User Data - Siemens SINUMERIK 802D sl Programming And Operating Manual

Key (rapid input $A_IN[]) for initiating an intermediate dressing process, program abort and
handwheel override (oscillation);
The keys must either be directly wired or laid to the NCK interface through the PLC. For the
oscillation, a stroke reversal must be initiated to immediately abort the oscillating motion, i.e.
the signals must be decoded in the PLC. After aborting and dressing, the part is again ap-
proached using 30 µm relief. For inclined plunge-cutting, the relief is calculated using the an-
gle to the Z axis.
For oscillation, the stroke reversal program control must be initiated by the PLC; for stroke
reversal, infeed is always done, irrespective of the type of infeed; furthermore, infeed is
automatically done depending on the type programmed for the oscillation reversal points.
Intermediate dressing upon key and program abort key are always operational during infeed;
keys for handwheel override and stroke reversal are operational for oscillation operations
only.
Cycle auxiliary subroutines
The cycle package includes the accessory subroutines that are required for the machining
cycles and for setup.

● CYCLE418(INT _N_SITZ)
● CYCLE431(INT _ZU_ART)

User data

The user data is internally processed in the grinding cycles. They are stored in the program
manager of the control system (in the directory \DEF) as a definition file and remain stored
even when the control is switched off and on.
Description of the user data
The parameters included in the definition files are described as follows:
Grinding
Programming and Operating manual, 06/2006, 6FC5398-4CP10-0BA0
Cycle for dressing on key. Called up during the grinding cycles. After the dressing, the
further finishing takes place with 30 µm of relief
_N_SITZ - Seat number of the operation comes from overlaid cycle for seat compensation
_AKT_ABR_P - Current dressing program name (currently "" ) the dressing parameters of
the tools are used
Cycle for program abort. A return position is approached, the tool and the coolant are
switched off in order to make measurements or checks of the workpiece. After NC start,
the further finishing takes place with 30 µm of relief If necessary, the cycle must be
adapted to the machine by the machine manufacturer.
_N_SITZ - Seat number of the operation comes from overlaid cycle for seat compensation
For oscillation and multiple plunge-cutting, the cycle is used to control the infeed in the
reversal points and to thereby activate the infeed axis or the oscillating axis. (Use in the
cycles CYCLE411 and CYCLE415)
_ZU_ART - current type of infeed (-1/0/1 corresponds to left/both sides/right)
