11.7 G86 Cycle

The G86 cycle is intended for boring.

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. Retract the Z-axis at traverse rate to clear Z.

5. Restart the spindle in the direction it was going. This cycle is very similar to g82 except that it stops the spindle before it retracts the tool and restarts the spindle when it reaches the clearance value R.
