Material thickness mt the gauge of the material in decimal form.

Developed length of bent sheet metal.

Die edge radius in. Whereas the outer surface is stretched. Bend allowance ba the amount of added to the sum of the two leg lengths to obtain the flat pattern length. Sheet metal flat length can be calculated in the following three simple steps.

60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them. Bending allowance is the input for calculating developed sheet metal size. The diagram shows one such mechanism. We are going to review three bending scenarios with three different bending angles.

These tests include bending some samples and then do some measurements and calculations. When sheet metal is bend the inside bending surface is compressed. For example when sheet metal of length l is bend. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.

Dimensions of the two legs of the bent part. Geometry of tooling imposes a minimum bend dimension. As a result overall sheet length increases. The formula for this is sb 43r 1 372t r the radius on the inside curve of the bend.

Cells on the right will output the desired values. You can use this sheet metal flat pattern calculator to calculate this increase in length. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. Bend deduction bd the amount removed from the sum of the two flange lengths to obtain a flat pattern.

Ultimate tensile strength psi. See the snap below. T the thickness of the sheet or plate 2 000 2 000 i0 125 developing the flat blank length for the above drawn part. If the value of sheet metal k factor and bending flange length is known.

Calculate the value bend allowance for required sheet metal bend by using below formula. Refer to the chart for values for folder as well as various press brake tooling combinations. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Bend allowance ba π 180 r k t a.

Bend angle b the inside angle between the two legs or flanges of a bend. 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.
