Bending Factor In Sheet Metal

In sheet metal the k factor is the ratio of the neutral axis to the material thickness.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. The line where the transition from compression to stretching occurs is called the neutral axis. For example if the value of k factor for given material thickness and bending machines is known. 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.

Calculate k factor bend allowance and y factor for sheet metal bending. K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1.

Sheet metal flat length can be calculated using cad softwares. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e. 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. 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.

Just that the leaf brake can serve a shop well where sheet metal bending isn t an everyday job. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
