13.1 Pallet management
Application
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 reference points.
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 your machine tool 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
 PALPRES (entry optional):
Preset number from the pallet preset table. The TNC interprets the
preset number defined here as pallet datum (PAL entry in PAL/PGM
column). You can use the pallet preset to compensate mechanical
differences between the pallets. A pallet preset can also be
activated automatically when a pallet is added
 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 entry in
the PAL/PGM column) or as a workpiece datum (PGM entry in PAL/PGM
line). If there is a pallet preset table active on your machine, then use
the PRESET column only for workpiece datums
 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
Pallet table management is a machine-dependent
function. The standard functional range is described
below. Refer to your machine tool manual for more
information.
