3-D compensation without tool orientation

The TNC displaces the tool in the direction of the surface-normal
vectors by the sum of the delta values (tool table and TOOL CALL).

Example: Block format with surface-normal vectors

The feed rate F and miscellaneous function M can be entered and
changed in the Programming and Editing mode of operation.

The coordinates of the straight-line end point and the components of
the surface-normal vectors are to be defined by the CAD system.
