MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
I'm trying to produce an aluminum frame section that requires the following corner section. I only want a dozen or so pieces so I don't want to go down the tooling for deep drawing press route. My usual local tin bashing company (basic metal folding/forming equipment - no CNC capabilities) cannot do them. The easiest way I figured was to make it in 2 parts then weld them together but this may become economically unviable.
I have access to laser/water jet cutting so can cut the un formed blanks - but its what I economically do with them from there.
This isnt a commercial venture - its for a personal project, the Solidworks package is my employers.
TIA

turn two flanges and cut them into quarters you will get two usable quarters at least
Put that together 4 times, make a circle and get it turned / milled then cut it into 4 quarters to give you what you have there. It would be far easier to make round then cut.
Does it have to be metal? 3D printing could also be your friend if strength isn't an issue.
Cast it and polish it? How accurate does it need to be?
Thanks for the replies!
I like the idea of making a full circular then dividing it - I've been stuck in the train of thought of just making a quadrant. Good thinking!
It does have to aluminium as it is welded to some simple press brake formed sections to make the complete rectangular shaped frame.
As suggestions above, turn as a one piece then get it wire eroded and you will get 4 usable quadrants.
