Detailed Description
2.1 Defining a geometry axis as transverse axis
Transverse axis
Within the framework of "turning" technology, the transverse axis refers to the machine axis
that travels perpendicular to the axis of symmetry of the spindle, in other words, to
longitudinal axis Z.

Definition
Definition of a transversing axis in the channel
The definition of a geometry axis as a transverse axis is done using machine data:
MD20100 $MC_DIAMETER_AX_DEF (geometry axis with transverse axis function ).
For this axis, diameter programming and assigning a constant cutting speed with
G96/G961/G962 are both permitted.
Definition of several transversing axes in the channel
The machine data MD30460 $MA_BASE_FUNCTION_MASK allows the definition of
additional transverse axes, for which axis-specific diameter programming with bit2=1 is
possible.
An axis can be simultaneously defined in MD20100 and in MD30460 with bit2. For this, the
channel-specific MD20100 has a higher priority than the axis-specific MD30460.
