This cycle performs peck drilling.
It performs intermittent cutting feed to the bottom of a hole while
removing shavings from the hole.
G83
G83 X_ Z_ R_ Q_ 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
Q_ : Depth of cut for each cutting feed
F_ : Cutting feedrate

Point Z
Q represents the depth of cut for each cutting feed. It must always be
specified as an incremental value.
In the second and subsequent cutting feeds, rapid traverse is performed
up to a point just before d mm (or inch) where the last drilling ended, and
cutting feed is performed again.
Be sure to specify a positive value in Q. Negative values are ignored.
d is set by parameter No.5115 (CYCD).
Before specifying G83, use a miscellaneous function (M code) to rotate
the spindle.
When the G83 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.
