High removal rate (HRR) machining involves the use of extremely rigid, high-power, high-precision machines, such as roll turning lathes, to achieve material removal rates far beyond the capacity of conventional machine tools. This article reviews the machine requirements and cutting parameters of HRR machining. Machine components such as the lathe bed, tailstock, headstock, carriage, and tooling are detailed. The article also discusses the applications of HRR machining.
