Test Run and Program Run
16.5 Program run
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 the 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.
Modifying the reference point during an interruption
If you modify the active reference point during an interruption,
resuming the program run is only possible with GOTO or mid-
program startup at the interruption point.
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 you may have to press the NC
START key after the MANUAL TRAVERSE soft key to
enable the axis direction keys. Refer to your machine
manual.
