8.1 Pallet management (option number 22)
Application
Refer to your machine manual.
Pallet table management is a machine-dependent
function. The standard functional range is described
below.
Pallet tables (
.p
) are mainly used in machining centers with pallet
changers. The pallet tables call the different pallets (PAL), fixtures
(FIX) optionally, and the associated NC programs (PGM). The pallet
tables activate all defined presets and datum tables.
Without a pallet changer you can use pallet tables to process NC
programs with different presets in sequence with just one press of
NC Start
.
The file name of a pallet table must always begin with a
letter.
