Miter Folds

Has anyone figured out how to do a miter fold yet? If you don't know what
that is, picture this:
Take a strip of material say 4"x48"x1/2", chamfer the 2 short ends @ 45 deg,
cut 3 45deg v-grooves at equal spacing & leave .030" material at the bottom
of the groove. Now fold the machined part into a rectangle. Maybe one of you
sheet metal gurus can help me here.
Thanx, Dave

I would think it could be modeled without to much hair pulling, but I doubt you will be
able to unfold it.

I need to show it as one part (with the original part size) in the BOM &
unfold it for machining. Right now I'm faking it by making a drived part
from a dummy unfolded assy & hiding the separate parts in the Parts List.
This won't be a good idea though as soon as we start pulling data directly
from assemblies. Any ideas?

Create flanges using the offset option. make the offset longer then the
flange width. This will leave large gaps between your flanges. Use the
corner tool to close the flanges. This will give you a mitered corner.
I have placed an example in Customer Files.

I could easily be wrong, but I don't think that is what he is after. The
words 45deg v-groves and Machined parts makes me think he wants a weakening
grove to make the fold with.

No to Dave, Sorry. I'm interested in what he is trying to do. I tried
creating the part from the description he gave but if I got it right, I
can't see the reason for building a part that way. No that there isn't one.

The part is in CF called Miter Fold. (I just made an example shape, not a
sheet metal part) This is a common manufacturing process in the furniture /
woodworking industry where we are working with a piece of wood covered with
a colored paper. We cut thru the wood & leave the paper, then fold the whole
thing together. This makes for a cleaner seam & less assemby time.
Thanks for having a look.

I did one of those by ... cheating? ... making a face that would bend then
add the rest in an assembly because it needed to be shown both flat and
folded.

I tried starting a sketch on the back and projecting the bottom of the V then setting the
SM thickness to .03, and doing a fold. It just flipped the whole part 90º and made a
weird looking bump on the backside 8^)) I wonder if you possibly made the bottom of
the V groove flat a small amount, and placed a fold in the middle of the flat?

BTW In the future could you please zip files before posting. It makes them smaller and
also non zipped files often lock up Outlook Express. Thanks.

Oops! I just discovered the non-zipped file issue. The file has been
re-posted as Miter Fold 2.

Dave take a look in CF under your last post.
Is this what you're after?

Not exactly what you want, but see if the file I posted back would work. The web
thickness in that file isn't what you want, ... I meant to change it to .03 after I did a
couple of things, but forgot. It is real touchy and will never be perfect but...
depending on what you need it might work??

Good show Kent. I like that. It worked, that's the important part. Actually,
I would think that's the way it would have to be cut anyway.
