The setback formula in sheet metal is used to calculate the distance between the outside edge of a flat blank and the point where the bend will occur after forming. The exact formula depends on the geometry of the bend and the material being used. One common formula for setback is: Setback = (π/180 .The mold line lengths are the distances measured to the outside mold line and are equal to the flange lengths plus the setback. The values of the setback, bend allowance, and bend deduction can be calculated from the sheet thickness, .
The sheet metal blank size is determined by considering factors like part dimensions, material thickness, bend allowance, stretch allowance, bend radius, minimum bend distance, material properties, K-factor, drawing ratio, .Using a Formula to Calculate the Setback SB = setback K = K-factor (K is 1 for 90° bends) R = inside radius of the bend T = material thickness Since all of the angles in this example are 90° angles, the setback is calculated as follows SB = K(R+T) = 0.2 inches NOTE: K = 1 for a 90° bend. For other than a 90° bend, use a K-factor chart. The bending allowance calculator provided below simplifies the process of calculating the bending allowance value, which is crucial for accurate sheet metal fabrication. Bend allowance is the length of the neutral axis between the bend lines, which helps in determining the correct blank size for a bent part.
Bend deduction (BD) is a critical factor in sheet metal fabrication, used to calculate the flat pattern length of a sheet metal part. It accounts for the material that is displaced during the bending process. This value is essential for ensuring that the final dimensions of .

FIGURE 1. Several terms are at the heart of any sheet metal bending operation, including the neutral axis, inside bend radius, outside setback (OSSB), and bend allowance (BA). You calculate the bend deduction by doubling the OSSB and subtracting the BA. While bending produced metal parts, it results in wrong size of bent edges. How to calculate K-Factor in Inventor for Sheet Metal part? What is Bend Allowance? More material is stretch when is compresses, which lead in part being longer after bendingThe setback is typically specified in engineering or design drawings to ensure that bends are made at the correct locations to achieve the desired geometry and fit of the sheet metal component. Setback Calculation and Formula. In the realm of sheet metal fabrication, setbacks are pivotal factors that influence the precision and quality of the .t = The thickness of the sheet or plate 2.000 2.000 I0.125 Developing the flat blank length for the above drawn part: Calculate the Setback and then subtract it from the sum of two outside dimensions as follows - Where r=.125 and t=.125, SB = .43 (.125) + 1.372 (.125).0538 + .1715.225 Then 2.000 +2.000 4.000 - .225 3.775 This is the length of .
We generated the following bend allowance chart using the sheet metal bend allowance calculator for steel, assuming the K-factor of 0.45, bend angle of 90 degrees, and inside radius of 0.05 inches (1.3 mm). The actual K-factor may depend on the type of bending operation, the thickness of the sheet, and the material. How do you calculate setback and bend allowance? More Than One Way to Skin a Cat For instance, in this article we have used the following for outside setback: OSSB = [Tangent (degree of bend angle/2)] × (Material thickness + Inside radius). . Since commercial sheet metal bending can be done with less concern for stresses caused during .
Sheet Metal Calculations . Calculate the length of the bend region after it is flattened out. . Bend deduction, also often referred to as setback (sometimes represented by setback divided by two), is simply a different means by which to represent the .

Has pre-entered densities for dozens of commonly-used metals and metal alloys like steel, aluminum, nickel, iron, copper, cadmium, gold, silver, etc. Calculate the weight of a steel beam, bar, tube, profiles, channels, or a .Formulas: Bend Allowance (BA) – The amount of added to the sum of the two leg lengths to obtain the flat pattern length. Bend Deduction (BD) – The amount removed from the sum of the two flange lengths to obtain a flat pattern. Material Thickness (MT) – The gauge of the material in decimal form. Bend Angle (B<) – The inside angle between the two legs or flanges of a bend.
Bending Springback Calculator. After a bending operation, residual stresses will cause the sheet metal to spring back slightly. Due to this elastic recovery, it is necessary to over-bend the sheet a precise amount to acheive the desired bend radius and bend angle. The final bend radius and bend angle can be approximated from the sheet thickness .
