Which industries have the coordinate measuring machines of automatic image measuring instruments developed and applied to? The emergence of the coordinate measuring machine is the historical necessity of the development of industrialization. On the one hand, it is due to the development of high-efficiency processing such as automatic machine tools and CNC machine tools, and the processing of more and more complex-shaped parts requires fast and reliable measuring equipment; on the other hand, due to electronic technology, computer technology, CNC technology and precision The development of processing technology provides the technical basis for it. The appearance of the coordinate measuring machine makes it possible to change the measuring instrument from manual mode to modern automatic measurement.
    Different from the traditional measuring instruments that compare and measure the measurand and the mechanical reference, the measurement of the coordinate measuring machine is actually based on the collection and calculation of the coordinates of the spatial point. Although modern measuring machines are much more advanced than the earlier ones, the basic principle is the same, that is, to build a rigid structure with three mutually perpendicular axes, each axis is equipped with a grating ruler, and is defined as X, Y and Z axes. To allow each shaft to move, each shaft is fitted with an air bearing or mechanical bearing.

    The detection system on the vertical axis records the position of the measurement point at any one time. The detection system is generally composed of a probe and a touch probe. The probe is in slight contact with the surface of the workpiece to be measured to obtain the coordinates of the measurement point. In the measurement process, the coordinate measuring machine converts the measurement of various geometric elements of the workpiece into the coordinate positions of the points on these geometric elements, and then the software calculates the size, shape and relative position of these geometric elements according to the mathematical model of the corresponding geometric shape. and other parameters.

    As a precise and efficient space length measuring instrument, the coordinate measuring machine can realize the measurement work that many traditional measuring instruments cannot complete, and its efficiency is ten times or even dozens of times higher than that of traditional measuring instruments. Moreover, the coordinate measuring machine is easy to connect with CAD, and the measurement results are fed back to the design and production departments in real time, so as to improve the product design or production process. So CMMs have and will continue to replace many traditional length measuring instruments.
