Autodesk Inventor Sheet Metal K Factor

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

Autodesk inventor sheet metal k factor.

By default inventor uses a k factor for calculating bend allowances. Inventor forum sheet metal k factor. Michael davis owner of ycg inc. 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.

A bend table is a table of bend deductions arranged in rows and columns. 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.

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. When unfolding if a bend radius or angle does not correspond to a specific entry a process interpolates between adjacent values in the table. You can generate flat patterns by unfolding sheet metal features using a uniformly applied. Each column specifies a bend radius.

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. 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. Each row in a bend table specifies a bend angle. Sheet metal k factor.
