Question
A brass blank was produced
using a force of 25.194
tonnes. The blanking punch
radius was measured as
87.889 mm. The blank was
prepared to be deep drawn
with a 98 mm diameter
punch. If you know that the
drawing ratio = 1.7959, the
deep drawing die radius = 10
mm and the yield strength of
:brass = 135 MPa, determine
a) The blank thickness =
mm
b) Shear strength of brass =
MPa
c) Tensile strength of brass =
MPa
d) Deep drawing die
dimensions =
mm
e) Show whether the
drawing process can be done
in one pass or not using
three feasibility tests
