    en.wikipedia.org/wiki/Coordinate-measuring_machine

    The first CMM was developed by the Ferranti Company of Scotland in the 1950s [1] as the result of a direct need to measure precision components in their military products, although this machine only had 2 axes. The first 3-axis models began appearing in the 1960s (made by DEA of Italy and LK of the UK), and computer control debuted in the early ...

  8. 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.

  9. Multiaxis machining - Wikipedia

    en.wikipedia.org/wiki/Multiaxis_machining

    CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
