K Factor Sheet Metal 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.

K factor sheet metal table.

When you select k factor as the bend allowance you can specify a k factor bend table. And now the k factor. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. In sheet metal the k factor is the ratio of the neutral axis to the material thickness.

Calculate k factor bend allowance and y factor for sheet metal bending. Changing the k factor for a sheet metal part. The value must lie in the range 0 1 since the neutral surface is located. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e.

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 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 solidworks application also comes with a k factor bend table in microsoft excel format. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations.

To change the k factor for a sheet metal part select the root node in the mechanical browser and type a value in the k factor field. The location of the neutral axis varies and. For each sheet metal part you can either specify a k factor or use the default one. K factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part.

The part of the material that bends. When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. So if the thickness of the sheet was a distance of t 1 mm and the location of the neutral axis was a distance of t 0 5 mm measured from the inside bend then you would.

The line where the transition from compression to stretching occurs is called the neutral axis. 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.
