k factor for sheets and bending radius

[Edis]

Good morning to all,

I'm trying to make my designs with pious development. for that I should parametrate the k factor and the bending radius regarding the plate function. I made myself give from our supplier the bending radius of the knife regarding the folds that is a 0.8. Some of you manage to direct me to calculate factor k, how can I get it. some advice on this for such parameters. then regarding the fold line once set these two parameters the program calculates it automatically?

Thank you very much

He talked about it and scrambled in the forum.
factor k depends on many variables and is obtained for practical tests.
you cut a piece of sheet defined, fold and measure the result. for deduction is obtained withdrawal or extension of the material.
if you want in the resource section there is an empirical calculation

set these two parameters the program calculates it automatically?

Of course.

Of course.

Thank you very much.

where I worked before I had tested the different materials (aluminum, iron and stainless) of various thicknesses (from 1.5 to 6 mm) to determine the various "k" with the various blades. a job but surely where there were few margins of errors.

there is no other way to detect factor k.
already use a different measuring quarry can change the result a lot.
it could also lead to relief that the result can change from one batch of sheet to another or from the parallel fold or perpendicular to the direction of lamination, but are aspects to be taken into account when making artifacts that require accuracy greater than the tenth of millimeter.

I agree with everything. it was a job but in the end we got a good result. “ Fortunately” we didn’t need the tenth of a millimeter and however we had a fold on which to “load” all errors.
