Surface feet per minute (SFPM or SFM) is the combination of a physical quantity (surface speed) and an imperial and American customary unit (feet per minute or FPM). It is defined as the number of linear feet that a location on a rotating component travels in one minute. Its most common use is in the measurement of cutting speed (surface 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.
It is known that B1112 has a tool life of 60 minutes at a cutting speed of 100 sfpm. If a material has a machinability rating of 70%, it can be determined, with the above knowns, that in order to maintain the same tool life (60 minutes) the cutting speed must be 70 sfpm (assuming the same tooling is used).

A burin diagram, showing the handle, shaft, cutting tip, and face. [1] The bend in the shaft is especially associated with wood engraving. [2] A burin (/ ˈ b j ʊər ɪ n, ˈ b ɜːr ɪ n / BUR(E)-in) is a steel cutting tool used in engraving, from the French burin (cold chisel). Its older English name and synonym is graver. [3]
The most important of the tools used in line-engraving is the burin, or graver, a bar of steel with one end fixed in a handle, somewhat resembling a mushroom with one side cut away. The burin is shaped so that the sharpened, cutting end takes the form of a lozenge , and points downward.
