13.1 Pallet management (option number
22)
Application
Pallet table management is a machine-dependent
function. The standard functional range is described
below.
Refer to your machine manual.
Pallet tables (
.P
) are mainly used in machining centers with pallet
changers. The pallet tables call the different pallets with the
corresponding machining programs and activate all defined datums
and datum tables.
Without a pallet changer you can use pallet tables to process NC
programs with different datums in sequence with just one press of
NC START
.
If you want to create or manage pallet tables, the
name of the file must begin with a letter.
Pallet tables contain the following information:
NR
: The control produces the entry automatically when new
rows are added. The entry is required for the entry field
Line
number =
of the
BLOCK SCAN
function.
TYPE
: Input is obligatory. The control differentiates between the
entries Pallet
PAL
, fixture
FIX
or NC program
PGM
. Select the
entries using the
ENT
key and arrow keys.
NAME
: Entry is obligatory. The machine tool builder specifies the
names for pallets and fixtures (observe the machine manual),
whereas you define program names. You must specify the
complete paths if the files are not saved in the directory of the
pallet table.
DATUM
: This entry is only required if datum tables are used. You
must specify the complete paths if the files are not saved in the
directory of the pallet table. You activate datums from the datum
tables in the NC program using Cycle 7.
PRESET
: This entry is only required if different reference points
are used. Enter the required preset numbers.
LOCATION
: Entry is obligatory. The entry "
MA
" indicates that the
machine is loaded with a pallet or fixture that can be machined.
The TNC only machines pallets or fixtures identified by "
MA
".
Press the
ENT
key to enter
MA
. Press the
NO ENT
key to
remove the entry.
LOCK
: This entry is optional. Using an
*
you can exclude the
row of the pallet table from processing. Press the
ENT
key
to identify the row with the entry
*
. Press the
NO ENT
key
to cancel the lock. You can lock the execution for individual
programs, fixtures or entire pallets. Unlocked lines (e.g. PGM) in
a locked pallet are also not executed.
