Bend Allowance Calculator
The HARSLE Bend Allowance Calculator is a specialized tool designed to help you calculate the precise bend allowance for your metalworking projects. Whether you're bending steel, aluminum, or other materials, this calculator ensures accurate results for determining how much extra length is needed to compensate for the bend radius and angle. Bend Allowance (BA) represents the length of the arc along the neutral axis of the material during a bend. The formula is:
BA = π × (R + K × T) × θ / 180
L = A + B + BA
where:
- R = Bend Radius
- T = Thickness
- K = K-Factor
- θ = Bend Angle
- A = Length A
- B = Length B
