Sheet metal calculator bend allowance equations and calculator. Cells on the right will output the desired values. Punch edge radius in. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Microform precision llc 4244 south market. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Bend radii minimum bend sizes. 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.

Use this document to choose values that are both manufacturable and meet your needs. 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. Online bend deduction calculator.

Inside bend radius r inches must be greater than 90 and less than 180 degrees. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. The material thickness will be measured in decimal form not by the gauge number. Die edge radius in.

Precision sheet metal fabrication request a quote. The most important consideration when bending metal on a brake is the minimum bend radius. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.

Most sheet metal materials. Then input leg length a and b to get the flat size of the sheet. Bend allowance calculator tells you the amount of metal to add. Then input the bend angle to get the arc length bend allowance and bend deduction.

This page also includes a link to a on line sheet metal bend allowance calculator. Material thickness microform bend deduction. Bend formula example. Ultimate tensile strength psi.

Most sheet metal materials will conform to the calculations. Therefore the bend allowance added to the flange lengths is equal to the total flat.
