Table I: B. Material Properties Carbon steel plate material SAE-AISI 1008 for sheet metal blank stamping is used. The mechanical properties are summarized in Table 1, where oy, is the yield stress, 6, is the ultimate tensile strength and K the strength coefficient. From an analysis of the forces in equilibrium during the formation of a deep-drawn cup, the use of an approximate equation for the total punch force as a function of the diameter of the blank at any stage in the process. An approximate equation of the maximum drawing force F (in N) or punch load has been developed F=2D,to, (D,/D, - C) Details of Various Parameters of Models Fig. 5 Different meshing of die assembly Fig. 4 Schematics diagram Deep drawing process & various parameters of deep drawing (Not to scale Jrawing is a sheet metal forming operation used to make cup shaped, box shaped, or other parts. Fig. 4 represents the basic lrawing operation with the main dimensions and parameters. Fig. 8: Equivalent Plastic strain contour model 2 £) Comparison of the Vejormed shapes Considering the results at different time instants and considering all die assembly, it is observed that the model 1 represents the total depth circular cup drawing with wrinkle defect. With model 2 only 20.285mm in depth is obtained with negligible defect. 3D Axisymmetric Model 3 permits to calculate the cup depth of 17.762 mm, however the deformed thickness sheet metal decrease significantly.
