Bending Corners - Sheet metal

Bending Corners - Sheet metal

Bending Corners - Sheet metal

(OP)
We make a lot of sheet metal guards and covers here and we bend a lot of intermitent folds (i.e. a 12" long sheet metal part with a 6" long flange in the middle bent 90-degrees) BUT we do NOT cut relief to make the bends.  They manage to bend the part so the stepped flange is flush with the outter edge of the part withOUT a relief cut.  This tends to stretch the material transition point of the bend where the relief would normally be (and doesn't leave a sharp edge like a relief cut would).  The problem is how to properly represent this with the sheet metal flange options in Inventor.

Any hints????

On the flange options go to the Relief Tab and choose None from the Relief Options.  That is about as close as you'll get.  IV does not have the ability to "stretch" the metal to simulate what you are doing.

That's what we've been doing but that shows an extremely sharp edge where it does the "false" relief and that (hopefully) is not how they end up making the part.  

Thanks.
