Cutting Time for Facing | Cutting Tool Engineering

A sample calculation using the same workpiece diameter, feed rate and rpm instead of the cutting speed is shown in Table 3. Comparison between the two methods of facing shows that machining at a constant sfm (0.98 minutes) requires significantly less time than machining at a constant rpm (1.90 minutes).

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.
