Center of curvature as reference and normal position
Programming:
 Pattern center <> center of curvature
 Pattern radius = curvature radius
 Normal position
These commands arrange the slots at the distance of the pattern
radius plus curvature radius about the pattern center.
Example: Center of curvature as reference, normal position
Center of curvature as reference and original position
Programming:
 Pattern center <> center of curvature
 Pattern radius = curvature radius
 Original position
These commands arrange the slots at the distance of the pattern
radius plus curvature radius about the pattern center while keeping the
starting and ending angle.
