (Fe) values generated a higher number of defects. Increased yield strength (YS) and decreased elongation (E) also generated a higher number of defects. Based on the results, a defect prediction tool was created, where after entering the parameters of the material, it is possible to predict production hazards.

“…These work parameters must be known regardless of the finite element program used so that the simulation of the deep drawing process is the same as the experiments. Modern material resistance calculations, even when applied to classical problems of elasticity or plasticity theory, can not be conceived without the use of numerical calculation methods [19,20]. Therefore, this situation is a direct consequence of advances in the field of computers, both in hardware and software.…”

Deep drawing is a complex process influenced by the geometric parameters of the die-punch system. In the present paper we study the behavior of the semi-finished product, in the process of drawing deep cylindrical parts, using the finite element method and the software package of the ANSYS program. In order to reduce the cost and design time, an analysis of the variation of the radius connection is carried out, resulting in low energy consumption, using the finite element method. By analysing the radius of connection of the plate, we identify future directions useful in substantiating the elaboration of a judicious experimental program and optimizing the geometric shape of the finished parts.
