“…The blank holder force magnitude will be changed in a fluctuating around 1000 N. The distribution of blank holder force in every punch stroke on the semi-active blank holder force control could be used as a reference for the process of deep drawing. The semi-active blank holder control system would be increases the material formability more than 30 %, thus it can be employed to improve Lin's and Gavas's study (experiment) [3] [7], and can be considered feasible to prevent wrinkling and cracking.…”

This paper presents simulation of drawing force and thickness deformation in deep drawing which employs semi-active blank holder force system, to solve the problem of cracking and wrinkling. The method of slab with feed back control failure criteria, was employed to make the modeling system and the semi-active blank holder to prevent wrinkling and cracking in forming low carbon steel sheet, without lubrication (μ=0.4). In this study, the mechanical properties of the material were chosen since that they equivalent to those of low carbon steel with its thickness of 0.2 mm, k = 572 N/mm2, UTS = 391 N/mm2, yield stress = 309 N/mm2 and n = 0.2. The diameter and the depth of the cylindrical cup-shaped product were 40 mm and 10 mm, respectively. Results from simulation have shown that the semi-active blank holder system can control very responsive against changing of deformation condition. The optimum of initial blank holder force is approximately 3000 N up to 4000 N. In the early stages (initial stroke), blank holder force system could be responsive to prevent cracking, and at the end of the punch stroke, it is very effective to prevent wrinkling. Simulation of semi-active blank holder force control system is excellent in model formation to prevent cracking and wrinkling.

“…But, as shown in Ref. 8, it can be said that during drawing, the ABS method slightly prevents wrinkling and eases metal flow. Consequently, thinning in the arc portion of the cups is slightly fewer less than in the conventional method.…”

“…This system is similar to ABS used on automobiles hydraulically and mechanically. Therefore, the system was called ''Deep drawing with ABS'' by the author [8]. In their study different blank geometry, punch velocity, blank material and die dimensions have been used to produce square cup when compared to this study.…”

This paper deals with increasing the drawing height of metal conical square cups with anti-lock braking system (ABS). A novel technique enabling higher drawing height than that achieved in the conventional deep drawing process is introduced, and the principle of the process is explained in this paper. Results of experiments conducted using aluminum alloyed Al-1050 blanks of thickness of 1 mm to draw conical square cups are reported here. Measured drawing load, drawing height and thickness distributions were compared with those obtained from the conventional method. The experimental results showed that higher drawing height of the cup can be achieved by the use of ABS.

“…In the present work, we investigate the effect of PBHF parameters in deep drawing of rectangular aluminum cup through experiments and FEM simulation. According to results of previous studies, using PBHF is an effective method to improve drawability of sheet metal while eliminating failure [7,8,15]. Despite this fact, additional process parameters of PBHF make application and control of this method more complicated than using constant BHF.…”
