The milling process definitions cutting speedv c indicates the surface speed at which the cutting edge machines the workpiece effective or true cutting speed v e indicates the surface speed at the effective diameter (dc ap)this value is necessary for determining the true cutting data at the actual depth of cut (a p)this is a particularly important value when using round insert cutters .
Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth such as an end mill or face mill calculations use the desired tool diameter number of teeth cutting speed and cutting feed which should be chosen based on the specific cutting conditions including the workpiece material and tool material.
ef1 dry grinding for the same range of work dry grinding requires 13 times as much power as wet grinding ef2 open circuit grinding when grinding in open circuit ball mills the amount of extra power required compared to closed circuit ball milling is a function of the degree of control required on the product produced the inefficiency factors for open circuit .
Volumetric loading is similar to that of a ball mill (30-35%) design standards for drive components are more demanding than ball mills; dry applications feature a peripheral discharge or an air-swept arrangement; typical operating speeds are slower than either sag or ball mills: 65-70% tcs (wet) and 62-63% tcs (dry).
