The minimum sheet metal bending height should be calculated as 2 times the thickness of the sheet metal plus the bending radius, i.e., H ≥ 2t + R. As illustrated in the accompanying figure, if the bending height is too low, the .The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by Protocase. We go beyond the general rules of sheet metal bending, as our customers want tight bend radii for sheet metal parts. It is possible to choose other bends if you require, but additional lead time and tooling charges may apply.
Recommended inside bend radius for sheet metal parts should be equal to material thickness. For hard materials (Stainless steel, CRCA), an inside bend radius equal to 0.65 times of sheet thickness is also enough.

Working with an included bend angle of 60 degrees, a material thickness of 0.062 in., an inside bend radius of 0.062 in., and a bend allowance (BA) of 0.187 in., you get a negative bend deduction. That means you subtract the negative BD (again, the same as adding) when doing the flat-blank calculation.
Your bend radius with two bends is something like half of your length measurement. Can they calculate the metal deformation across the bend with that kind of accuracy? . I'm used to +/-.030" as the standard tolerance for bent sheet metal parts without really thinking about it. Tighter can be achieved, so +/-.015" seems reasonable if that's . Bend Radius. Fabricators can only bend sheet metal so far before damaging it, and we call that smallest possible inner curvature the bend radius (or internal radius.) You can slash your lead time and avoid the high cost of custom tooling by designing your part’s bend radius to 0.030"—the industry standard for sheet metal up to 0.125" (⅛ .
