Bending Factor In Sheet Metal

K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length.

Bending factor in sheet metal.

Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line. Sheet metal flat length can be calculated using cad softwares. The part of the material that bends. May 18 2016 at 11 04 pm.

For example if the value of k factor for given material thickness and bending machines is known. 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. The line where the transition from compression to stretching occurs is called the neutral axis. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.

When metal is bent the top section is going to undergo compression and the bottom section will be stretched. In sheet metal the k factor is the ratio of the neutral axis to the material thickness. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. 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.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. K factor plays a key role in understanding the limits a material can handle during sheet metal bending. Bend allowance and k factor. Calculate k factor bend allowance and y factor for sheet metal bending.

Types of metal bends and forming methods bending and bend formation are important factors when it comes to calculating bend deduction which is the total elongation for a particular type of bend. Just that the leaf brake can serve a shop well where sheet metal bending isn t an everyday job.
