When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table.
This video explains the process of importing an excel file saved as txt into autodesk inventor for bend allowance bend deduction calculation.
Inventor forum sheet metal k factor.
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.

Values for angles not defined within the table are calculated using a backup kfactor.

Access the style and standard editor to make edits to an unfolding rule or to set a new active standard rule.
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 have a k factor of t t 0 5 1 0 5.
Each row in a bend table specifies a bend angle.
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.

You can generate flat patterns by unfolding sheet metal features using a uniformly applied.
A bend table is a table of bend deductions arranged in rows and columns.
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.
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.
By default inventor uses a k factor for calculating bend allowances.
