Sheet metal bend radius calculator.

Bend formula example. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. 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. Microform precision llc 4244 south market.

Online bend deduction calculator. Most sheet metal materials. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Sheet metal calculator bend allowance equations and calculator.

Inside bend radius r inches must be greater than 90 and less than 180 degrees. You only have to insert interior angle flange lengths k factor inside radius and material thickness. The most important consideration when bending metal on a brake is the minimum bend radius. Cells on the right will output the desired values.

Bend allowance calculator tells you the amount of metal to add. Die edge radius in. Material thickness microform bend deduction. This page also includes a link to a on line sheet metal bend allowance calculator.

Most sheet metal materials will conform to the calculations. Punch edge radius in. Use this document to choose values that are both manufacturable and meet your needs. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Therefore the bend allowance added to the flange lengths is equal to the total flat. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. The material thickness will be measured in decimal form not by the gauge number. Input material thickness and and inner radius to get the data of k factor y factor neutral layer.

Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Ultimate tensile strength psi. Bend allowance sheet metal change inlength due to bending operation calculator.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Then input leg length a and b to get the flat size of the sheet.
