Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in Figure 1. We are going to review three bending scenarios with three different bending angles; 60, 90 and 120, and we will calculate K-Factor, Bend .To calculate the bend allowance, the K factor and the derived coefficient called the Y factor, insert the thickness and initial length of the sheet into the cells on the left. After bending the sheet, .When designing sheet metal with the Sheet Metal model feature, locate the Material > Bend Calculation option in the dialog. The dropdown options are: K Factor: A dimensionless factor representing the ratio of the neutral axis length . To enhance the readers’ understanding of basic concepts in sheet metal design calculation, the following points will be summarized and explained:. The definitions of the two bending algorithms: bend allowance and bend .
The variables in this formula include: S: Sheet thickness; r: Inner radius during bending; K: Width of the horizontal projection of the bending deformation zone; From the derivation process, it is essential to meet two additional conditions when using formulas (2) or (3) to calculate bending force: the width-to-thickness ratio (V/S) must equal 9, and the radius-to-width ratio must equal .
To help you achieve the highest standard of fit and function, here's our top 5 sheet metal design formulas you need to consider for bending. Skip to content. Want to talk to a human? Our team is standing by! (603) 883 1510. . (2) Bending radius calculation formula. Sheet metal bending parts require a bending radius r at the bend. Typically, the blueprints for sheet metal parts have clear markings for the bending radius. The final size after bending is determined by the punch radius r 0 and the amount of springback r, i.e., r = r 0 + r. 90 Degrees Bend Angle. Figure 2 illustrates the sheet that is bent with the bend angle of 90 degrees. We will start by calculating the Bend Allowance. From there we can calculate the K-Factor and the Bend Deduction. After bending the sheet we need to do some measurements as shown in Figure 2.
Bend Radius - As a rule, inside bend radius should be equal to material thickness. When the radius is less than recommended, this can cause material flow problems in soft material and fracturing in hard material. Bend Relief - When a bend is made close to an edge the material may tear unless bend relief is given. Figure "A" shows a torn part.
The roll_bending_allow_din function retrieves the K-factor from the tool table and uses the Sh_calculate_bend_allowance_DIN formula. This formula handles bends that have angles greater than 180 degrees. . Sample allowance tables are provided in the sha_demoshop.lsp file supplied with Creo Elements/Direct Sheet Metal. Sample formulas for . needed as in the “standard” formula below. In fact, the “standard” formula is the radian formula plus a “built in” angle conversion from radian measure to (base 360) degrees, shown in the “Common Formula”. K R A L=? T BEND ALLOWANCE FORMULA (FOR ANGLE IN RADIANS) L= A (R+KT) A = ANGLE (RADIANS) R = BEND RADIUS Bending is one of the most common sheet metal fabrication operations. Also known as press braking, flanging, die bending, folding and edging, this method is used to deform a material to an angular shape.. This is done through the application of force on a workpiece. The force must exceed the material’s yield strength to achieve plastic deformation.
