G89 Boring Cycle of Dwell at the Bottom of Hole
Command Format: G89 X_Y_Z_R_P_F_K_;
Description:
X_Y_: hole position data (absolute/incremental coordinate)
Z_: the position of point Z at the bottom of the hole (absolute programming); the distance from
point R to point Z at the bottom of the hole (incremental programming)
R_: the position of point R (absolute programming); the distance from the initial point to point R
(incremental programming)
P_: the dwell time at the bottom of the hole, in ms, with no decimal point
F_: feed speed, even if the canned cycle is cancelled, this modal data is still effective in the
subsequent machining.
K_: number of repeats (repeated movement and drilling, effective under G91 incremental mode)

Process Description:
1. The cutter moves to the hole position (X, Y) in G00;
2. Moves down to the specified point R in G00;
3. Moves down to point Z at the bottom of the hole in G01;
4. Pauses for P;
5. Retracts to point R in G01;
6. Retracts to initial point (G98) or point R (G99) in G00.
