bend allowance


Bend allowance is the length of the neutral axis of a bent part 1 2 3 and is calculated as BA = angle × (radius + K-factor × thickness). 1 2 3 The K-factor or stretch factor of the material 1 2 3 and the angle 1 2 3 can be in radians or degrees, depending on the formula. The bend allowance is the amount of metal to be added to the total layout 4 and is equal to the difference between the unfolded length (L) and the sum of the flange lengths (L1 and L2). 5

Summary The Bend Allowance is defined as the material you will add to the actual leg lengths of the part in order to develop a flat pattern. The leg lengths are the part of the flange which is outside of the bend radius. In our example below a part with flange lengths of 2” and 3” with an inside radius of .

Summary The bend allowance describes the length of the neutral axis between the bend lines, or in other words, the arc length of the bend. Therefore, the bend allowance added to the flange lengths is equal to the total flat length.
