The V-Series Black Calculator helps you determine optimal bending parameters based on sheet thickness. It calculates model, shoulder radius, minimum flange, angle, punch radius, and more—ensuring accurate setup for press brake operations.

📐 Key Formulas

Model = 0.391 × Thickness + 0.735

Shoulder Radius = 0.926 × Thickness − 0.078

Min Flange = 3.882 × Thickness − 0.111

Min Angle = 6.464 × Thickness + 28.399

Min Punch Radius = 0.370 × Thickness + 0.950

1. Sheet Thickness: Material thickness (mm or inch).
2. Model: Tooling model based on capacity and size.
3. Shoulder Radius: Tool shoulder curve for forming.
4. Min Flange: Minimum flange length for a clean bend.
5. Min Angle: Smallest achievable bending angle.
6. Min Punch Radius: Minimum tool radius to avoid cracks.
