G86 X_ Z_ R_ F_ ;
X_ : Hole position data
Z_ : The distance from point R to the bottom of the hole
R_ : The distance from the initial level to point R level
F_ : Cutting feed rate
: Number of repeats
Point R

Spindle stop
Spindle CW
After positioning along the X–axis, rapid traverse is performed to point
R.
Drilling is performed from point R to point Z.
When the spindle is stopped at the bottom of the hole, the tool is retracted
in rapid traverse.
Before specifying G86, use a miscellaneous function (M code) to rotate
the spindle.
When the G86 command and an M code are specified in the same block,
the M code is executed at the time of the first positioning operation.
The system then proceeds to the next drilling operation.
When a tool length offset (G43, G44, or G49) is specified in the canned
cycle, the offset is applied at the time of positioning to point R.
