The cycle executes the deep hole rigid tapping operation.
Command format: G84 X (U)_ C (H)_ Z (W)_ R_ Q_ P_ F_ K_ M_ ; or
G88 Z (W)_ C (H)_ X (U)_ R_ Q_ P_ F_ K_ M_ ;
Execution processing:
(1)The tool rapidly traverses to the hole
bottom position from the start point (i.e., the start point confirmed by the hole position data in the initial
plane)
；
(2)Rapidly position to point R;
(3)The spindle starts to rotate;
(4)The tapping axis feeds the cutting amount q specified by the cutting feedrate F; after the feed ends,
the spindle stops rotation;
(5)The spindle rotates reversely, and after the tapping axis executes the tool retraction to point R
plane, the spindle stops rotation
(6)The spindle starts rotation; the tapping axis executes the tool infeed to the distance d (the
retraction amount d of the deep-hole rigid tapping specified by No. 5213) away from the previous
machining plane;
