Sheet Metal Bend Radius Calculator

Material thickness microform bend deduction.

Sheet metal bend radius calculator.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Bend allowance sheet metal change inlength due to bending operation calculator. Bend radii minimum bend sizes. The material thickness will be measured in decimal form not by the gauge number.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. Ultimate tensile strength psi. Inside bend radius r inches must be greater than 90 and less than 180 degrees. Input material thickness and and inner radius to get the data of k factor y factor neutral layer.

Then input leg length a and b to get the flat size of the sheet. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. Microform precision llc 4244 south market. Use this document to choose values that are both manufacturable and meet your needs.

This page also includes a link to a on line sheet metal bend allowance calculator. Bend allowance calculator tells you the amount of metal to add. The most important consideration when bending metal on a brake is the minimum bend radius. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Precision sheet metal fabrication request a quote. Most sheet metal materials. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Online bend deduction calculator.

Punch edge radius in. Most sheet metal materials will conform to the calculations. Therefore the bend allowance added to the flange lengths is equal to the total flat. Bend formula example.

Die edge radius in. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Then input the bend angle to get the arc length bend allowance and bend deduction. Sheet metal calculator bend allowance equations and calculator.
