Abstract:
An apparatus for cutting rings from ring forgings of either of titanium and related materials, comprising:means for removably holding and rotating said ring forging about a longitudinal axis, said axis extending through a centerline of the ring forging; means for rotating said ring forging at at least one speed and in at least one direction; a tool holder adjustably mounted spaced from and parallel to said axis; means for controlling a displacement of the tool holder from the means for holding the ring forging along said axis, thereby allowing an operator to determine a thickness of a ring to be cut from the ring forging; means for controlling a displacement of the tool holder from said axis to affect cutting of the ring from the ring forging; first and second cutter bars, said first and second cutter bars being removably mounted to said tool holder such that said cutter bars are positioned orthogonally with respect to said axis; said first cutter bar including a first cutting bit, said first cutting bit having a first cutting edge of a first predetermined width, said first cutting edge being positioned to move along a diameter of the ring forging toward said axis; said second cutter bar including a second cutting bit, said second cutting bit having a second cutting edge of a second predetermined width, said second predetermined width being wider than said first predetermined width, said second cutting edge being positioned to move along a line parallel to and spaced from said diameter, said line being coplanar with said diameter; and said second cutting bit being disposed to engage said ring forging after said first cutting bit engages said ring forging as said first cutting edge is moved along said diameter.
