Tags: K factor calculation
Hi everyone,
I am testing the k factor calculation listed on this web site and I have questions, here goes:
Tooling:
Wila new standard
Punch: BIU-021 (1 mm radius)
Die: OZU-053 (16mm x 30 degrees)
Material: crs
Material thickness: 0.101″
When I did the testing, I performed the formula (bend allowance and K factor) and compared to a actual bend deduction and there was 0.015″ difference. The calculation was larger by 0.015″ compared to the actual measured deduction.
How can I correct the calculations to be more precise?
We have K-factor calculator, which can help you.

Maybe try to aproximate the length with the BD (bend deduction) if u use thypical value of thickness and angle measure the initial length of the blank and compare with the final length these amount discount of the next bending
