How to interpret the three-coordinate measurement report

Coordinate measuring machine (CMM) refers to an instrument that can display geometric shape, length and circumferential indexing measurement ability in a hexahedral space, also known as CMM or CMM. A three-coordinate measuring instrument can be defined as "an instrument with a detector that can move in three directions and on three mutually perpendicular guide rails.". The detector transmits signals in a contact or non-contact manner, and the three-axis displacement measurement system (such as an optical ruler) calculates the coordinates (x, y, z) of each point of the workpiece through a data processor or computer and measures various functions. " The measuring function of three-coordinate measuring instrument should include dimensional accuracy, positioning accuracy, geometric accuracy and contour accuracy. Application field of three-coordinate measuring instrument:? Measuring high-precision geometric parts and surfaces; ? Measuring mechanical parts with complex shapes; ? Detecting a free-form surface; ? Contact or non-contact probe can be selected for continuous scanning. Working energy of three-coordinate measuring instrument:? Measurement of geometric elements, including points, lines, surfaces, circles, spheres, cylinders, cones, etc. ? Curve and surface scanning, supporting point scanning function, IGES file data output, CAD nominal data definition, ASCII text data input, nominal curve scanning, contour analysis conforming to tolerance definition. ? Calculation of form and position tolerance, including straightness, flatness, roundness, cylindricity, verticality, inclination, parallelism, position, symmetry, concentricity, etc. ? Support traditional data output report, graphical inspection report, graphical data labeling, data label output and other output methods. Features of CMM equipment:? Are the core components and software imported? Unilateral movable bridge structure can significantly improve the motion performance and ensure the measurement accuracy and stability? The three-axis guide rails are all made of high-precision natural granite and have the same temperature characteristics and stiffness. The three-axis guide rail adopts self-cleaning and pre-tightening high-precision air bearing, which makes the movement more stable and the guide rail never wears? RENISHAW self-adhesive open metal grating ruler is closer to the thermal expansion coefficient of granite matrix, which improves the stability of the equipment. RENISHAW UCC high-speed and high-precision automatic control system, embedded with 32-bit microprocessor, truly realizes real-time control; The upper and lower parts adopt optical fiber communication, which enhances the electrical anti-interference ability. What are the characteristics of SEREIN DMIS software? The software runs in the WINDOWS 2000/XP environment, with a full Chinese interface; Object-oriented programming mode, supporting graphic mirroring function. ? 3D CAD digital-analog import, entity or wireframe model reproduction, DMIS and STEP file import and export, measurement results IGES file output, supporting reverse engineering. ? The dynamic coordinate measuring machine model supports the simulation of measuring machine and probe and the graphic library of RENISHAW probe. ? Probe management function, which can dynamically select various probes. ? Measurement of geometric elements, including points, lines, surfaces, circles, spheres, cylinders, cones, etc. ? Curve and surface scanning, supporting point scanning function, IGES file data output, CAD nominal data definition, ASCII text data input, nominal curve scanning, contour analysis conforming to tolerance definition. ? Calculation of form and position tolerance, including straightness, flatness, roundness, cylindricity, verticality, inclination, parallelism, position, symmetry, concentricity, etc. ? Support traditional data output reports, graphical inspection reports, graphical data labeling, data label output and other output methods; ? Workpiece coordinate system management, specifying datum plane (axis) can generate workpiece coordinate system, realize translation and rotation of coordinate system and mutual conversion between Ducal coordinate and polar coordinate, and support 3-2- 1 alignment. ? Error compensation function to further improve the measuring accuracy of the machine. Basic technical parameters of coordinate measuring machine: model: MMF?
