3.28.7 Peck Drilling Cycle (G83)
This cycle performs peck drilling. It performs intermittent cutting feed to the bottom of a
hole while removing shavings from the hole.
Format: G83 X_ Y_ Z_ R_ Q_ F_ L_ ;
X_ Y_ : Hole position data
Z_ : The distance from point R to the bottom of the hole
R_ : The distance from initial level to point R level
Q_ : Depth of cut for each cutting feed
F_ : Cutting speed
L_ : Number of repeats
G83 (G98) G83 (G99)
Q represents the depth of each cutting feed. It must be specified in an incremental value. In the
second and subsequent cutting feed, rapid traverse is performed up to a d point just before where the
last drilling ended, and cutting feed is performed again. d is set by P2 in User parameter.
Be sure to specify a positive value in Q. Negative values are ignored.
Before specifying G83, use 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 position to point R. In the canned cycle mode, tool offsets are ignored.
Example
: M3 S2000 ; Cause the spindle to start rotating.
G90 G99 G83 X300. Y-250. Z-150. R-100. Q15. F120. ;
Position, drill hole 1, then return to point R.
Y-550.; Position, drill hole 1, then return to point R.
G98 Y-750.; Position, drill hole 1, then return to the initial level.
G80; Cancel canned cycle
M05; Cause the spindle to stop rotating.
