CAUTION
1 This function is not effective for leading edge offset.
2 With a command for a rotation axis only, this function
does not calculate a cutter compensation vector.
3 This function cannot be used in three-dimensional
coordinate conversion mode.
4 The cautions for the three-dimensional cutter
compensation function also apply to this function

The cutter compensation vector (VD) is calculated on the compensation plane
vertical to the tool direction.
The cutter compensation vector (VD) on the compensation plane is converted
to that in the original Cartesian coordinate system.
The resulting vector is the cutter compensation vector (VD).
