If I make a really sharp 90 degree bend in sheet metal, I can mark the location of that bend at the exact distance from the edge and just bend on that mark. The inside dimension will then be real close to that exact dimension. OK, probably just a tad short of it due to compression, but close. But there are two problems I can see with this: first it is never desirable to make a real sharp bend as there will be a lot of stress and also cracks may/will appear on the outside radius of that bend. And second, I can not mark two or three bends in a row using this procedure as there will be some compression or stretch in the metal and each successive bend will be off by a bit more than the last.
I know that there are formulae for determining the location of each successive bend, but is there a way of controlling the effective distance between the bends by controlling the inside radius of the bends? Is there a formula for that? I imagine it would be based on the thickness and perhaps on the type of metal.
