CAUTION: If the Jog Retract function is deactivated during its
execution (performing a control reset, E-STOP, etc.), attempting
to return the tool by pressing cycle start may cause the Jog
Retract funtion to abort. The tool will return to the start point of
jog retract along a linear path. This is most likely not the
retracted path. To avoid possible part or tool damage it is
recommended that the cutting tool be jogged to the point from
which jog retract was started prior to pressing
To perform a jog retract operation:
1.
Press the
button to stop program execution.
2.
Press the
on to indicate that the function is active.
3.
Move the cutting tool from the workpiece using either continuous
jog, incremental jog, or HPG jog operations. (see chapter 4 for
jogging information.)
4.
Inspect and change the tool or tool offset as desired. Details on how
to do this are in chapter 3.
5.
After completing the desired inspection or tool change, press the
become active when the cycle start is requested. The tool returns to
the location where jog retract began, following the same path used
when you jogged the tool away from the work piece (+ or -- any new
tool offset values).
Cycle stop may be pressed during the tools automatic return to the
jog retract start position. When this is done the tool may be retracted
from this point using jog moves and the control will add these moves
to any remaining jog retract steps that have not yet been returned.
6.
Once the cutting tool is fully returned from a jog retract operation the
control will continue on in the part program unless in single block
mode. If in single block mode the control will go to the cycle stop
state when the return from jog retract is completed. Press
