K-Factor Calculator
Calculate bend allowance, bend deduction, and K-factor for sheet metal
Fabrication Standard: K-Factor is the ratio of the neutral axis location to the material thickness ($t$). Standard air bending typically uses a K-factor of 0.33 to 0.50 depending on material properties.
Sheet Metal Bend Parameters
Calculation Results
⚠️ Sheet metal bend calculations depend heavily on tooling V-die width, grain direction, and material tensile strength. Always perform test bends for precision parts.
