Calculate Punch Force Requirements
About Punch Force Calculator
This calculator determines punch force requirements for metalworking operations, including tonnage needed for punching holes in various materials.
Punch Force Formula:
Force = π × Diameter × Thickness × Shear Strength
Material Shear Strengths (PSI):
- Mild Steel: 45,000 PSI
- Stainless Steel: 60,000 PSI
- Aluminum: 25,000 PSI
- Copper: 30,000 PSI
- Brass: 35,000 PSI
- Titanium: 80,000 PSI
