The online tool length offset function is an option and is available during "generic 5-axis
transformation" by default and for "orientable toolholders".
If the tool is not perpendicular to the workpiece surface during machining or the contour
contains curvatures whose radius is smaller than the compensation dimension, deviations
compared to the actual offset surface are produced. It is not possible to produce exact offset
surfaces with one tool length compensation alone.
