Sheet Metal Relief
Sheet Metal Relief
(OP)
Hello All,
This might be a basic question but asking for a better understanding.
Whenever I have a chance to design a sheet metal part, I always use an outside bend for flanges to avoid reliefs. I don't know the reason but I hate adding relief to my design. Is anyone out there, who doesn't like relief like me?
Could anyone please explain the really important factor of relief? and why we should consider it in designs?
Thank You!

It doesn't matter if you dimension to the inside or outside, the material goes through a deformation when being bent and therefore the flat pattern must be cut to allow for this. You need to understand what the neutral axis is to understand bend relief.

I am not the expert in welding the different reliefs, but, I know that is basically one of the reason for the reliefs, from my experience. If you're never going to weld the corners, then, you don't worry about reliefs.
