Hi all,
Can anyone explain the logic behind this bend?
It seems strange if the flatten state of the part should be shorter? - it is certainly not what happens in real life.
Bend:
Unbend:
Please see attached part file and pdf drawing.
Seems correct to me. Do some research on what a k-factor is since that will explain it better than I can. Typically, each bend will stretch the metal just a bit so this has to be compensated for when estimating what the flat pattern of a formed part will look like.
