Centrifugal compressor - Wikipedia

Centrifugal compressors, sometimes called radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.. They achieve a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or impeller.This kinetic energy is then converted to an increase in potential energy/static pressure by slowing the flow through a diffuser.

Speeds and feeds - Wikipedia

Cutting speed. Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
