4.13 Pallet Management

Function
Pallet table management is a machine-dependent
function. The standard functional range will be described
below. Refer to your machine manual for more
information.
Pallet tables are used for machining centers with pallet changers: The
pallet table calls the part programs that are required for the different
pallets, and activates datum shifts or datum tables.
You can also use pallet tables to run in succession several programs
that have different datums.
Pallet tables contain the following information:
PAL/PGM (entry obligatory):
Identification for pallet or NC program (select with ENT or NO ENT)
NAME (entry obligatory):
Pallet or program name. The machine tool builder determines the
pallet name (see Machine Manual). The program name must be
stored in the same directory as the pallet table. Otherwise you must
enter the full path name for the program.
PRESET (entry optional):
Preset number from the preset table. The preset number defined
here is interpreted by the TNC either as a pallet datum PAL in the
PAL/PGM) column or as a workpiece datum (PGM entry in the PAL/PGM)
line.
DATUM (entry optional):
Name of the datum table. The datum table must be stored in the
same directory as the pallet table. Otherwise you must enter the full
path name for the datum table. Datums from the datum table can be
activated in the NC program with Cycle 7 DATUM SHIFT.
