When the single block function is active, the control stops axis motion
after steps 1, 2 and 6.
If the operator activates a feedhold during steps 3, 4 or 5, axis motion
stops after step 7. Axis motion will also stop during steps 1, 2, and 7.
However, if the operator activates a feedhold during step 7, axis motion
will stop immediately.
Important: Your system installer can enable a tap retract feature for this
cycle through PAL. Tap retract enables you to retract the tapping tool and
resume the cycle, or completely a bort the tapping operation. Refer to your
system installers documentation for details.
Use this c ycle to cut right-handed threads.
The format for the G84.1 cycle is:
G84.1X__Z__R__F__L__Q__D__S__;

Important: When programming and executing a G84.1 solid tapping
cycle, remember:
the feedrate of the tapping phases is derived as
(spindle {RPM}
