Generating spherical surfaces | Cutting Tool Engineering

 · The spherical surface generation technique can produce a full sphere. A single-point cutting tool sweeps through a circle that has no thickness on one side of the cutting edge. If you think about how a ring of any size smaller than the spherical surface can lay in full contact with the sphere, you can visualize how the cutting action takes place.
