The Milling Process – Definitions Cutting speed,v 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 ...
Tap Feed Calculator Instructions This is used to calculate feed rates for rigid tapping in CNC Enter Threads per inch (not pitch, i.e. 32 or 20) Enter the spindle speed in revolutions per minute. Result will be the feed rate in inches per minute. CNC machines usually .

Unit 2: Speeds, Feeds, and Tapping – .D = Tool Diameter in inches. Milling Feed. The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter. On the milling machines we have here at LBCC, the feed is independent of the spindle speed. This is a good arrangement and it permits faster feeds for larger, slowly rotating cutters.
