The Punch Force Calculator serves as a pivotal tool in metalworking, aiding in the determination of the force required for punching holes in sheet metal. It calculates the force needed based on essential parameters such as blank diameter, sheet metal thickness, and the material’s shear strength.
Formula of Punch Force Calculator
The formula employed by the Punch Force Calculator is:
Fp = π * Db * t * σb
Where:
- Fp: Punch force
- Db: Blank diameter
- t: Thickness of the sheet metal
- σb: Shear strength of the material
General Terms and Conversions
To assist users and provide added value, here is a table with commonly searched terms related to metal punching:
| Term | Description |
|---|---|
| Shear Strength | Material’s resistance to shear stress |
| Blank Diameter | Initial diameter of the hole before punching |
| Sheet Metal Thickness | Thickness of the metal sheet being punched |
| Punch Force | Force required for punching a hole in the sheet metal |

This table serves as a quick reference guide for those exploring these terms, aiding in understanding without the need for manual calculations each time.
Example of Punch Force Calculator
Let’s consider an example to illustrate the practical application of the Punch Force Calculator.
Scenario:
- Blank Diameter (Db): 10 mm
- Sheet Metal Thickness (t): 2 mm
- Shear Strength (σb): 400 MPa
Calculation: Using the formula Fp = π * Db * t * σb Substituting the values: Fp = π * 10 * 2 * 400 = 2513.27 N
