Rotary axis
The rotary axis cannot be programmed as it is occupied by a geometry axis and thus cannot be programmed directly as
channel axis.
Meaning
TRANSMIT: Activates the first declared TRANSMIT function. This function is also designated as polar transformation.
TRAFOOF: Deactivates an active transformation.
OFFN: Offset contour normal: Distance of the face machining from the programmed reference contour.
Note
An active TRANSMIT transformation is likewise deactivated if one of the other transformations is activated in the relevant
channel (e.g. TRACYL).
