Press Brake & Bending
Radius Air Bending Calculator
Calculate the inside radius achieved in air bending based on V-die opening. Helps select the right die for desired bend radius.
- Inside Radius: Radius achieved with given V-die.
- IR/Thickness Ratio: Important for bend quality.
- Rule: IR ≈ V ÷ 6 for air bending.

Theory & Formulas
Air Bending Radius:
IR ≈ V ÷ 6
This is an approximation. Actual radius depends on:
- Material type and hardness
- Grain direction
- Punch nose radius
Note: For sharp bends, use bottom bending or coining.
