K-factor (aeronautics), the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter. K-factor (centrifugation), relative pelleting efficiency of a given centrifuge rotor.

What is a K factor in sheet metal?

K-Factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part. When you select K-Factor as the bend allowance, you can specify a K-Factor bend table.

What is the bend allowance formula?

The formula (See Bending Formulas) is: Bend Allowance = Angle * (π / 180) * (Radius + K-factor * Thickness).
