Sheet Metal Development Length Calculation Online

K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length.

Sheet metal development length calculation online.

When sheet metal is bend the inside bending surface is compressed. To help with that we ve got our handy weight calculator here. The website for online development of sheetmetal parts and generation of dxf files of these sheetmetal parts possible without using cad software and within a very short space of time. As a result overall sheet length increases.

For example if the value of k factor for given material thickness and bending machines is known. Ultimate tensile strength psi. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. Transition patterns available flat pattern segments lobsterback bend elbow ellipsoidal dome head tee offset tee square and rectangle to round frustum cone.

With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements. You can use this sheet metal flat pattern calculator to calculate this increase in length. But the most accurate way to find out k factor is reverse engineering of a small but same sheet metal sample piece. Fill out the information below and it will tell you how heavy that piece of material is.

Metal gets heavy and whether you want to see how much shipping is likely to be or if your vehicle or back can handle it it s good to know what your order weighs. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Therefore using k factor there is no need to calculate sheet metal flat length manually. A preview of the sheet metal will be displayed once the requested parameters have been entered.

We are going to review three bending scenarios with three different bending angles. Die edge radius in. Punch edge radius in. Procedure is as below.

To find α calculate the difference between the unfold length before machining and the outside dimension after machining a b. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them. Whereas the outer surface is stretched. There are standard charts available with sheet metal design handbook for calculating k factor ideally it should be 0 5.

Sheet metal flat length can be calculated using cad softwares. Sheet metal development calculator is a really simple tool for calculation of development of a sheet metal part.
