Sheet Metal Bending Calculation Software

This is done through the application of force on a workpiece.

Sheet metal bending calculation software.

Transition patterns available flat pattern segments lobsterback bend elbow. This page also includes a link to a on line sheet metal bend allowance calculator. We will start by calculating the bend allowance. Unfortunately sheet metal bending is not always going to be the same in every shop.

Sheet metal development calculator is a really simple tool for calculation of development of a sheet metal part. The bend allowance is the amount of the neutral axis that bends. In the example above it is indicated by a dashed blue line. After bending the sheet we need to do some measurements as shown in figure 2.

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. For example if the value of k factor for given material thickness and bending machines is known. Although it is an option for calculating a bend in some cad programs such as solid works it is not often referred to in the actual manufacturing process since. Sheet metal flat length can be calculated using cad softwares.

It is an integral and indispensable part of sheet metal bending operations that will not only automate and speed up the numerous repetitive calculations and drafting but also help you in achieving the same with the maximum degree of accuracy and efficiency thereby saving labor. Therefore using k factor there is no need to calculate sheet metal flat length manually. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Most sheet metal materials will conform to the calculations.

In the example above it is indicated by a dashed blue line. You only have to insert interior angle flange lengths k factor inside radius and material thickness. 90 degrees bend angle. Many software packages like solid works inventor and solid edge will let you incorporate a bend allowance chart into its calculations when developing flat patterns.

The force must exceed the material s yield strength to achieve a plastic deformation. From there we can calculate the k factor and the bend deduction. K factor in sheet metal bending is a constant that is used to calculate sheet metal flat length. Figure 2 illustrates the sheet that is bent with the bend angle of 90 degrees.

Cells on the right will output the desired values. Bending is one of the most common sheet metal fabrication operations.
