The valid tool types for non-axially symmetrical tools and the maximum number of cutting
edges (Dn = D1 to D12) are defined by the machine manufacturer via machine data. Please
contact the machine manufacturer if not all of the 12 cutting edges are available.

Tool radius compensation, CUT2D
As for many applications, tool length compensation and tool radius compensation are
calculated in the fixed working plane specified with G17 to G19.
Example of G17 (X/Y plane):
Tool radius compensation is active in the non-rotated X/Y plane, tool length compensation in
the Z direction.
Tool offset values
For machining on inclined surfaces, the tool compensation values have to be defined
accordingly, or be calculated using the functions for "Tool length compensation for orientable
tools". For more information on this calculation method, see chapter "Tool orientation and
tool length compensation".
