K Factor Table Sheet Metal

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.

K factor table sheet metal.

When you select k factor as the bend allowance you can specify a k factor bend table. And now the k factor. The part of the material that bends. K factor is a ratio that represents the location of the neutral sheet with respect to the thickness of the sheet metal part.

When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1. Now let s see how we can obtain these values for a specific sheet. The k factor is defined as the ratio between the material thickness t and the neutral fibre axis t i e. For each sheet metal part you can either specify a k factor or use the default one.

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

Changing the k factor for a sheet metal part. As i mentioned in my last post you need to do some tests to calculate these values for a specific sheet. And is typically between 0 3 and 0 5. The location of the neutral axis varies and.

The problem with a solidworks sheet metal bend table is that it can only control the bend allowance bend deduction or k factor but the thickness and radius is still free to be changed manually. 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. The value must lie in the range 0 1 since the neutral surface is located. Calculate k factor bend allowance and y factor for sheet metal bending.

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. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. 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. 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.
