Blank length computation
After postprocessing, the controller calculates the developed length of your product and the
bend allowance.
Important for the developed length calculation and the bend allowance is the inner radius of
the bends.
For each of these computations a correction factor can be programmed (RF and AF).
Radius factor blank length . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . RF=
The computed inner radius is multiplied by this factor to correct the total developed
length of the product. The initial value of RF is 1.
Radius factor X-axis position . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . AF=
The computed inner radius is multiplied by this factor to correct the X-axis position in
order to have a correct product dimension after each specific bend (bend allowance).
This factor can be checked by making a product with just one bend and a certain product
dimension e.g. 100 mm (outer dimension). See figure 2.s.
The controller computes the X-axis position necessary to obtain L=100 as shown in figure 2.s.
The accuracy of the length L is dependent on the material parameters like thickness, strength
and kind of material. In order to have a correction possibility with the radius factor AF you can
optimise this computation.
RF and AF do not influence each other. It is recommended that first you optimise the AF factor
