Pallets | Tool-oriented machining
Pallet table columns for tool-oriented machining
Unless the machine tool builder has made a different configuration,
you need the following additional columns for tool-oriented
machining:
Column Meaning
The machining status defines the machining
W-STATUS
progress. Enter BLANK for an unmachined
(raw) workpiece. The control changes this entry
automatically during machining.
The control differentiates between the following
entries
BLANK / no entry: Workpiece blank, requires
machining
INCOMPLETE: Partly machined, requires
further machining
ENDED: Machined completely, no further
machining required
EMPTY: Empty space, no machining required
SKIP: Skip machining
Indicates the machining method
METHOD
Tool-oriented machining is also possible with a
combination of pallet fixtures, but not for multiple
pallets.
The control differentiates between the following
entries
WPO: Workpiece oriented (standard)
TO: Tool oriented (first workpiece)
CTO: Tool oriented (further workpieces)
The control automatically generates the ID
CTID
number for mid-program startup with block scan.
If you delete or change the entry, mid-program
startup is no longer possible.
The entry for the clearance height in the existing
SP-X, SP-Y,
axes is optional.
SP-Z, SP-A,
SP-B, SP-C,
You can enter safety positions for the axes. The
SP-U, SP-V,
control only approaches these positions if the
SP-W
machine tool builder processes them in the NC
macros.
