Sheet Metal Corner Treatments
Sheet Metal Corner Treatments
(OP)
Using NX 9 Sheet Metal Application. The Closed Corner Tool list 6 different Corner Treatments.
Open/Closed/Circular Cutout/U Cutout/V Cutout/Rectangular Cutout. When would you use a particular Cutout and Why…?
Some corners look almost the same….
Haven’t been able to find any information.
Thank You

RE: Sheet Metal Corner Treatments
If you're not planning on welding the corner, you may want it as-closed as possible despite any minor tearing or stress on tooling.
If you're fully welding the unit, you may wish to minimize gap but still leave a minor amount.
If you don't care about the opening at all, and can leave as big of a gap as is practical... well you have several choices.
It's mostly design choices based upon manufacturing efficiency, material stress considerations, and forming tool wear/stress.
Maybe some other reasons that slip my mind.

Putting a corner cut that requires a tool he has to buy, especially for a short run job, will not win you any friends.

You are judged not by what you know, but by what you can do.
RE: Sheet Metal Corner Treatments
If your sheet metal part is mounted in an aircraft or on a moving vehicle, the punched out corners are stress raisers, and you need to worry about fatigue. You need to relieve the corners somehow. If you are designing a static box, you may want to close the corners down as much as possible. I interpret your table as a set of punched corner options. What do you need to accomplish?

Sometimes stress concentration as drawoh mentions, sometimes manufacturability, sometimes aesthetics...
