3.28.8 Right-handed Peck Rigid Tapping Cycle (G84)
Tapping a deep hole in rigid tapping mode may be difficult due to chips sticking to the tool or
increased cutting resistance. In such cases, the peck rigid tapping cycle is useful.
This cycle may be performed in standard mode or rigid tapping mode.
In standard mode, the spindle is rotated and stopped along with a movement along the tapping
axis using miscellaneous functions M03 (Rotating the spindle clockwise), M04 (rotating the spindle
counterclockwise), and M05 (Stopping the spindle) to perform tapping following with SP-Encoder.
In Rigid tapping mode, tapping is performed by controlling the spindle motor as if it were a
servo motor and by interpolation between the tapping axis and spindle. When tapping is performed
in rigid mode, the spindle rotates one turn every time a certain feed(thread lead) which takes place
along the tapping axis. This operation doe not vary even during acceleration or deceleration.
In this cycle, cutting is performed several times until the bottom of the hole is reached.
Format: G84 X_ Y_ Z_ R_ P_ Q_ K_ L_ S_ ;
X_ Y_ : Hole position data
Z_ : The distance from point R to 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. Unit s.
Q_ : Depth of cut for each cutting feed
K_ : Pitch of Screw
S_ : Speed of Spindle
L_ : Number of repeats

After positioning along X and Y axis,rapid traverse is performed to point R. From point R,
cutting is performed with depth Q (depth of each cutting feed), then the tool is retracted by distance
