X_ Y_: Hole position data
Z_ :
The distance from point R to the bottom of the hole and the position of the bottom of the hole
R_ : The distance from the initial level to point R level
P_ : Dwell time at the bottom of the hole and at point R when return is made.
F_ : Cutting feedrate
L_ : Number of repeats (Only for necessity of repeat)

The rigid tapping mode cancel command is G80:. Rigid tapping cycle
mode is also canceled by issuing another canned cycle G code or group
01G code which cancels a tapping cycle. In addition, rigid tapping
mode is canceled by the input of a reset (by pressing the reset button or
by making an external reset).
The only difference between the rigid tapping cycle and the reverse
rigid tapping cycle (G84.2) is the direction of spindle rotation.
CAUTION
During cutting feed along the Z-axis, the feedrate
override is assumed to be 100%. However, the
extraction speed (operation 5) can be overridden by
1% to 200% depending on the setting made for
parameter No. 5883.
