Configuration of a machine for 5-axis transformation

To ensure that the 5-axis transformation can convert the programmed values to axis motions,
certain information about the mechanical design of the machine is required; this information is
stored in machine data:
• Machine type
• Axis assignment
• Geometry information
• Assignment of direction of rotation
Machine type
The machine types have been designated above as types 1 to 3 and are stored in the
following machine data as a two-digit number:
MD24100 $MC_TRAFO_TYPE_1 (definition of channel transformation 1)
...
MD24480 $MC_TRAFO_TYPE_10 (definition of channel transformation 10)
The following table contains a list of machine types, which are suitable for 5-axis
transformation.

AB 16
AC x
BA 18
BC x
CA 20
CB 21
Combinations that are not meaningful, whose C-axis corresponds to a rotation of the tool about its
longitudinal axis (symmetry axis), are marked by x.
Identification of axis sequence
The axis sequence is identified in the following way:
• AB means: A is 4th axis, B is 5th axis of transformation
• For machine type 3, the swivel axis of the tool is the 4th axis of the transformation and the
rotary axis of the workpiece is the 5th axis of the transformation.
