K Factor in sheet metal bending is a constant used to calculate sheet metal flat length or Flat-pattern. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. During sheet metal part bending, the inside bending surface is compressed, whereas the outer surface is K-Factor SheetMetal.Me - Sheet Metal Fabrication calculate k factor bend allowance and y factor for sheetSince the K-Factor is based on the property of the metal and its thickness there is no simple way to calculate it ahead of the first bend. Typically the K-Factor is going to be between 0 and .5. In order to find the K-Factor you will need to bend a sample piece and deduce the Bend Allowance. The Bend Allowance is then plugged into the above equation to find the K-Factor. 1. Begin by preparing sample blanks which are of equal aSee more on sheetmetal.meInventor Sheet Metal k-Factor: Sample Bend Tables calculate k factor bend allowance and y factor for sheetSep 03, 2015 · By default, Inventor uses a K-Factor for calculating bend allowances. 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.
