Tool change
Tool change position
The tool change position must be approachable without collision. With
the miscellaneous functions M91 and M92, you can enter machine-
referenced (rather than workpiece-referenced) coordinates for the tool
change position. If TOOL CALL 0 is programmed before the first tool
call, the TNC moves the tool spindle in the tool axis to a position that
is independent of the tool length.
Manual tool change
To change the tool manually, stop the spindle and move the tool to the
tool change position:
8 Move to the tool change position under program control.
8 Interrupt program run (see “Interrupting machining” on page 562).
8 Change the tool.
8 Resume program run (see “Resuming program run after an
interruption” on page 564).
The tool change function can vary depending on the
individual machine tool. The machine tool manual
provides further information.
