The tapping cycle (G84) and left–handed tapping cycle (G74) may be
performed in standard mode or rigid tapping mode.
In standard mode, the spindle is rotated and stopped along with a
movement along the tapping axis using miscellaneous functions M03
(rotating the spindle clockwise), M04 (rotating the spindle
counterclockwise), and M05 (stopping the spindle) to perform tapping.In
rigid mode, tapping is performed by controlling the spindle motor as if
it were a servo motor and by interpolating between the tapping axis and
spindle.
When tapping is performed in rigid mode, the spindle rotates one turn
every time a certain feed (thread lead) which takes place along the tapping
axis. This operation does not vary even during acceleration or
deceleration.
Rigid mode eliminates the need to use a floating tap required in the
standard tapping mode, thus allowing faster and more precise tapping.
When the spindle motor is controlled in rigid mode as if it were a servo
motor, a tapping cycle can be sped up.
