Assuming that in drawing of cups, the thickness of the cup bottom and wall is the same as that of the original sheet, ?nd an expression for the ratio of the cup height to diameter, h/d1, in terms of the ratio of blank diameter to cup diameter, do/d1.
Evaluate h/d1 for do/d1 = 1.5, 1.75, 2.0, and 2.25 and plot h/d1 versus do/d1.
