General relationships of universal tool head

Function
To obtain optimum cutting conditions when machining surfaces with a three-dimensional
curve, it must be possible to vary the setting angle of the tool.
The machine design to achieve this is stored in the axis data.
5-axis transformation
Cardanic tool head
Three linear axes (X, Y, Z) and two orientation axes (C, A) define the setting angle and the
operating point of the tool here. One of the two orientation axes is created as an inclined
axis, in our example A' - in many cases, placed at 45°.
