K Factor Table For Sheet Metal

K t t why the k factor cannot exceed 0 5.

K factor table for sheet metal.

Sheet metal flat length can be calculated using cad softwares. Definition of the k factor. For example if the value of k factor for given material thickness and bending machines is known. The k factor depends on many factors including the material the type of bending operation coining bottoming air bending etc the tools etc.

When you select k factor as the bend allowance you can specify a k factor bend table. The bend allowance bend deduction of the sheet metal specified in k factor by configuring and utilizing a sheet metal gauge table we can speed up the process of selecting the correct wall thickness based on gauge value and selecting the correct bend radius based on available tooling we can also automate the process of selecting the appropriate k factor. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The line where the transition from compression to stretching occurs is called the neutral axis.

The solidworks application also comes with a k factor bend table in microsoft excel format. The part of the material that bends. 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. The location of the neutral axis varies and is based on the material s physical properties and its thickness.

K factor k factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part. Calculate k factor bend allowance and y factor for sheet metal bending. The k factor is the ratio of the neutral layer position thickness t of the sheet metal to the overall thickness of the sheet metal material t i e. Therefore using k factor there is no need to calculate sheet metal flat length manually.

The k factor is defined mathematically as t mt where t is the neutral axis location and mt is the material thickness. To figure this out the reason why the k factor can t exceed 0 5 you first need to know what the k factor is. K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length. 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 k factor in sheet metal working is the ratio of the neutral axis to the material thickness. Because of the specific properties of any given metal there is no easy way to calculate that value perfectly hence the chart in figure 2. The k factor is usually somewhere between 0 3 and 0 5. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.
