HOW TO CREATE A FLAT PATTERN FOR A FLANGED DISK?

[cjacuinde]

Hi all,

I have created a round end cap with a flange for a tank. (Please see attached picture) We have a flanging machine that rolls the edges on round flat pieces of sheet metal. The issue is that no matter how I create this rolled flange in the model, I cannot get a flat pattern out of this. We need to know the size of the blank before rolling the lip on it and I have tried using the contour flange and it doesnt work, I have tried revolving in sheet metal and it still will not create a round flat pattern. It seems that no matter what I do, it will not produce a round flat pattern. Is this something that can be done in inventor or am I just trying to do something that inventor is not yet capable of doing? Help please?!

Hi!

This case  is a plastic deformation, not a bend (press brake or Die Forming).

Inventor will not flat this kind of geometry correctly.
