How to Use This Calculator

  1. Enter the thickness of your material
  2. Select the material type or enter custom shear strength
  3. Input the total cutting perimeter length
  4. Adjust the safety factor based on your operation complexity
  5. Click Calculate to get the required press force

Calculation Formula

Press Force (tons) = (Perimeter × Thickness × Shear Strength × Safety Factor) / Conversion Factor

Conversion Factors: 1000 for mm/MPa, 2000 for in/psi
