What does this calculator do?
Suggests a preliminary die V-opening, inside radius and minimum flange from material thickness and bend angle.
Which inputs are required?
- Material thickness
- Bend angle or method
Output: Recommended V-opening range, inside radius and flange reference
Formula or planning rule: Typical planning range: V = 6t to 12t; estimated inside radius = V / 6; minimum flange about 0.7V
How should the result be verified?
Check the selected tool's load rating, the press brake capacity and working length, the actual material data and the bend method. Use a controlled first piece and measure the released part before approving production.
