Machining Speeds Feeds: turning roughing
stainless 304#coated carbide to titanium Ti6Al4V#coated carbide
Machining speeds and feeds reference data — cutting speed (SFM), feed rate (IPR/IPT), depth of cut, tool life, surface finish, and specific cutting energy for 9 operations (turning roughing/finishing, milling face/end/slot, drilling, reaming, tapping, boring) across 14 workpiece materials (low/medium/high carbon steel, alloy steel, stainless 304/316, gray and ductile cast iron, aluminum 6061/7075, brass, copper, titanium Ti-6Al-4V, Inconel 718, plastics) and 6 tool types (HSS, uncoated carbide, coated carbide TiAlN, ceramic, CBN, PCD)
