what is the cutting speed for mild steel
Speeds and feeds 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 100Â 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. The cutting conditions will affect the value of this surface speed for mild steel.
Autobahn A 2008 estimate reported that 52% of the autobahn network had only the advisory speed limit, 15% had temporary speed limits due to weather or traffic conditions, and 33% had permanent speed limits.[2] Measurements from the German State of Brandenburg in 2006 showed average speeds of 142 km/h (88 mph) on a 6-lane section of autobahn in free-flowing conditions.[3]
