Sheet Metal Bending Calculation Software

In the example above it is indicated by a dashed blue line.

Sheet metal bending calculation software.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. 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. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Figure 2 illustrates the sheet that is bent with the bend angle of 90 degrees. From there we can calculate the k factor and the bend deduction. Sheet metal calculator bend allowance equations and calculator. Sheet metal development calculator is a really simple tool for calculation of development of a sheet metal part.

The force must exceed the material s yield strength to achieve a plastic deformation. 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. After bending the sheet we need to do some measurements as shown in figure 2. Most sheet metal materials will conform to the calculations.

The bend allowance is the amount of the neutral axis that bends. This page also includes a link to a on line sheet metal bend allowance calculator. 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. Cells on the right will output the desired values.

90 degrees bend angle. 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. Unfortunately sheet metal bending is not always going to be the same in every shop. Bend o matic is a revolutionary professional software package to determine initial unfolded length.

We will start by calculating the bend allowance. Bending is one of the most common sheet metal fabrication operations. Transition patterns available flat pattern segments lobsterback bend elbow. In the example above it is indicated by a dashed blue line.

Therefore using k factor there is no need to calculate sheet metal flat length manually. Sheet metal flat length can be calculated using cad softwares.
