Along the X-axis and Y-axis after positioning, rapid traverse to R point, from point to point Z R Tapping is
performed. When tapping is completed, the spindle stops and execution is suspended, then the spindle in the
positive direction of rotation and return to point R, the spindle is stopped, then quickly move to the initial position.
When tapping cycle is being executed, the feed rate and spindle speed override default is 100%, but the fallback
speed adjusted by parameter 0607.
In the feed per minute mode (G94), thread lead = feed rate ÷ spindle speed; in feed per rotation mode (G95),
the thread lead equals the feed rate.
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 G84 and 01 group G code in the same block, or G84 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
