    - This machine measures linear dimensions, location and roundness of holes, pitch and diameter of threads, flatness, perpendicularity of surfaces, etc

    - It is a combination of tool maker's microscope and contact type optical measuring machine.


    Co-ordinate measuring machines

    - Co-ordinate measuring machines are used for layout and inspection of complex components. They are also used as an integral part of FMS system. They are 3-D marking and measuring systems used for accurate measurement.

    - Different types of controls used in computer controlled co-ordinate measuring machines are:

    1) Direct computer control

    2) Motorized computer control

    3) Computer assisted manual control

    4) Manual control
