Note
Order of the orientation axes
If you run through the kinematic chain that describes the structure of the machine, from the
workpiece to the tool, then the following specifications apply for the order of the three
orientation axes of a 6-axis transformation:
● The orientation axis that is closest to the workpiece is the first orientation axis.
● The orientation axis that is closest to the tool is the third orientation axis.
Generally, the first orientation axis is a spindle and the corresponding rotation is therefore
implemented in these cases through a rotating frame.
