C
YCLE WITHOUT BEND
The cycle without bend is used to move the axes and auxiliary functions
without moving the beam.
To program a cycle without bend:
Delete
the
field.
Program Y1 and Y2 at a value greater than that of the contact point
(CP).
The cycle proceeds as follows:
Descent
command
TDC output cut
End of bend impulse
Sequence
forward
Start of axes and auxiliary functions depending on the mode
TDC output activated
Control synchro impulse
Wait descent command
This cycle has been defined for re-arming the electrical cabinet for a new
bend.
P
UNCHING
To use punching tools on the pressbrake, it is essential to know the exit value
of the punch.
Then the DNC is to program in such a way that the bottom dead centre corre-
sponds to this exit point.
If necessary, a fictitious tools pair can be programmed in order to adjust the
reference height such that the clamping point is just above the pressing up of
the punching tools.
To find these values:
Make a descent with the machine in adjustment mode
and the
DNC in
mode.
When the punch reaches its exit point, stop the descent and note the
position of the beam.
Delete
the
field.
Introduce this value in Y1 Y2.
Regulate the tool reference value as a function of the tools used.
