The K factor formulation does not take the forming stresses into account but is simply a geometric calculation of the location of the neutral line after the forces are applied and is thus the roll up of all the unknown (error) factors for a given setup. The K factor depends on many factors including the material, the type of bending operation

Mar 09, 2018 · We bend lots of stainless, which in terms of hardness, is very similar to mild steel (a36/gr50/cq) If I were to start folding, I would use .125 and a K factor of .45 Jack K Dec 11, 2018


Detailed

Now, use Eqn.1 and you will get K factor. This K factor will be same for the actual product. Use this K factor value to calculate bending allowance for main product. Conclusion. For getting accurate output of sheet metal bending process you need to calculate accurate sheet metal developed length.

Sep 28, 2015 · Sheet MetalUnderstanding K Factor. SOLIDWORKS sheet metal tools are relatively straight forward, but may not be clearly understood. In sheet metal, there is a powerful bend constant known as the K Factor. It ultimately allows you to estimate the amount of stretch without knowing what type of material you are bending.


Detailed

ASTM A36 carbon steel is a carbon (non alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the as fabricated (no temper or treatment) condition. It has a very high electrical conductivity among the wrought carbon or non alloy steels in the database.


Detailed

AR400 is a specialty steel designed at the chemical level for improved wear resistance for very specific applications. The steel is relatively expensive to produce, costing much more than simple mild steels such as A36 or 1018. However, the steel's special properties make it the only choice for applications such as blades in bulldozers.


Detailed

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 K factor. Learn more about Bending.


Detailed

DISCLAIMERActual bending force is affected by many factors such as friction between the material and the die, material thickness, material strength variations, rolling direction of the steel, work hardening and other parameters. This estimator calculates a force representative of the pressbrake requirement for air bending. Sizing of a machine or available die width should allow for up to 20%


Detailed

• A factor K is used as a multiplier for converting the actual column length to an effective buckling length based on end conditions. The American Institute of Steel Construction (AISC) provides recommended effective length factors when ideal conditions are approximated. •

Sheet metal bend allowance calculator formula & step by step calculation to find the flat pattern length when a bend is dimensioned either from the centre of radius or a tangent point of radius or the outside tangent point of the radius on an acute angle bend. BA = [A x (π/180) (r + (K x T))].

The 2.0mm Stainless Steel Blank will be 96mm to give 50mm legs and a 0.27K factor ( I use 0.27324) The 2.0mm Mild Steel Blak will be 96.6mm to give 50mm legs & 0.46 K factor ( I use 0.46425) I’ve been using these K factors & bend radi like this since Inventor 10 and have not had a problem.
