You described a rough rule to find a steel’s minimum bend radius: Divide 50 by the material’s reduction percentage, as specified by the material supplier, subtract by 1, and then multiply by the plate . The bending deduction in Solidworks is only used for the calculation of 90-degree bends in sheet metal. However, it can also be used for the calculation of non-90-degree sheet metal unfolding, but the bending deduction value for non-90-degree bending needs to be used according .
Once the material thickness and bend radius are known, the bend allowance can be calculated using empirical formulas. One common formula is the K-factor method, which considers the material type and the bend radius. The K-factor is a constant that varies with the material and bend radius. For example, for mild steel, the K-factor for a bend . It is important not to fall below certain values for the bend radius. These values are determined by the degree of deformation of the external fibres of the sheet, and depend on its thickness. Determining the minimum bend radius (ri) is particularly important. Based on experimental data, the minimum bend radius (ri) can be determined as follows: Here you can specify many of the sheet metal specific properties including bend radius, K-factor, and bend relief dimensions. These can be fixed values or formulas based on the material thickness. (Note: you can find all of this information for your chosen material and thickness in our bending calculator as well.) Factors Influencing the Minimum Bend Radius. The minimum bend radius of the sheet metal is affected by several factors, each of which is of specific importance in determining the most desirable degree of bend that would prevent collapse or paper deformation. tAng factors include:. Material Type: Different materials have varying levels of ductility and tensile strength, .
In sheet metal fabrication, curving sheets according to a specific bend radius is one of the most common operations used to create flanges, curls, seams etc.Moreover, bending imparts much strength to the sheet metal compared to their flatter counterparts. For example, an aluminium sheet bent into a V cross section will be much stiffer and stronger than the same flat .One typical process where bending radius is important is sheet metal working. A common method of sheet bending uses a “press brake” that presses the sheet between the upper die called the punch and the lower die. In addition to the V-dies shown in the figures below, various types of dies are used according to the bending shape and material. .Bend Radius (mm): Enter the radius of the bend Bend Angle (degrees): Enter the angle at which the metal is to be bent K-Factor: Enter the K-factor, a value that represents the material's behavior during bending (commonly around 0.33).

Calculating the bend radius for different metals involves understanding the material properties and the specific parameters involved in the bending process.Bend radius is critical in metalworking, particularly in the fabrication of components such as sheet metal parts, where excessive bending can lead to material failure.Our supplier has already been working with us for decades at that point, so all we really did was the exterior dimensions of the sheet metal, and the call-outs for thru/countersunk holes. We never specified the bend radius, simply shaved down the milled-end where the bend radius was too large and didn't fit (basically never)
2. Placing holes, slots, notches or any other features too close to bend radius. Placing features too close to the bend radius or even at the edge of the die opening will distort the features and the part may no longer be able to hold necessary hardware near the bend radius. How to Avoid. Features should be placed no closer than three times the . The bend radius is the distance from the neutral axis of the sheet metal to the inside edge of the bend. A larger bend radius requires a larger bend allowance as the material has to stretch more to accommodate the bend. Conversely, a smaller bend radius necessitates a smaller bend allowance. Thickness of the Sheet Metal. The thickness of the .
In essence, it’s the inner radius of the bend that determines how tight a curve can be formed in the sheet metal. 2. Sheet Metal Bend Radius Chart.
