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 parts program. In this way, it is possible to maintain the relative
orientation not only at the block end, but also throughout the entire trajectory. The desired
orientation is achieved:
• By settable orientation methods with ORIPATH, specifying how interpolation is to be
performed relative to the path.
• Whether the tool orientation should either always run continuously with specifiable
deviations from the orientation relative to the path at a block transition, or whether the
