4. Inspect and change the wheel or wheel offset as desired. Details on
how to do this are on page 3-4.
5. After completing the desired inspection, dressing, or wheel change,
press the
<CYCLE START> button. Any wheel offset changes you have
made become active when the cycle start is requested. The wheel
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 offset values).
You can press
<CYCLE STOP> during the wheel automatic return to
the jog retract start position. When this is done, the wheel can be
retracted from this point using jog moves and the control adds these
moves to any remaining jog retract steps that have not yet been
returned.
6. Once the grinding wheel is fully returned from a jog retract operation,
the control continues on in the part program unless i n single block
mode. If in single block mode, the control goes to the cycle stop state
when the return from jog retract is completed. Press
<CYCLE START>
again to resume program execution.
