G81 Drilling Cycle
Command Format:
G81 X_Y_Z_R_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)
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 increment mode)
Hole machining operation is as shown in Fig. 4-23. G81 is used for general drilling.
