Nc Macro For Changing The Tool During Tool-Oriented Machining - HEIDENHAIN TNC 426 PB/M Technical Manual

NC macro for
changing the tool
during tool-
oriented machining
December 2001
Module 9281 Selection of a line in the pallet table
With this module you set the cursor on a particular line of the pallet table that
you selected in the program run mode. Datum shift and datum setting can be
run immediately. If the TNC is in another mode, the selection will be made
when the control returns to the program run mode.
Call:
PS B/W/D/K <Line number in the pallet table>
PS B/W/D/K <Mode>
Bit 0 –
0: Do not run datum shift or set the datum
1: Run the datum shift/set the datum immediately
Bit 1 – Shift the datum/set the datum
0: Do not run if the line is disabled by an entry in the LOCK
column
1: Run even if the line is disabled by an entry in the LOCK
column
CM 9281
PL B/W/D <Error code>
0: No error. The line was selected.
1: Module was not called in a spawn job or submit job
2: Call during running program
3: No pallet table selected in full sequence
4: Line does not exist
5: Error during datum setting, in the datum table or pallet
table
A special tool-change macro is required for tool-oriented pallet machining. This
is defined through the keyword TCTOOLMODE= in NCMACRO.SYS.
This specific NC macro is called for tool oriented machining instead of the
standard tool-change macro. If this specific NC macro is not defined in
NCMACRO.SYS, a HEIDENHAIN standard macro is run.
The HEIDENHAIN standard macro performs the following functions:
n
Positioning to clearance height
n
Execution of M146
n
Tool change through TOOL CALL. The standard tool-change macro is called.
With FN18: Qxxx = ID510 NR5 or NR6 IDX<Axis>, you can find whether a
clearance height has been programmed for an axis, and if so, the value
specified for the clearance height in the NC macro.
With the M function M146 the current geometry information is saved in a
temporary file. This information is required for continuing NC program run after
an interruption due to a TOOL CALL during tool-oriented machining. In
addition, a code is entered in the CTID column and the entry in W-STATE is
changed to INCOMPLETE, if required.
