Tool change

Tool change position
The tool change position must be approachable without collision. Use

the miscellaneous functions M91 and M92 to enter machine-based

(rather than workpiece-based) 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:

Move to the tool change position under program control

Interrupt program run (see "Interrupting machining", page 651)

Tool change

Resume program run (see "Resuming program run after an

interruption", page 654)

Automatic tool change
If your machine tool has automatic tool changing capability, the

program run is not interrupted. When the TNC reaches a TOOL CALL it

replaces the inserted tool by another from the tool magazine.

The tool change function can vary depending on the

individual machine tool. The machine manual provides

further information.
