2.10.4 Interrupting a program
Retracting from a
contour
After you have interrupted a program ("NC Stop") in Automatic mode
(e.g. in order to take a measurement on the workpiece and correct the
tool wear values or after tool breakage), you can retract the tool from
the contour in "Machine Manual" mode. In such cases, ShopMill
stores the coordinates of the interruption point and displays the
differences in distance traveled by the axes in "Machine Manual"
mode as a "Repos" (= Reposition) offset in the actual value window.
For details of how to traverse machine axes, please refer to Sec.
"Traversing machine axes".
Repositioning
The "Repos" function repositions the tool on the workpiece contour
after traversal of the machine axes during a program interruption in
Automatic mode.
Jog
îš¾ Select "Machine Manual" mode.
Move the axes away from the point of interruption.
Repos
îš¾ Press the "Repos" key.
X
...
îš¾ Select the axis to be traversed.
+
îš¾ Press the "+" or "-" key.
It is not possible to overtravel the point of interruption.
The feedrate override is active.
Warning
The rapid traverse override switch is active.
Non-adjusted Repos offsets are adjusted with program advance and
linear interpolation on switchover to Automatic mode followed by start
with the "Cycle start" key.
