2.3. Bend programming
2.3.1. Introduction
The parameters of one bend are divided over 2 screen pages. The bend number, product
number and drawing number are displayed in the top row on the screen.
2.d
The parameters below the line are corrections. They are not necessary when programming a
product, but are used to correct the machine behaviour during production. They are described
in chapter 6.
2.3.2. Bend parameters - first page
Method . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..BM
Select the required bending method. The control supports 2 methods:
0 = Air bend
1 = Bottoming
Bend methods:
Use the key ‘change view’ to switch to another page
with bend parameters.
When this key is pressed again, a screen with zoomed
values appears.

V0608, 2.6
Note:
When bottoming operation is selected, the end of bend position of the Y-axis beam is
depending on the working tonnage. If however the force is sufficient for the beam to go to the
calculated Y-axis end of bend position, the beam stroke will be limited by the position value.
Angle . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .α
The required angle of this bend. This parameter only appears if angle programming is
selected with the parameter 'Angle sel.' and the bend method is an air bend.
Bend position . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Y
The required Y-axis position for this bend. This parameter only appears if absolute
programming is selected with the parameter 'Angle sel.' This parameter also appears if
the bend method is bottoming and/or flattening.
Opening . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .DY
This parameter results in a certain gap opening between the punch and the die after the
bend. A positive value is the gap opening above Mute, a negative value below Mute.
When you want to limit the handling time of the product you can program a small
positive or a negative value.
Repetition . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .CY
0 = bending is skipped.
1 through 99 = the number of times this bending will be repeated.
X-axis . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .X
Backgauge position. When a negative sign is programmed this backgauge dimension is
an incremental dimension. The incremental dimension is subtracted from the actual X-
axis position. Therefore this parameter can also be used as a chaining measure.
Retract . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .DX
Retract distance of backgauge during the bending. The "backgauge retract" is started at
the pinching point of the sheet.
Auxiliary axis. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .R/Z/Aux.
If you have one or more auxiliary axes (for instance a R-axis, Z-axis or part support) the
air bend The sheet is bent to the programmed angle
by bringing the punch to the required depth.
The control calculates the required Y-axis
position to obtain the programmed angle.
bottoming The sheet is bent by squeezing the sheet
between the punch and the die. The control
assumes the bottom of the die as required Y-
axis position.

V0608, 2.7
parameters of these axes appear here.
2.3.3. Bend parameters - second page
2.e
This page contains the additional parameters of a bend.
Force. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..P
The required force during pressing (auto computed).
This force is precomputed from the bend properties Material, Thickness, Bending length
and the V-opening of the die.
Speed . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..V
Working speed (pressing speed). Initially, the value for this parameter is copied from the
parameter ‘pressing speed’ in the programming constants menu.
Dwell time. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..T
Holding time of punch at bending point.
Decompression . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..DC
Decompression stroke after bending to release the working pressure
Decomp speed . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..BS
The decompression speed is the programmable speed which is active during the
programmed decompression stroke.
Code . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ..CX
Programmable parameter which determines when the parameter values for the next
bending will be active. The possibilities are:
0 = Bending number change (step change) at end of decompression (next bend

V0608, 2.8
parameters active).
1 = Step change at muting position when the beam moves in opening direction.
2 = Step change at upper dead point.
3 = Step change at upper dead point without movement of any axis and the control goes
to "stop".
4 = Step change if C-input signal becomes active, without movement of the beam. When
you still have a beam movement there will be no retract function of the backgauge
performed. See also code 5.
5 = Step change if C-input signal becomes active and the beam is in the upper dead
point. Now you may move the beam and the retract function of the backgauge will be
performed.
10= Step change at end of decompression with the Y-axis beam waiting at the pinching
point until the backgauge is at the retract position.
11= Step change at mute position when the beam moves in the opening direction, with
the Y-axis beam waiting at the pinching point until the backgauge is at the retract
position.
12= Step change at upper dead point, with the Y-axis beam waiting at the pinching point
until the backgauge is at the retract position.
13= Step change at upper dead point without movement of any axis. The Y-axis beam
will wait at the sheet clamp point until the backgauge is at the retract position. After the
bending with this code, the control goes to "stop".
15= Step change if C-input signal becomes active and the beam is in the upper dead
point. The beam may be moved but not necessarily. The Y-axis beam will wait at the
sheet clamp point until the backgauge is at the retract position.
The not mentioned CX-values have no meaning.
Delay time . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .TX
Programmable delay time before step change (0-30sec).
Parallelism . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Y2
Difference of left- and right hand side cylinder (Y1 and Y2). When positive, right hand
side lower. When negative, right hand side higher. The programmed value is active
below the clamping point.
