As this happens you gain a small amount of total length in your part.

Bend allowance for aluminum sheet.

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. Bend allowance and k factor. The bend table approach is probably the most accurate approach for calculating bend allowance.

The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend. Calculate unfold size with bend allowance chart. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Therefore the bend allowance added to the flange lengths is equal to the total flat.

It exists for a reason. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. Figure 2 illustrates the sheet that is bent with the bend angle of 90 degrees. 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 allowance is a measure of how much extra material is required to accommodate a bend in sheet metal this is a function of the bend angle bend radius thickness of the material and a variable called the k factor bend allowances vary based on the angle of the bend the type and thickness of the material and the method used to create the bend. If you design your bent sheet metal parts in cad software that has a special sheet metal environment use it. From there we can calculate the k factor and the bend deduction. V die width is 6 8 times the plate thickness.

Most sheet metal materials will conform to the calculations. 90 degrees bend angle. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.

We will start by calculating the bend allowance. This page also includes a link to a on line sheet metal bend allowance calculator. After bending the sheet we need to do some measurements as shown in figure 2. L unfold length a outside size b outside size k k factor none 90 bend unfold according to the neutral layer the distance from neutral to sheet inner side is t 3 inner r can refer to the above chart.

Bend forming 0 l a b 0 43t t thickness deduction 0 43t. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.
