                                                                                                  Material : Al

Sheet Thickness : 1.5 mm

All dim. in mm

Solution

Neglecting sheet thinning/thickening,

Area of flanged cup = Area of blank

The cup shape is divided into 3 primitives as under

Annular Disc

Area

A1 = ∏/ 4 (152  - 102 )

= 125 ∏ /4 mm2

Cylindrical Part

Area A2  = ? DL

= ? × 10 × 8 = 80 ? mm2

Circular Disc

Area A3 = ∏ / 4  D2

 = (∏ /4 )× 100 mm2

Area of flanged cup

A = A1 + A2  + A3

= 545 ∏ / 4

931_Calculate Size of Blank Required for Drawing 2.png

                                  = 545/4  ∏

Diameter of blank, Db  = √545

                                 = 23.35 mm

Diameter of blank can be chosen to be 25.00 mm to account for material properties, die clearances and trimming allowances.
