sheet metal forming
(OP)
hi all!
Can anyone tell me what the smallest diameter that can be achieved by rolling a 1/16" thick metal sheet?
Thank You!

RE: sheet metal forming
On stress bearing components in mild steel I use the following; bend radius = 2 x the material thickness, however I have used 1 x the material thickness for a 180 degree, none structural component.
But you must satisfy yourself that this will work for your problem.
The question has to be asked, why not use small dia tube and cut it to length? this is probably better from a stress and accuracy point of view.

Percent Extreme fiber Elongation in defined as:
50t[1-Rf/Ro]/Rf for single curvature [i.e., cylinders] &
75t[1-Rf/Ro]/Rf for double curvature [i.e., heads]
t = Plate thickness
Rf = final centerline radius
R0 = original centerline radius [infinite for flat plate]
You probably would want to dye check for cracks, too.

1) quarter hard temper, and bending axis MUST be perpendicular to the grain direction and (bending radius >= stock thickness) , for this material to be bent parallel to the grain size, it's advisable to maintain at 90 degree right angle the most.
2) Skin rolled temper, basically a grade which is suitable for fairly deep drawing operations where surface disturbances such as stretcher strains are objectionable. It cane be bent in direction.
3) dead soft temper, a very soft and ductile cold rolled strip, it is suitable for bending flat upon itself in any direction.
