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
