Sheet Metal Bend Radius Calculator

Material thickness microform bend deduction.

Sheet metal bend radius calculator.

Sheet metal calculator bend allowance equations and calculator. Cells on the right will output the desired values. The most important consideration when bending metal on a brake is the minimum bend radius. This page also includes a link to a on line sheet metal bend allowance calculator.

The material thickness will be measured in decimal form not by the gauge number. Bend radii minimum bend sizes. Therefore the bend allowance added to the flange lengths is equal to the total flat. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Punch edge radius in. Bend allowance calculator tells you the amount of metal to add. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. Bend allowance sheet metal change inlength due to bending operation calculator.

Then input the bend angle to get the arc length bend allowance and bend deduction. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Precision sheet metal fabrication request a quote.

Input material thickness and and inner radius to get the data of k factor y factor neutral layer. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Use this document to choose values that are both manufacturable and meet your needs. Die edge radius in. Inside bend radius r inches must be greater than 90 and less than 180 degrees. Most sheet metal materials.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. 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. Most sheet metal materials will conform to the calculations. Online bend deduction calculator.
