The G88 cycle is intended for boring. This cycle uses a P value, where P specifies the number of seconds to dwell.
0. Preliminary motion, as described above.
1. Move the Z-axis only at the current feed rate to the Z position.
2. Dwell for the given number of seconds.
3. Stop the spindle turning.
4. Stop the program so the operator can retract the spindle manually.
5. Restart the spindle in the direction it was going. It is unclear how the operator is to manually move the tool because a change to manual mode resets the program to the top. We will attempt to clarify that step in this procedure.
