How to flange a circular face

[Anonymous]

Hi,  I am trying to add a flange like the one show to outside curved edge of this sheet metal part. I have tried a contour role but it errors when I attempt to flatten it.  Any help would be greatly appreciated

1. Create a polygon.

2. Create a face.

3. Create your flanges.

Hi ken.perf,

How is this to be manufactured?

Often a round flange for a part as you show is a compound curve, in which case Inventor will not create that type of flat pattern.

Other times we'd create the curved flange as a 2nd part and weld it on the first.

The example Roelof.Feijen shows is a 3rd option I suppose, but I would suggest you run this by the folks in the shop before doing it in that manner.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

This flange will be put in with a seam machine. The curve is actually set up as a series of arcs to avoid using a 2d equation curve. I was afraid this would not be supported in Inventor 2013, does Inventor 2017 contain this functionality?

Nope..

Not very practical for a manufacturing... I would just weld a piece of flat strip to the edge of the main body.

Cheers,

Hi! Contour Flange was designed to tackle elbow joint design from a long piece. Your design requires so-called Sweep Flange, which is not unfoldable. You can create flange like profile at one end and simply sweep it along the circular edges. But, still the sheet metal part cannot be unfolded.

Thanks!
