Bending Factor In Sheet Metal

In sheet metal design the k factor is used to calculate how much sheet metal one needs to leave for the bend in order to achieve particular final dimensions especially for between the straight sides next the bend.

Bending factor in sheet metal.

May 18 2016 at 11 04 pm. In sheet metal the k factor is the ratio of the neutral axis to the 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. The line where the transition from compression to stretching occurs is called the neutral axis.

Just that the leaf brake can serve a shop well where sheet metal bending isn t an everyday job. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. Calculate k factor bend allowance and y factor for sheet metal bending. Therefore using k factor there is no need to calculate sheet metal flat length manually.

K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1. Bend allowance and k factor.

K factor plays a key role in understanding the limits a material can handle during sheet metal bending. The part of the material that bends. Sheet metal flat length can be calculated using cad softwares. Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.
