Autodesk inventor sheet metal k factor.
K factor a constant determined by dividing the thickness of the sheet by the location of the neutral axis which is the part of sheet metal that does not change length.
Values for angles not defined within the table are calculated using a backup kfactor.
Using the bend table unfolding method sheet metal parts unfold using empirical values that are measured or derived and applied to specific bend angles within the table.

Sheet metal k factor.
So if the thickness of the sheet was a distance of t 1 mm and the location of the neutral axis was a distance of t 0 5 mm measured from the inside bend then you would.
Using a bend table.
I don t even know if you could enter a 0 0 for a k factor in inventor possibly something like 0 0000000000001 or it could be 1 0.

Inventor forum sheet metal k factor.
The default k factor is 0 44 which simply means that inventor is assuming that 44 through the cross section of the part the material is not stretched or squashed when bending and therefore this slice of the folded part will give the true length of the flat pattern.
