factor k from the book of pruners

[MARCOC]

Hi.
I read on the book of pruners,

taking part of the original text "how to calculate the factor k" this parameter establishes the position where the tolerance of the fold is calculated. to calculate the bending tolerance the following equation is used. . .
2*pi*(folding + linear offset*thickness\2)*(fold angle\360)

you know what it means by linear offset

If you're looking for the inventor's guide, I think it's all very well explained.

I read, but there's also a couple of unclear things.

from wiki
fold compensation
ltot.

v= is the result of the calculation of the tolerance of the fold.

It's okay.

Then he tells me...

in inventor, the tolerance of the folds is calculated by the following equations

lba=2(p+q)*tan(b/2)+v

Now I do not understand but if in lba always appears v as the calculation I am v
to me not clear... you can clarify me
