(7)The tapping axis executes the cutting feed to the distance q+d
；
(8)Repeat the above Step 5, 6, 7 till the tool reaches the hole bottom plane; the spindle stops rotation
(9)The system dwells the time specified by P
；
(10)The spindle rotates oppositely, and the tapping axis returns to point R plane at the special speed;
(11)Rapidly return to the initial plane
；
(12)The high-speed deep-hole rigid tapping cycle ends.

Note 1
：
In the rigid tapping cycle, the tool retraction speed and the cut-in previous machining plane’s
speed are confirmed by the feedrate F (for the tapping axis, the federate is the specified F, used to
differentiate G98 and G99
；
for the spindle, the feedrate is to specify the spindle speed) and the
drawing override.
When DOV(NO.5200#4 ， the tool retraction is valid or not when the rigid tapping is performed) is set
to 0, the drawing override is fixed to 100%.
When DOV(NO.5200#4) is set to 1 ， it is divided into two conditions:
（ 1 ） When OV3 （ NO.5201#4 ， the address J specifies the spindle speed is valid or not during the tool
retraction, which can confirm the drawing override ） . lt is set to 0 ， the drawing override is set by
NO.5211
（
override value during the rigid tapping drawing
，
thereinto
，
OVU(NO.5201#3)
It is used to set the setting unit of rigid tapping’s drawing override parameter. i.e., NO.5211 unit is 1%
or 10%
。
