Press Brake & Bending
Spring Back Calculator
Calculate spring back angle for sheet metal bending. Helps determine the overbend angle needed to achieve the desired final angle.
- Spring Back Angle: How much the bend opens after release.
- Required Bend Angle: Angle to bend to compensate.
- Material Properties: Yield strength and elastic modulus affect spring back.

Theory & Formulas
Spring Back Overview:
Spring back occurs because the material's elastic deformation recovers after bending.
Factors affecting spring back:
- Material yield strength (higher = more spring back)
- Material thickness (thinner = more spring back)
- Bend radius (larger = more spring back)
- Bend angle
To compensate:
Overbend by the spring back angle.
