CONTOUR LINES cycle with a rotary axis
Define the starting point in a linear axis and in a rotary axis. Define also
the order and direction of axis approach. If the starting point lies in the X
and C axes, then the touch probe oscillates in the X/C plane.
This method also works well for machines that have only two linear axes
(e.g. Z/X) and one rotary axis (e.g. C).

The direction of rotation defined behind ORDER is valid for all levels (lines). This ensures that the workpiece is then
machined consistently either in up-cut or in climb milling.
