“…Based on the measurements of the required final product (diameter, thickness, and height), a template is designed to draw the aluminum sheet with the required measurements through well-known design equations for the deep drawing process [27]. These equations determine the diameter of the initial work-piece, the diameter of the template, and the diameter of the piston.…”

The deep drawing forming process, classified under sheet metal working, is a promising and essential metal forming process that has attracted much interest due to its wide application in micro-production. The process parameters, such as the cross-head speed of the machine, have a significant influence on the quality of the product. The impact of two essential parameters was investigated to minimize or eliminate the product's production defects, such as thinning, tearing, and scratching. The first one was the impact of using two types of lubricating oil (grease and wax), and the products were compared with the dry condition (without using a lubricating oil). The second is the impact of changing the cross-head speed of the machine from 5 to 15 mm/min. This work aims to determine the optimum operating condition that prevents any defect in the product. The results showed that using lubricating oil resulted in better product shape, and the wax is better than grease in eliminating product defects. In addition, the results showed that the lower machine speed is preferred for eliminating production defects, where the final product has no obvious thinning, tearing, or scratching. The final product shape was evaluated visually because eye observation is the only way to judge the product shape.

“…Sheet metals that have undergone remanufacturing and multiple rolling will present fibrous tissue or preferential orientation caused by crystallization, which will lead to anisotropy, meaning the material exhibits different mechanical properties in different directions. This anisotropic behavior has obvious influences on deformation during the forming process, such as earring and fracture on straight walls in deep drawing [1][2][3]. In general, the anisotropy of machined sheet metal and the resulting stresses and loose areas have a significant effect on its performance during forming and use, as in the following examples.…”

Since sheet metal exhibits significant anisotropy in processing and forming, which has a significant impact on its performance during processing, forming, and use, we explore the anisotropic behavior of materials in the forming process of sheet metal. The ability of the Yld2000-2d criterion to describe anisotropic behavior is analyzed, and its accuracy for characterization of the anisotropic behavior of metal plates is improved, based on which anisotropic behavior is predicted in three-dimensional space. Theoretical and experimental results on the anisotropy of sheet metal are compared, and two materials, 5754O aluminum alloy and DP980 steel plate, are tested and analyzed, and the anisotropic behaviors, such as three-point bending and cylindrical deep-drawing, are well predicted.
