WARNING:
During tapping cycle, adjust the feed ban override and spindle override, prohibit the use of feed hold button.
NOTE:
1.
The tool radius compensation: When using a fixed cycle command, the tool radius compensation is
ignored.
2.
Cancel canned cycle: You can not use the G74 and 01 group G code in the same block, or G74 is
canceled.
3.
Cycle parameters: After the execution of a complete drilling cycles, the next block specified
individually when a new cycle parameters (Z, R, P), a new cycle parameters could not be effective; specify hole
data and when the follow-up procedure the new loop parameters (Z, R, P), a new cycle parameters take effect
immediately, and the modal in the following blocks.
Programming Example:
Thread lead 1.0mm
Feed per minute mode:
G0 G90 G54 X50. Y160. Z30.
Fast positioning to the hole 1
G94
Specify the feed per revolution mode
M29 S200
Specify rigid tapping mode
G98 G74 X50. Y160. Z-10. F200.
R3.
Executive tapping cycle and tapping a hole first, then
return to the initial plane
X-50.
Boring the holes 2, then return to the initial plane
Y-160.
Boring the holes 3, then return to the initial plane
X50.
Boring the holes 4, then return to the initial plane
G80
Fixed cycle canceled.

13.4.4 Rigid tapping cycle (G84)
In the rigid tapping mode, the spindle motor works like a servo motor, can achieve high speed and precision
tapping.
