Introduction to the composition and measurement principle of the three-coordinate measuring machine! Published: 2019-11-22 Source: https://www.microaccuracy.com/ Three-coordinate measuring machine is an indispensable important equipment for modern industrial inspection and quality control. It can achieve three-dimensional accurate measurement. There are extensive applications in the production field. In order to let everyone know more about the coordinate measuring equipment, the following Miaoji introduces the composition and measurement principle of the coordinate measuring machine! The coordinate measuring machine is based on the coordinate position of the point. Its measuring principle is to put the measured part into its allowable measuring space, and accurately measure the value of the measured part at the three coordinate positions of X, Y, and Z. The numerical values u200bu200bof these points are processed by computer data and fitted to form measurement elements. After mathematical calculations, accurate data of shape, position tolerance and other geometric quantities are obtained. In order to achieve high-precision measurement, the three-coordinate is composed of a complex structure, which includes a number of important systems: Probe system: The probe system includes probes, suction cups, probes, reading heads, and grating rulers. An important part of making contact. Hardware control system: With computer-aided error correction function, it can make real-time dynamic corrections to CMM and sensors to ensure that the coordinate measuring machine obtains accurate measurement results. Electric drive system: including motor, friction roller, steel belt, belt, air cushion (air bearing), air pipe, filter, barometer, pressure regulating valve. Other mechanical parts: including granite countertops, three-axis guide rails, shock absorbers, support base frames, Z-axis balancing cylinders, solenoid valves, etc. Data processing software system: Different brands of coordinate measuring machines use different software systems. With this software, CAD data can be converted into measurement programs, so as to obtain an accurate detection plan. The coordinate measuring machine can not only complete various complex measurements under computer control, but also realize the control of processing by exchanging information with CNC machine tools, and can also realize reverse engineering based on the measurement data. Therefore, it currently plays a huge role in precision testing in various fields. As a large domestic measuring equipment manufacturer, MiaoJi can currently provide a variety of high-quality three-coordinate measuring machines and one-button measuring instruments!
