Therefore the bend deduction equals the difference between the mold line lengths and the total flat length.
Sheet metal bend relief calculator.
The bend allowance is the amount of the neutral axis that bends.
Below is our simple bend allowance calculator it works by inputing the material thickness bend angle inside radius and k factor.
Most sheet metal materials will conform to the calculations.
Geometry of tooling imposes a minimum bend dimension.
Sheet metal calculator bend allowance equations and calculator.
Refer to the chart for values for folder as well as various press brake tooling combinations.
Note that the bend angle is the excluded angle not the included angle.
You also have access to our team of knowledgeable engineers to optimize part designs and user friendly online resources.
It simply processes these variables through the equations we will discuss below.
In the example above it is indicated by a dashed blue line.
Most sheet metal materials will conform to the calculations.
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 bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
Cells on the right will output the desired values.
The bend allowance added to the flange lengths is equal to the total flat length of the part.
Bend allowance calculator the bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length.
This page also includes a link to a on line sheet metal bend allowance calculator.
Our sheet metal fabrication process unlike traditional sheet metal shops we have infinite capacity and an easy to use online quoting system ensuring on time shipment every time whether you need a single part or 500 parts.
You only have to insert interior angle flange lengths k factor inside radius and material thickness.
The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.
The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal.
In the example above it is indicated by a dashed blue line.
