Sheet Metal K Factor Formula

For our example it comes to.

Sheet metal k factor formula.

4 1 893 2 214. Calculate k factor bend allowance and y factor for sheet metal bending. 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. You can use this k factor calculator to calculate k factor using reverse engineering method.

Best way to calculate k factor in sheet metal is by reverse engineering. As a result overall sheet length increases. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. The part of the material that bends.

In this article we will discuss sheetmetal bend deduction bend allowance k factor y factor and sheet metal flat pattern calculations. Plug the bend allowance ba the bend angle b inside radius ir and material thickness mt into the below equation to determine the k factor k. Cad tools use k factor to calculate sheet metal blank. K factor is a ratio of location of the neutral line to the material thickness as defined by t t where t location of the neutral line and t material thickness.

The k factor is the most important and elusive variable of bending because it varies both as a function of the material and according to parameters such as angle and tooling. Subtract twice the leg length from the initial length to determine the bend allowance. This change in sheet length depends on the position of neutral axis or k factor.
