Press Force Calculator
Calculate required press force for blanking and punching. Enter cut perimeter, material thickness, and shear strength.
Results
Blanking / Punching Force
- F — required force (N)
- L — cut perimeter (mm)
- t — material thickness (mm)
- τ — shear strength (MPa = N/mm²)
Shear Strength Reference
| Material | UTS (MPa) | Shear τ (MPa) |
|---|---|---|
| Mild Steel | 370–450 | 250–320 |
| Stainless 304 | 515–750 | 350–500 |
| Aluminium 6061 | 240–310 | 150–200 |
| Copper | 210–370 | 140–250 |
| Brass | 310–450 | 200–300 |
L = π × 50 = 157.08 mm
F = 157.08 × 2 × 300 = 94,248 N = 94.2 kN ≈ 9.6 tonnes
Professional instruments for industrial applications.
Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
