12.6 Three-Dimensional Tool Compensation (Software Option 2)
NC Program
3D-ToolComp works only with programs that contain a surface normal
vector (see “Definition of a normalized vector” on page 488). The
following must be considered for NC program generation by means of
the CAM system:
 If the NC program is calculated with reference to the center of the
sphere, you must define the nominal radius value R2 of the radius
cutter in the tool table (TOOL.T)
 If the NC program is calculated with reference to the south pole of
the sphere, you must define the nominal radius value R2 of the
radius cutter and also the R2 value as a negative delta length in the
DL column of the tool table (TOOL.T)
Example: Three-axis program with surface normal vector
Example: Five-axis program with surface normal vector
