Materials will run better at specific SFMs. The actual surface footage can vary according to the rigidity of the work holding and the runnout of the toolholder/cutting tool interface. When the SFM constant is known for a specific material, the formulas below can be used to determine spindle speed for milling various materials.
Once the SFM for a given material and tool is determined, the spindle can be calculated since this value is dependent on cutting speed and tool diameter. RPM = (CS x 4) / D Where: RPM = Revolutions per minute. CS = Cutter speed in SFM. D = Tool Diameter in inches. Milling Feed
The woven fabric portion of the textile industry grew out of the industrial revolution in the 18th century as mass production of yarn and cloth became a mainstream industry. In 1734 in Bury, Lancashire John Kay invented the flying shuttle — one of the first of a series of inventions associated with the cotton woven fabric industry.

As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.
STI (Specialty Textiles, Inc.), the makers of Revolution, first introduced Revolution to the furniture industry in March 2014.

Carbon Impacts of Steel . Steel is manufactured in two types of factories. Large steel mills typically use basic oxygen furnaces (BOFs), which burns coal or natural gas to melt iron-ore to extract the iron, and then mixes the iron with scraps of iron and steel to make new steel. Most of the inputs to a BOF are mined, raw materials, so the recycled content level for BOFs is …
where i is an input (kg, J, or W·h) of a mill, EFi is the respective input's emission factor (kg CO 2 eq per input unit), and P is the total annual product production (metric tons / year). If the input is a fuel, the emission factor includes both on-site and embodied GHG emissions.
