Tooling Tips for High-speed Machining

High-speed machining (HSM) shaves time off metal removal processes. Low speeds and feeds that remove a large amount of material are replaced with light depths of cuts made at high feed rates. Metal is removed quickly, and the resulting near-net-shape parts, with surface finishes often from 10 to 12 RMS, reduce the semi-finish and finish operations.
