- Bend Allowance CalculatorNeutral-axis bend allowance (K-factor method)Bend allowance is the length of material that disappears into a bend. Bend a flat strip and the finished part is always shorter…
- Sheet Metal Flat Pattern CalculatorK-factor developed length methodA flat pattern is the blank you cut before anything is bent. It is never the sum of the finished dimensions, because each bend…
- Press Brake Tonnage CalculatorAir-bend three-point force formulaA press brake bends sheet by pressing it into a V-shaped die, and the force that takes depends far more on the die opening than…
Which one do you need?
- Bend Allowance Calculator
- Calculate sheet metal bend allowance from thickness, inside radius, bend angle and K-factor. Get bend deduction, setback and neutral axis radius.
- Sheet Metal Flat Pattern Calculator
- Calculate the flat blank length for a multi-bend sheet metal part from thickness, K-factor, bend angle and radius, using bend allowance or deduction.
- Press Brake Tonnage Calculator
- Calculate press brake tonnage for air bending: total tons, tons per foot, recommended V-die opening, achievable inside radius and minimum flange.
