G84
* * Tapping canned cycle.
G84 [Z] I [K] R [J] B H
Z: Reference plane
I: Tap depth
K: Dwell in seconds at the bottom of the hole
(default =0)
R: Type of threading
R0: Normal tapping (only for spindles that
don’t have the spindle positioning option).
R1: Rigid tapping
J: Withdrawal feedrate factor. When rigid
tapping, the returning feedrate will be J times
the tapping feedrate. When not programmed
or programmed J1, they will both be the same
B: Penetration step when tapping with chip
removal (only for R1)
H: Withdrawal distance after each penetration
step (only for R1)
Note: If G94 (F in mm/min) it is programmed
with F and S. For S, the value of F will be:
F (mm/min) = S (rpm) * Pitch (mm/rev)
