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.
Application example:
Retracting the spindle after tool breakage
8 Interrupt machining.
8 Enable the external direction keys: Press the MANUAL TRAVERSE
soft key.
8 Move the axes with the machine axis direction buttons.
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 buttons, the electronic
handwheel and the positioning logic for returning to the
contour are then 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.
On some machines you may have to press the machine
START button after the MANUAL OPERATION soft key to
enable the axis direction buttons. Refer to your machine
manual.
Your machine tool builder can define whether in a program
interruption you always move the axes in the currently
active (tilted or non-tilted) coordinate system. Refer to
your machine manual.
