When the G84 and M code are specified in the same block, the positioning operation is performed while the
M code, and then the next tapping action. When specifying the number of repetitions K, M code is executed only
at the first hole, after, no M code is executed.
When the tool length compensation in a fixed cycle block (G43, G44, G49) , positioning to point R bias.
P for the hole bottom dwell time, in milliseconds, can only be a multiple of 100.
Before using G84 tapping cycle, the spindle must be specified by M codes.
Fig. 13-14
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 G83 and 01 group G code in the same block, or G81 is
canceled.
3.
Cycle parameters: When executed after a complete drilling cycles, the next block to specify a new loop
parameters alone (Z, R, P), a new cycle parameters could not be effective; specify hole data and when the
follow-up procedure when a new cycle parameters (Z, R, P), a new cycle parameters take effect immediately, and
the modal in the following blocks.
Program Example:
G0 G90 G54 X50. Y160. Z30. S100

；
Fast positioning to the hole 1 , the spindle is
rotated.
G98 G84 X50. Y160. Z-10. F100. R3.

；
Executive tapping cycle and tapping a hole first,
then return to the initial level and pause one second at
the hole bottom.
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.
