Moving the machine axes during an interruption
You can move the machine axes during an interruption in the same
way as in the Manual operation mode.
Danger of collision!
If you interrupt program run while the working plane
is tilted, you can switch the coordinate system
between tilted and non-tilted, as well as to the active
tool axis direction, by pressing the 3-D ROT soft key.
The functions of the axis direction keys, the
electronic handwheel and the positioning logic for
returning to the contour are evaluated by the TNC.
When retracting the tool, make sure the correct
coordinate system is active and the angular values
of the tilt axes are entered in the 3-D ROT menu, if
necessary.
Example:
Retracting the spindle after tool breakage
Interrupt machining
Enable the axis direction keys: Press the MANUAL TRAVERSE
soft key
Move the machine axes with the axis direction keys
On some machines, after pressing the MANUAL
TRAVERSE soft key you may have to press the NC
START key to enable the axis direction keys. Refer to
your machine manual.
