Machining Speeds Feeds: milling_face
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)
| operation | record id | cutting speed sfm max (sfm) | cutting speed sfm min (sfm) | cutting speed sfm typical (sfm) | feed ipr max (in/rev) | feed ipr min (in/rev) | feed ipr typical (in/rev) | material | material group | notes | specific cutting energy hp per in3 per min (hp/(in3/min)) | surface finish Ra uin typical (uin) | tool type |
