Selecting bending support
Bending support is the movement of the BendMaster during the
bending process (tracking).
1. Select bending step.
2. Set the "low-pass filter":
− No filter :
During bending, the BendMaster moves exactly according
to the specified TruBend position. In some cases, this
can lead to abrupt BendMaster movements due to the
press beam regulation.
− Low :
The TruBend position settings are filtered somewhat to
ensure that the bending support proceeds less abruptly.
The movement of the BendMaster for moving the bend-
ing part is however slightly delayed in time, which
increases the possibility of a reverse bend on the bend-
ing part.
− Medium :
The TruBend position settings are filtered more strongly.
The bending support is smoothed to a greater extent and
the movements proceed more gently. The delay time of
the BendMaster compared to the bending part becomes
even longer.
− High :
The TruBend position settings are filtered to the maxi-
mum extent. The bending support is smoothed to the
maximum extent. The time delay of the BendMaster com-
pared to the bending part increases significantly. The
possibility of a reverse bend or of the cups being torn off
the sheet increases.
3. Press For all bendings if the settings are to apply to all bend-
ing operations..
Note
The averaging filter cannot be adjusted by personnel.
Setting the backgauge sensor system
The necessary backstop strategy can be set in the "Backgauge
sensor system" field. The default values originate from TruTops
Bend. The press beam is enabled for the bending motion once
the set parameters have been reached.
1. Select bending step.
2. Setting "backgauge sensors":
