SFM is a combination of diameter and the velocity of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 surface meter per second (meter per second, or m/s, is the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.
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 a chart titled, "Alloy Steels," not "low alloy steels." The chart lists the alloy steels from 1320 to 9262 with a range of 65 to 120 SFM. This chart has been used by many machinists throughout the years and is published by an authority: Brown & Sharpe. So as long at the chart is titled "Alloy Steels." I'm sticking with the reference.

A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
It is a common material used in competition yo-yos as well. Another application for the 7075-series alloy has been in connecting rods used in drag racing engines. Aluminum rods do not have the fatigue life of forged steel rods, but have less mass than their steel counterparts, resulting in lower mechanical stress during periods in which an ...
Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of
Characterization, when used in materials science, refers to the broad and general process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained.
