“…The material used in the simulation is a 0.8 mm and 1.0 mm thickness of SPCC sheet metal with a cylindrical flange cup-shaped morphology in the deep drawing process. Wrinkle phenomenon can be demonstrated by ANSYS and ABAQUS simulation automation as performed by [11,14,18,19]. A simple simulation using Solidworks 2017 version can also demonstrate the phenomenon of wrinkles as in this study are shown in Figure 5.…”

A Sheet Metal Forming (SMF) process, especially deep drawing, is one of the manufacturing processes that commonly used in the automotive industry. Compared with casting and forging, the SMF process has several advantages, including lesser weight materials and broader variations in shape that can be made. One of the problems in the SMF process is the wrinkling phenomenon, which can cause the size and appearance defects of sheet products. The wrinkle occurs because of the mechanical properties of the material, product geometry, and blank holder force (BHF). Several variations of BHF were applied in these simulations and experiments to eliminate the wrinkle defects of cylinder flange cup test products. The characteristic of the cylinder flange cup is from the cold-rolled coiled steel plate (SPCC) type of material with a thickness of 0.8 and 1.0 mm, the height of 10 mm, the inner diameter of 58 mm, and flange diameter of 76 mm. Simple simulations of the SMF process were carried out by using Solidworks with version 2017, and the experiment was carried out at a 600 kN press with a punch velocity of 40 strokes per minute and blank holder force variations from 0 to 21 kN. The experimental data performed with a single die on a flanged cup cylindrical test material shows that the higher the blank holder force (BHF) number, the smaller the wrinkle defect, and it can be eliminated starting from the BHF number of 15 kN.

In aeronautic sectors, lightweight materials are very demanded in order to reduce fuel consumption. Therefore, thinning drawn cups are very recommended. Reduction of thickness led to many geometrical and physical failures that damage the final product. Since most lightweight materials had a high level of anisotropic, the presence of earrings is one of the most significant failures faced in the deep drawing process. Many functions were developed in order to control these undesirable earrings in sheet metal parts. In this paper, a simulation of a 3D cylindrical deep drawing model for AA1050 and AA1100 aluminum alloys using ABAQUS finite element software was achieved. Prediction of earing phenomenon in deep drawing process was carried out. Moreover, the impact of punch corner radius and die shoulder radius on flange earrings was analyzed and a reduction of the percentage of earring heights was investigated.

“…In this study, we assume that the coefficient of friction between the punch and the blank is m p = 0:25, that between the blank holder and the blank is m h = 0:125 À 0:2, and that between the die and blank is m d = 0:125 À 0:2. 20 With deep drawing, tearing defects are caused by uncontrolled deep forces (equation (15)) that cannot be transmitted to the bottom of the cup 20…”

In this article, a deep-drawing process using a double-action hydraulic press is examined for its ability to machine the shaping deformation of a fuel-filter cup made from SPCC steel. Many researchers have studied the geometric, physical, and technological parameters of the deep-drawing process. However, most of those studies ignored the optimization parameters of the two shaping deformation states to ensure uniformity of thickness and the disappearance of wrinkling and tearing during machining. In this study, geometric and technological parameters (e.g. blank-holder force, die-shoulder radius, and radial clearance between punch and die) are optimized in both states. The deep-drawing process for a fuel-filter cup is simulated using ABAQUS software, and optimal parameters are determined by applying the Taguchi orthogonal array computation and combining it with an analysis of variance method. The numerical results are then verified with corresponding experiments. The obtained numerical and experimental results show that the die-shoulder radius is one of the most influential parameters affecting the shaping of the cup during the deep-drawing process. Moreover, the influences of technological parameters on the formability of sheet metal are finally analyzed and selected for designing and improving deep-drawing molds.
