7.4.1 Preconditions for TRAANG (inclined axis)
Axis configuration
To be able to program in the Cartesian coordinate system (see figure "Machine with inclined
infeed axis": X, Y, Z), it is necessary to inform the control of the correlation between this
coordinate system and the actually existing machine axes (MU,MZ):
● Assignment of names to geometry axes
● Assignment of geometry axes to channel axes
● Assignment of channel axes to machine axis numbers
● Identification of spindles
● Allocation of machine axis names.
With the exception of "Inclined axis active", the procedure is the same as for the normal axis
configuration.

Number of transformations
Up to 10 transformation data blocks can be defined for each channel in the system. The
machine data names of these transformations begin with $MC_TRAFO .. and end with ... _n,
where n stands for a number between 1 and 10. The following sections include descriptions
of these data:
MD24120 $MC_TRAFO_GEOAX_ASSIGN_TAB_n
MD24100 $MC_TRAFO_TYPE_n
MD24110 $MC_TRAFO_AXES_IN_n
Number of inclined axes
Two of the 10 permitted data structures for transformations may be assigned to the inclined
axis function. They are characterized by the fact that the value assigned to MD24100
$MC_TRAFO_TYPE_n is 1024.
