what does cmm mean?

A coordinate measuring machine is one of the effective methods for measuring and obtaining dimensional data because it can replace a variety of surface measuring tools and expensive combined gauges, and reduce the time required for complex measuring tasks from hours to minutes. The function of the coordinate measuring machine is to quickly and accurately evaluate the dimensional data, providing the operator with useful information about the state of the production process, which is quite different from all conventional quantities. The object to be measured is placed in the coordinate measuring space, and the coordinate positions of the measuring points on the measured object can be obtained. According to the spatial coordinate values of the points, the geometric size, shape and position of the measured object are calculated.

    The coordinate measuring machine is composed of a host computer, a software system, an electrical (control) system and a probe system. The following content is mainly introduced on different types of coordinate measuring machines.

 The basic hardware of the measuring machine has a variety of structural forms:

    1. Activity bridge type:

    The movable bridge measuring machine is a widely used form of mechanism. The feature is that the opening is better, the field of view is wide, and the upper and lower parts are convenient. The movement speed is fast and the precision is relatively high. There are several types of small, medium and large.

  2, fixed bridge type:

    The fixed bridge type measuring machine is fixed by the bridge, has good rigidity, and the center of the moving table is driven, and the center grating Abe error is small. The above characteristics make the measuring machine of this structure very high precision, and it is a suitable structure of the measuring machine with high precision and ultra high precision. .

 3. Viaduct type (gantry type):

    The viaduct measuring machine is suitable for large and very large measuring machines and is suitable for the measurement of large parts or large molds in the aerospace, aerospace and shipbuilding industries. Generally, double grating, double drive and other technologies are used to improve the accuracy.

  4, horizontal arm type;

    The horizontal arm measuring machine has good openness and large measuring range. It can be composed of two machines to form a dual-arm measuring machine, which is especially suitable for the measurement of Sheet metal parts in the automotive industry.

    5, articulated arm type.

    The articulated arm measuring machine has very good flexibility and is suitable for carrying to the field for measurement, and the environmental conditions are relatively low.
