1. G Function Description
1.2.39 G84: TAPPING DRILLING CYCLE
Command form:
G84 X Y Z R P Q F K ；
X_ or Y_: hole position data (absolute/increment mode)
Z_:
G91: the distance from the bottom of the hole to point Z (directional)
G90: program position of point Z
R_:
G91: the distance from initial level to R point level (directional)
G90: program position of point R
P_: dwell time at the bottom of the hole(s)
Q_: the feed depth (increment and positive value; negative value is
neglected)
F_: feed rate
K_: number of repeats (repeat moving and drilling, G91 is effective)
X, Y, Z, R is absolute or increment mode, decided by G90/G91.
PIC:
Type I: None argument Q
