1) Direction of imaginary (In case of right hand coordinate)
Direction of imaginary seen from the center of radius is decided by the cutting direction of tool
during the cutting. Therefor, it should be set as much as compensation volume.
Direction and number of imaginary are decided among the following eight
types.
