Punching Calculator
Using the data below, you will get the parameters of punching
Material (KN/mm2) – material shear strength
Thickness (mm) – thickness of material to punch
Punching force (Tons) – total necessary force to execute the punch
* calculations are for punching
Common material’s shear stretngth are as follows: unit: KN/mm2
| Aluminum | Brass | Low Carbon Steel | Stainless steel |
|---|---|---|---|
| 0.1724 | 0.2413 | 0.3447 | 0.5171 |
