Calculation Example. Bend allowance is important because it gives us the information to cut sheet metal to produce a bent metal piece accurately.
The total length increases, so it's essential to calculate the sheet metal bend deduction. Bend deduction is the difference between the total length of the flanges after bending and the total flat length. We discussed the bend allowance and bend deduction calculation in a previous article. The bend deduction is often confused with bend allowance. In software like SolidWorks, specify bend deduction or bend allowance values for sheet metal parts using a bend deduction table. Specify the K-factor value in its dedicated K-factor or bend allowance section. This approach enables more precise control over the sheet metal bending process. Consider Additional Bending Parameters: The following equation is used to determine the total flattening length when using the bend deduction value: L t = A + B – BD. Where: 𝐿 𝑡 is the total flat length.; 𝐴 and 𝐵 are the lengths of the two straight sections of the sheet metal before the bend (as shown in the figure).How to calculate the value of material shrinkage. With this free online tool we quickly get the sheet metal bend deduction, and therefore the sheet metal blank initial flat length, from the finished part measurements. You only have to insert interior angle, flange lengths, K factor, inside radius, and material thickness.
In order to develop the flat pattern we add .457” to 1.625” and 2.625” to arrive at 4.707”. As you can see the Bend Allowance and Bend Deduction are closely related below. Bend Allowance Calculator.
