Bend allowance is a critical factor in the sheet metal bending process, particularly for materials like aluminum. It accounts for the material stretch that occurs during bending, ensuring accurate final dimensions. Here, we will discuss the specific formula used for aluminum plates and its application.Sheet metal bending is a forming operation where sheets are deformed plastically to change their shape. During sheetmetal bending, the material is stressed beyond its yield strength but below the ultimate tensile strength. After bending a sheet metal part, the total length of sheet metal is more than the flat length.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, bend radius, bend angle, and .
