Hi,
Can anyone assist me on how to unfold this pat? :-)

Hello,
It's a stamped part, like a pie tin (which also has a rolled edge).
If you wish, you can build a forming tool in the shape shown above and then "stamp" this out of a square blank.
Cut to round afterwards.
No time at the moment to put my model where my mouth is, but look into it and post back with your progress.

EDIT: I don't believe this method will generate accurate blank parameters and such, as it is more stamping/drawing than forming.
SW does better with forming.
But I believe the above will generate something to start by.
I will laser cut this part and stamp it afterwards.
I'm not certain on how the 'unfolded' version would look like..
I think this can be achieved in a Premium version of SolidWorks with the surface flatten feature, but I'm currently on a Professional.
Surface flatten could generate a dxf for the part, but not sure how accurate it would be.
Use Flaten surface to make your first tryout
I've played around with this type of stamping in the past for some prototype parts we wanted to try but did not have enough confidence in the tools at the time to commit to the cost of having a stamping shop make custom tooling for the part. I would be interested to see if anyone has any more wisdom to share on the best way to design parts for stamping that would be much appreciated.
I don't know the exact term but I've got one part in particular that I think I could reduce production costs on significantly if I could design it to be stamped from one piece but it would require multiple bends stamped in one operation similar to some of the operations in this video:
could you upload your file? sometimes you could make soft tooling to make your part able
I'll set a reminder on my phone as it's on my home computer.
Joel Gilbert - Thanks for posting that video link. I've never seen that type of tooling before. It is amazing the type of tooling you can create with that technique.

In order to flatten this (in sheet metal) you will have to remodel it using the sheet metal tools and machine off the top taper since it looks like you are not wanting to keep the tabs (you used a delete face on them to get rid of them?). The part in green is a circular base flange (12mm in dia.) with an edge flange bent up 45° then cut (normal) in order to achieve the height.
This shows the original part and the new sheet metal part on top of each other. Other than the top edge which will be machined (if you need it parallel to the base) and the bend radius which the sheet metal part will require.
Flat pattern using a .5 k-factor.
I would describe as conical pan rather than cylinder.
No bends?
No rips?
Top face is not perpendicular to the side face?
Not uniform thickness?
