Bending Factor In Sheet Metal

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

Bending factor in sheet metal.

Just that the leaf brake can serve a shop well where sheet metal bending isn t an everyday job. The part of the material that bends. 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. 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.

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. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Bend allowance and k factor. Calculate k factor bend allowance and y factor for sheet metal bending.

Sheet metal flat length can be calculated using cad softwares. 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. The line where the transition from compression to stretching occurs is called the neutral axis.

Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line. 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. When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1.

K factor plays a key role in understanding the limits a material can handle during sheet metal bending. When metal is bent the top section is going to undergo compression and the bottom section will be stretched.
