An Engineering Approach to Die Design
This calculator is provided as a design aid onlyThe results are based on traditional die engineering practices
Material Thickness 3Bend Angle (degrees) 90Bend Radius (inside) 6
HARD STEEL OR ROUND BARFormula: 0.01745 * angle * R + t/2
Allowance 10.923
Blank Length = A + B + Bend Allowance
SOFT STEEL: Wipe with Spring PadFormula: 0.01745 * angle * R + t/5
Allowance 10.023
Blank Length = C + D + Bend Allowance
SOFT STEEL: V-DieFormula: 0.01745 * angle * R + t/3
Allowance 10.422
Blank Length = E + F + Bend Allowance
SOFT STEEL: Wipe with Pad PressureFormula: 0.01745 * angle * R + t/4
Allowance 10.173
Blank Length = X + Y + Z + (2 x Bend Allowance)
