The phrase speeds and feeds or feeds and speeds refers to two separate velocities in machine tool practice, cutting speed and feed rate. They are often considered as a pair because of their combined effect on the cutting process. Each, however, can also be considered and analyzed in its own right. Cutting speed (also … See more 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 … See more The spindle speed is the rotational frequency of the spindle of the machine, measured in revolutions per minute (RPM). The preferred speed is determined by working … See more Cutting speed and feed rate come together with depth of cut to determine the material removal rate, which is the volume of workpiece … See more Speeds and feeds have been studied scientifically since at least the 1890s. The work is typically done in engineering laboratories, with … See more Feed rate is the velocity at which the cutter is fed, that is, advanced against the workpiece. It is expressed in units of distance per … See more Speed-and-feed selection is analogous to other examples of applied science, such as meteorology or pharmacology, in that the theoretical modeling is necessary and useful but can … See more • Brown & Sharpe.
