sheet metal bend radius change

stoked_kiwi_ — Wed, 04 Dec 2024 05:46:09 GMT

Hi im bending 5mm flat bar mild steel into a 300mm id square shape.

it came 304mm instead .

how can I change this to match my bending tool to get 300mm ?

many thanks David

Hi,

Please attach your file and we can have a look.

How did you model this? Did you use the Sheet Metal rules or Solid Rules and convert to Sheet Metal?

Cheers

Andrew

Your model measures 300 x 300 mm inside already. The Animated GIF will show this.

This would point towards the bend on the physical part being bigger than the modeled part. You could override the bend in the flange that created the bend and make bigger. Maybe measure the radius on the part you've bent and match in the model.

Hi thanks

yes 300 ID is what I am after

however when I put it in my brake press it comes out 304mm

I believe this is because my tool makes a wider radius

So im trying to find out how to adjust that on f360 so I get matching results.

Many thanks Dave

I can't open your part at the moment because I haven't updated Fusion but if it's the model that's wrong is it because you modeled the flange to the outside when it should have been inside? You can change this with the orientation option.

From the Modify menu you can select Sheet Metal Rules then modify the rule in the document. This will be saved so you can reuse in the future.

hi thanks . I had a look at that . if I change that

to orientation to the outside edge it would in theory fold everything so the OD would be 300 not the 300 ID .

I would still be 4mm out from what I draw to what comes out of the folder .

thanks

The standard setting for the bend radius is the material thickness, so you could enter something like 3.0mm instead and try again. Also name the rule.

You're going to have to guess a bit about what rad you need, measuring the bend radius on a part you've bent might be a good start point.

Also if you hold down the Ctrl key you can select multiple edges so you can measure the total edge length, you probably need it to reduce by a couple of mm.
