Sheet metal bend radius calculator.

Bend allowance sheet metal change inlength due to bending operation calculator. The most important consideration when bending metal on a brake is the minimum bend radius. Cells on the right will output the desired values. Inside bend radius r inches must be greater than 90 and less than 180 degrees.

Then input the bend angle to get the arc length bend allowance and bend deduction. Most sheet metal materials will conform to the calculations. 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 formula example.

Input material thickness and and inner radius to get the data of k factor y factor neutral layer. Bend allowance calculator tells you the amount of metal to add. Online bend deduction calculator. Bend radii minimum bend sizes.

Therefore the bend allowance added to the flange lengths is equal to the total flat. Use this document to choose values that are both manufacturable and meet your needs. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Most sheet metal materials.

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. Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Punch edge radius in. Sheet metal calculator bend allowance equations and calculator.

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

Die edge radius in. Microform precision llc 4244 south market. Material thickness microform bend deduction. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

This page also includes a link to a on line sheet metal bend allowance calculator. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.
