3.28.9 Boring Cycle (G85)
This cycle is used to bore a hole.
Format: G85 X_ Y_ Z_ R_ F_ L_ ;
X_ Y_: 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 feedrate
L_ : Number of repeats
G85 (G98) G85 (G99)
After positioning along the X and Y axis, rapid traverse is performed to point R. Drilling is
performed from point R to point Z. When point Z has been reached, cutting feed is performed to
return to point R.
Before specifying G85, use miscellaneous function (M code) to rotate the spindle. When the
G85 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 boring 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.
Note: 1. Before the drilling axis can be changed, the canned cycle must be canceled.
2. Do not specify a G code of the 01 group(G00-G03) and G85 in a single block.Otherwise, G85 will be
canceled and alarm.
Example : M3 S100 ; Cause the spindle to start rotating
G90 G99 G85 X300. Y-250. Z-150. R-120. F120.
Position, drill hole 1, then return to point R
Y-550 ; Position, drill hole 2, then return to point R
Y-750; Position, drill hole 3, then return to point R
X1000 ; Position, drill hole 4, then return to point R
G98 Y-750 ; Position, drill hole 5, then return to initial level
G80 ; Cancel canned cycle
M05 ; Cause the spindle to stop rotating.
