The K Factor
can you guys give me how you get your K factor? I have been reading about it a lot and it seems that to start the K factor would be t/T t=half of the metal thickness and T= Metal Thickness.

So would the K factor for .135 (10 gauge) be .500 ? did I figure that right?

the engineers at my company told me they figured the K factor by punching in numbers until they came close to a 80% bend allowance and not by reverse engineering for the K factor which left me scratching my head and refiguring all the cut sizes for the 10 gauge parts before I break because their drawings are wrong. for the 10 gauge they came up with a 54% K factor. now I am not sure how the % works in AutoCad would they be using .540 K factor? or does it not work like that?

any help with this would be great

The "K" factor is not even close to what you have there. That could be the reason fo his studdering. LoL

The "AK" factor is acually used in Grille sizing and stands for "Area Corrected" (I still have no clue what the K is for but whatever)
the formula for the "AK" factor is:

AK Factor -----> ------- x Velocity

**If I remember right, there might be some brackets around the LxW over 144? but either way... Thats the AK factor.
