Drilling cycle G88 <W5DBore8>
Drilling cycle type <W5DBore8(488)> (G88) drills holes with rapid approach to the safe level, dwell at hole bottom level, spindle stop and manual retract to the safe plane level.
Drilling cycle G88 consist of the following steps:
Rapid tool motion to the hole center at the <Z return> level.
Rapid descend to the <Z safe> level.
Work feedrate motion to the <Z min> level.
<Dwell> at the <Z min> level.
<Spindle stop>.
Manual tool retract to the <Z return> level.
Restore the spindle rotation direction and speed.
