Among the full range of options specified in the general concept above, the settings
highlighted in gray in the following table are implemented in SW 3.1, the others in SW 3.2
and higher.
Implementation
The table below gives the values for $MC_TRAFO_TYPE_n for the configurable axis
sequences and for the orientation direction of the tool in position zero, showing separate
data for movable tool, movable workpiece and movable tool and workpiece. The
transformation does not support any table elements which do not contain a preset value.

Example of transformation type
$MC_TRAFO_TYPE = 148 for example, means:
The first rotary axis is parallel to the Z axis,
the second rotary axis is an inclined X axis and tool orientation in zero position points in the
Z direction.
Only the tool is moved by both rotary axes.
Bit 8 = 1: Universal milling head
Bit 6 and 7 = 00: Movable tool
Bits 5 and 4 = 10: Orientation in zero position in the Z direction
Bit 3 -1 = 100: Axis sequence CA'
