5.4.2. Assignments - general
Optimisation degree
Range 1-5.
The number of alternatives to be computed for each bend must be entered here.
The higher this number the more alternatives are to be examined by the control, so the
longer the computing time will be.
Front extend ratio
Range 0.01 - 1.0.
This is the ratio of the minimum allowable length of your product which extends in front
of the press to the total blank length of the product. You must have a minimum length of
your product in front of the press to be able to handle the product.
Front extend ratio accept
Comply If Possible:
This means that when possible the computer tries to comply to the front extend ratio and
only when this will result in no solutions to be found it will accept that the length in front
is smaller than the specified ratio.
Comply Always:
The computer will always comply to the front extend ratio. This may result in no
solutions to be found.
Radius factor
Range 0.1 - 2.0.
The computed radius of a bend is multiplied by this factor for correction purposes. This
correction affects the X-axis position and the computed blank length. The initial value of
RF is 1.
The control computes the X-axis position necessary to obtain L=100 as shown in the figure
below. 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 RF
you can optimise this computation.
Tool length tolerance
The tool length may be shorter than the length of the bendline.
The maximum allowed difference between the tool length and bend length can be
programmed here. Tool length tolerance may influence your bend sequence: if the
