F2: Multi-axis transformations
3.2 5-axis transformation
MD24100 $MC_TRAFO_TYPE_<x> = <transformation type>
where x = 1, 2, ... maximum number of transformations
Axis se‐
quence of the
machine
Not a practical combination, as a rotation of the C axis would only correspond to a rotation of the tool
1)
around its own longitudinal axis (symmetrical axis).
Identifying the axis sequence
The axis sequence is identified in the following way:
● AB means: A is 4th axis, B is 5th axis of the 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.
Axis assignment
In the machine data, the axis assignment at the input of the 5-axis transformation defines which
axis will be mapped by the transformation to which channel axis:
MD24110 $MC_TRAFO_AXES_IN_<x> (axis assignment for transformation x)
where x = 1, 2, ... maximum number of transformations
