Calculate angle to form sheet metal.

Use the known k factor and the known inner bending radius to calculate the bending radius of the neutral line. But the most accurate way to find out k factor is reverse engineering of a small but same sheet metal sample piece. By doing so the sheet can be bent or stretched into a variety of complex shapes. Work piece the general term for the sheet metal part being bent.

The results give you a starting point for incorporating real world bending variables such as material type thickness springback and the parabola effect. Ultimate tensile strength psi. A bend greater than 90 but less than 180. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material.

Tolerances general dimensioning and tolerances of bends and sheet metal. So if you got k factor value now you can easily calculate bending allowance. Punch edge radius in. Sizing of a machine or available die width should allow for up to 20.

This estimator calculates a force representative of the pressbrake requirement for air bending. There are standard charts available with sheet metal design handbook for calculating k factor ideally it should be 0 5. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Die edge radius in. This type of angle can also be referred to as a square bend. The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail. 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.

Actual 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. Procedure is as below. Straight angle a geometry term for an angle which is equal to 180. Figure 1 if you know the included bend angle and the die width you can calculate the inside radius and length of the arc at a specific depth of penetration dp using your graphic calculator or online calculators like www handymath.

Right angles are the most common feature found in most sheet metal fabrication.
