- M code used for C-axis clamp/unclamp
T
When an M code specified in parameter No.5110 for C-axis
clamp/unclamp is programmed, the CNC issues the M code for C-axis
clamp after the tool is positioned and before the tool is fed in rapid
traverse to the point-R level. The CNC also issues the M code (M
code C-axis clamp +1) for C-axis unclamp after the tool retracts to the
point-R level. The tool dwells for the time specified in parameter No.
5111.
- Tapping signal
During a tapping cycle, the tapping signal is output. The tapping
signal is also output while the G code of the tapping cycle is valid.
- Override
During tapping, cutting feedrate override is always set to 100%.
- Feed hold
When the feed hold key is pressed during tapping, the movement is
not stopped immediately but the movement is stopped when the tool is
returned to level R.
- Dry run
The parameter TDR (No. 1401#5) specifies whether dry run is valid
during tapping.
(Note 1) When parameter M5T (No.
5105#3)=0, M05 is not output.
(Note 2) Another M code may be used by
parameter No. 5112 and 5113.
