This is not easy since the exact location of the bend line is really not know. The length of the neutral axis is calculated as a bend allowance, taken atpercent of the material thickness For a slot or hole > 1 diameter then the minimum distance D = T + R (see fig. C) Form height to thickness ratio – To determine the minimum form height for sheet metal use the following formula: D = T + R (see below) The height can be less but it required secondary operations and is far more costly Where A= (– Bend Included Angle) If the inside radius is equal to t or 2t, or between t and 2t, the bend allowance is calculated by interpolating the bend allowance values from the two formulas mentioned above. Besides, to calculate this bending allowance, you can also use the following formula: B A = A × π × (R + K × T) BA Figure– Measuring the flange lengths up to a bend is not practical in practice Sheet Metal Bending Calculation. You will Bend allowances are calculated using a K-factor as follows: BA= (R + KT) A/ where: BA = bend allowance R = inside bend radius K = K factor, which is t T T = material Sheet MetalBend AllowanceIntroduction. The Bend Allowance Formula takes into account the geometries of bending and the properties of your metal to determine the Bend Allowance. Bend Allowance (BA) BA = [ (× Inside radius) + (× Material thickness)] × Bend angle, which is always complementary. Bend allowance, while being oftentimes tricky to determine for all cases, is fairly easy to predict and calculate for many standard circumstances Bending a known length of sheet metal is easy, but to calculate the Bend Allowance (and therefore the K Factor), the lengths of L1 and L2 must be measured. Bend allowance is a term which describes how much material is needed between two panels to accommodate a given bend. nT Determined experimentally Theoretically, r= % reduction in Bend Allowance Formula. The bend allowance method describes the flattened length of the part (LT) as the sum of the lengths of each of the flat portions of the part plus the length of the flattened bend Form height to thickness ratio – To determine the minimum form height for sheet metal use the following formula: D = T + R (see below) The height can be less but it required Sheet Metal Bending Minimum bend radius: expressed as an integer (n) multiple of the sheet thickness T i.e.
