  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. CNC plunge milling - Wikipedia

    en.wikipedia.org/wiki/CNC_plunge_milling

    CNC plunge milling, also called z-axis milling, is a CNC milling process. In this process, the feed is provided linearly along the tool axis while doing CNC processing. This image shows the material removal in plunge milling. Plunge milling is effective for the rough machining process of complex shape or free form shapes like impeller parts. In ...

    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.

    Spindle speed is derived from cutting speed and feed rate is mixed in with it, so cutting speed won the toss. it took a while to get my head around it but I think it's sorted now. Onto the next project, all going well of course. Feed rate and spindle speed are now redirects, as is speeds and feeds — Graibeard 12:09, 9 September 2005 (UTC)

  6. 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.

    The CNC Machine can be either a moving gantry style, where the table is fixed and the router spindle moves over it, or fixed bridge design, where the table moves underneath the router spindle, or hand-held style, where the operator moves the machine to the area to be cut and the machine controls the fine adjustments.

    The New York Jets have once again been eliminated from the NFL playoff picture, pushing their league-worst drought to 14 seasons.

  9. Material removal rate - Wikipedia

    en.wikipedia.org/wiki/Material_removal_rate

    Material removal rate (MRR) is the amount of material removed per time unit (usually per minute) when performing machining operations such as using a lathe or milling machine. The more material removed per minute, the higher the material removal rate. [1] [2] The MRR is a single number that enables you to do this. It is a direct indicator of ...
