Bending Calculations
Bend Allowance (BA)
BA = (π / 180) * θ * (R + K * T)
Outside Setback (OSB)
OSB = (R + T) * tan(θ / 2)
Bend Deduction (BD)
BD = 2 * OSB - BA
K-factor is the ratio of neutral axis position to material thickness (K = t / T).
For the current bend, the neutral line radius is 2.50 mm.
