16. Specification and Characteristics of Drawn Parts

The specification should show the form of the part, state the material, specify dimensions and condition of symmetry.

D1 or D2 (not both)
D3
R1
R2
T
L1
L2
R3

D1 = Inside diameter at a plane of intersection
D2 = Outside diameter at a plane of intersection
D3 = Flange diameter at a plane of intersection
H = Depth of draw
L = Linear dimension
R1 = Punch radius
R2 = Die radius
R3 = Corner radius
S = 'Earing' due to directional property of material
T = material thickness
