Abstract
A method of efficiently forming a finished part, the method includes providing a cutting tool having a first cutting edge extending from a first end of the cutting tool, a second cutting edge extending from a second end of the cutting tool, and a shaping edge disposed between the first cutting edge and the second cutting edge. The cutting tool is advanced into a rotating workpiece such that the first cutting edge removes a trailing end of the rotating workpiece, the shaping edge shapes a working portion of the rotating workpiece, and the second cutting edge removes the working portion of the rotating workpiece to form the finished part.

A method of efficiently forming a finished part, the method comprising:
- providing a cutting tool having a longitudinal axis and a solid leading end, the solid leading end including:
- a first cutting edge extending from a first end of the cutting tool in a direction parallel to the longitudinal axis,
- a second cutting edge extending from a second end of the cutting tool, and
- a curved shaping edge disposed between the first cutting edge and the second cutting edge, the curved shaping edge being a concave curve having a center of curvature wherein a distal end of the first cutting edge is positioned a greater distance from the center of curvature than the second cutting edge;
- providing a rotating workpiece, the rotating workpiece including a trailing end, a leading end, and a working portion disposed between the trailing end and the leading end;
- and
- advancing the solid leading end of the cutting tool into the rotating workpiece along a plane that is parallel to the longitudinal axis of the cutting tool such that the first cutting edge removes the trailing end of the rotating workpiece, the curved shaping edge shapes the working portion of the rotating workpiece, and the second cutting edge removes the working portion of the rotating workpiece to form the finished part, the finished part being one of a sphere and an oval.
A method of efficiently forming a finished part, the method comprising:
- providing a cutting tool having a longitudinal axis and a solid leading end, the solid leading end including:
- a first cutting edge having a first sub-edge, the first sub-edge including a proximal end and a distal end, the distal end extending from the proximal end in a direction parallel to the longitudinal axis of the cutting tool,
- a second cutting edge having a distal end, the proximal end of the first sub-edge and the distal end of the second cutting edge being disposed together on a plane that is substantially perpendicular to the longitudinal axis such that the distal end of the first sub-edge extends from the plane, and
- a curved shaping edge extending from the proximal end of the first sub-edge to the distal end of the second cutting edge, the curved shaping edge being a concave curve;
- providing a rotating workpiece having a central axis, a trailing end, a leading end, and a working portion disposed between the trailing end and the leading end;
- and
- advancing the solid leading end of the cutting tool into the rotating workpiece along a plane that is parallel to the longitudinal axis of the cutting tool such that the first cutting edge removes the trailing end of the rotating workpiece when the distal end of the first sub-edge reaches the central axis of the rotating workpiece, the shaping edge shapes the working portion of the rotating workpiece, and the second cutting edge removes the working portion of the rotating workpiece to form the finished part when the distal end of the second cutting edge reaches the central axis of the rotating workpiece, the finished part being one of a sphere and an oval.
