  2. Milling (machining) - Wikipedia

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

    The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers : milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures.

  3. Machining - Wikipedia

    en.wikipedia.org/wiki/Machining

    Milling operations are operations where the cutting tool with cutting edges along its cylindrical face are brought against a workpiece to remove material in the profile of the spinning tools shaft and lower edge. [7] Milling machines are the principal machine tool used in milling. Advanced CNC machines may combine lathe and milling operations.

  4. Tool and cutter grinder - Wikipedia

    en.wikipedia.org/wiki/Tool_and_cutter_grinder

    The D-bit (after Friedrich Deckel, [1] the brand of the original manufacturer) grinder is a tool bit grinder designed to produce single-lip cutters for pantograph milling machines. Pantographs are a variety of milling machine used to create cavities for the dies used in the molding process ; they are largely obsolete and replaced by CNC ...

  5. Three roll mill - Wikipedia

    en.wikipedia.org/wiki/Three_roll_mill

    A three roll mill or triple roll mill [1] is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.

  6. Machine tool - Wikipedia

    en.wikipedia.org/wiki/Machine_tool

    Eli Whitney milling machine, c. 1818. Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized ...

  7. Mill (grinding) - Wikipedia

    en.wikipedia.org/wiki/Mill_(grinding)

    Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purposes, or separation of rock, soil or aggregate material for the purposes of structural fill or land reclamation activities.

  8. Automatic tool changer - Wikipedia

    en.wikipedia.org/wiki/Automatic_Tool_Changer

    In machining, an automatic tool changer (ATC) is used in computerized numerical control (CNC) machine tools to improve the production and tool carrying capacity of the machine. ATCs change tools rapidly, reducing non-productive time. They are generally used to improve the capacity of the machines to work with a number of tools.

  9. 2.5D (machining) - Wikipedia

    en.wikipedia.org/wiki/2.5D_(machining)

    A 2.5D machine, also called a two-and-a-half-axis mill, possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time due to hardware or software limitations, or a machine that has a solenoid instead of a true, linear Z axis. A typical example involves an XY table that ...
