Calculation Formula

Die Opening (D) = 1.27 × Thickness (t) + √(Punch Force (F) / Tensile Strength (σ))

Where:
D = Die Opening (mm)
t = Material Thickness (mm)
F = Punch Force (kN)
σ = Tensile Strength (MPa)

Working Principle

This calculator uses the following formula to determine the optimal die opening size:

Die Opening (D) = 1.27 × Thickness (t) + √(Punch Force (F) / Tensile Strength (σ))

This formula accounts for both the material thickness and the force required to punch the material, adjusted by the material's tensile strength. The calculation ensures that the die opening is large enough to allow for proper material flow during blanking while minimizing punch force requirements.

Important Notes

  • The material properties used in this calculator are approximate values. For precise calculations, consult material specifications from the manufacturer.
  • This calculator is designed for simple blanking operations and may not be suitable for complex die-cutting applications.
  • The shear strength is calculated as a percentage of the tensile strength, which is a common approximation in manufacturing engineering.
