Speed, Feed, and Depth of Cut. 1. Cutting speed is defined as the speed (usually in feet per minute) of a tool when it is cutting the work. 2. Feed rate is defined as tool's distance travelled during one spindle revolution. 3. Feed rate and cutting speed determine the rate of material removal, power requirements, and surface finish. 4.

• #### Milling (machining) - Wikipedia

The speed at which the piece advances through the cutter is called feed rate, or just feed; it is most often measured in length of material per full revolution of the cutter. There are two major classes of milling process: In face milling, the cutting action occurs primarily at the end corners of the milling cutter. Face milling is used to cut flat surfaces (faces) into the workpiece, or to cut flat-bottomed cavities.
