Bend methods:
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 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
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.
V0812, 2.6
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.
