Command Format:
G84 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 still effective in the
subsequent machining.
(Currently, tapping speed is set by the parameter ―Spindle Speed When
Tapping‖, instead of by this F data.)
K_: number of repeats (repeated movement and drilling, effective under G91 incremental mode)
