Current trends in high-speed machining

The focus of the majority of high-speed machining research has been directed toward improving metal removal rates. Tool materials capable of withstanding high cutting speeds have become available (silicon nitride for cast iron, solid carbide for aluminum, and superabrasives for hardened steels), and the focus of research has shifted to maximizing the cutting performance of the machine tool. Measurement of cutting performance, chatter avoidance, structural design, tool retention, and axis control have become important research topics. The purpose of this paper is to provide an overview of the state of the art. in high-speed machining and to provide our view of the emerging research areas.
