3.28.12 Boring Cycle (G89)
This cycle is used to bore a hole.
Format: G89 X_ Y_ Z_ R_ P_ 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
P_ : Dwell time at the bottom of a hole
F_ : Cutting feedrate
L_ : Number of repeats
G86 (G98) G86 (G99)
This cycle is almost same to G85. The difference is that this cycle performs a dwell at the
bottom of the hole.
Before specifying G89, use miscellaneous function (M code) to rotate the spindle. When the
G89 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 G86 in a single block.Otherwise, G86 will be
canceled and alarm.
Example : M3 S100 ; Cause the spindle to start rotating
G90 G99 G89 X300. Y-250. Z-150. R-120. P1 F120. ;
Position, drill hole 1, then return to point R
Then stop at the bottom of the hole for 1s.
Y-550 ; Position, drill hole 2, then return to point R
X1000 ; Position, drill hole 3, then return to point R.
G98 Y-750 ; Position, drill hole 5, then return to initial level.
G80 G28 G91 X0 Y0 Z0 ; Return to the reference position
M05 ; Cause the spindle to stop rotating.
