            | Ring Cross Sections, Showing
            Draft and Machining Stock Requirements 
 |  | The circumference of
        the ring is a good candidate for reduced machining. 
          In the original design extra stock was required on the
            circumference because of the draft requirements of the forging dies. 
Using metal casting in sand molds, less draft is
            required on the circumference, so there is less stock to remove in the machining
            operation.  Go Back and Choose another
        Machining Feature (Outer or Inner Tab Faces) Or
