SECTION 7 FIXED CYCLES
This M code is cleared by the reset operation and it is effective only in the specified block.
An M code is given priority over the optional parameter setting.
When no M code is designated, the optional parameter setting becomes effective.
•
The basic axis motions of the tapping cycle (G184), synchronized tapping cycle (G178/G179),
and milling/boring cycle (G189) are shown below when the setting for the optional parameter
indicated above is "1" or if an M136 command exists in the program.
