  2. Coordinate-measuring machine - Wikipedia

    en.wikipedia.org/wiki/Coordinate-measuring_machine

    A coordinate-measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensors do exist.

  3. Cylindrical coordinate measuring machine - Wikipedia

    en.wikipedia.org/wiki/Cylindrical_Coordinate...

    This is an example of a Cylindrical Coordinate Measuring Machine (CCMM), a special type of CMM that uses a rotating table to move the part relative to the inspection probe. In this case the CCMM is a camera and telecentric lens system, which is fitted with a tactile probe.

    en.wikipedia.org/wiki/Romer_arm

    A ROMER Arm is a term for a portable coordinate measuring machine ROMER, a company Acquired by the Hexagon AB group, and part of the Manufacturing Intelligence division, designed the ROMER arm in the 1980s to solve the problem of how to measure large objects such as airplanes and car bodies without moving them to a dedicated measuring laboratory.

  5. Dimensional metrology - Wikipedia

    en.wikipedia.org/wiki/Dimensional_metrology

    Modern measurement equipment includes hand tools, CMMs (coordinate-measuring machines), machine vision systems, laser trackers, and optical comparators.A CMM is based on CNC technology to automate measurement of Cartesian coordinates using a touch probe, contact scanning probe, or non-contact sensor.

  6. Touch probe - Wikipedia

    en.wikipedia.org/wiki/Touch_probe

    The development of precision probes dates back to the 1920s with different mechanical touch devices, but significant advancements came with the advent of Coordinate Measuring Machines (CMM) in the late 1950s. This led to the creation of contact and non-contact probes, including mechanical triggers and scanning probes, as well as laser and ...
