Pallet Management | 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
W-STATUS
The machining status defines the machining
progress. Enter BLANK for an unmachined
(raw) workpiece. The control changes this entry
automatically during machining.
The control differentiates between the following
entries
BLANK: 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
METHOD
Indicates the machining 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)
CTID
The control automatically generates the ID
number for mid-program startup with block scan.
If you delete or change the entry, mid-program
startup is no longer possible.
SP-X, SP-Y,
The entry for the clearance height in the existing
SP-Z, SP-A,
axes is optional.
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.
