Example of a generic 6-axis transformation

Activation of a 6-axis transformation with subsequent orientation changes and traversing:
N10
N20
N30
N40
N50
A tool, of which the orientation differs from the default, is defined in the following example.
With G17, the orientation vector is in the X-Z plane and its inclination to the Z axis is 26.565
degrees because of tan(26.565) = 0.5 = $TC_DPV3[2,2] / $TC_DPV5[2,2].
The orientation normal vector is also specified. As only $TC_DPVN4[2,2] is not equal to zero,
it points in the Y direction. Orientation vector and orientation normal vector are perpendicular
to one another.
