  2. Speeds and feeds - Wikipedia

    en.wikipedia.org/wiki/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 100 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.

  3. Milling (machining) - Wikipedia

    en.wikipedia.org/wiki/Milling_(machining)

    The speed at which the piece advances through the cutter is called feed rate, or just feed; it is most often measured as distance per time (inches per minute [in/min or ipm] or millimeters per minute [mm/min]), although distance per revolution or per cutter tooth are also sometimes used.

  4. Surface feet per minute - Wikipedia

    en.wikipedia.org/wiki/Surface_feet_per_minute

    Surface feet per minute (SFPM or SFM) is the combination of a physical quantity (surface speed) and an imperial and American customary unit (feet per minute or FPM).It is defined as the number of linear feet that a location on a rotating component travels in one minute.

    As for re-deriving the formulas on one's own, it seems to me that a distinction can be made between formulas depending on whether feed is being measured in terms of per-revolution or per-minute . If the former (G94), then you need all three—feed, speed, and depth of cut (DOC)—to figure out the volume being swept through (turned into chips ...

  6. Tool wear - Wikipedia

    en.wikipedia.org/wiki/Tool_wear

    This is somewhat normal for tool wear, and does not seriously degrade the use of a tool until it becomes serious enough to cause a cutting edge failure. Can be caused by spindle speed that is too low or a feed rate that is too high. In orthogonal cutting this typically occurs where the tool temperature is highest. Crater wear occurs ...

    The tool will then feed perpendicularly across the part's rotational axis as it spins in the jaws of the chuck. A user will have the option to hand feed the machine while facing, or use the power feed option. For a smoother surface, using the power feed option is optimal due to a constant feed rate. Facing will take the work piece down to its ...
