sheet metal flat length calculation formula Bend deduction (BD) is a critical factor in sheet metal fabrication, used to calculate the flat pattern length of a sheet metal part. It accounts for the material that is displaced during the bending process. Generally, metal conduits need to be secured within 36 inches from an electrical box and at seven-to-10-foot intervals. PVC conduit needs to be secured more often every three to five feet depending on size. Flexible conduits need to be secured 12 inches from boxes and every 4-1/2-feet thereafter.

Lt: Total unfolded length of the sheet metal part. A and B: Lengths of the two flanges adjacent to the bend. BD: Bend deduction value. Calculation of Bend Deduction. The bend deduction formula is used to determine the flat length of a sheet metal part before it is bent. The formula is as follows: Lt=A+B−BD. Where:
Let’s put an example with real measurements to do the calculation; L-shaped metal sheet profile. 25 + 30 + 3,1415/2 x (3 + 0,93) = 61,17 m/m will be the development of the sheet. U shape. Formula: Development = Flat face A + Base + .Sheet Metal Calculations There are many different methods which sheet metal designers and shops employ to determine the flat length of sheet stock which will give desired dimensions on the finished bent part. Some of these methods are simply "rules of thumb" which individuals use based on experience. Often these rules of
Calculation Formula. The K Factor is calculated using the formula: \[ K = \frac{D}{T} \] . signifies the thickness of the sheet metal. Example Calculation. For instance, if the distance from the inside radius of the bend to the neutral bend line (D) is 5 mm and the thickness of the sheet metal (T) is 2 mm, the K Factor would be calculated as . A fundamental principle derived from the neutral layer concept is that the unfolded (flat pattern) length of a bent sheet metal part equals the length of the neutral layer. This can be mathematically expressed as: Unfolded length = straight length A + straight length B + arc length C. Where: A and B are the straight sections of the part
