The orientation is pivoted through 90 degrees on the XZ plane from -45 to +45 degrees. Due
to the smoothing of the orientation characteristic the orientation is no longer able to reach the
maximum angle values of -45 or +45 degrees.

Orientation relative to the path

Functionality
Irrespective of certain technological applications, the previous programming of tool orientation
is improved in that the programmed relative orientation in relation to the total path is maintained.
The required deviations from the ideal orientation path can be specified if, for example, a corner
occurs in the contour.
Tool orientation can be modified not only via configurable machine data, but also via new
language commands in the part program. In this way, it is possible to maintain the relative
