What are the three coordinates for?

Three coordinates are used to detect geometric tolerance, including: measurement of geometric elements: point, line, circle, surface, ball, arc, ellipse, cylinder, cone, keyway, curve and surface; The construction of geometric elements: projection, bisection, intersection, tangency, mirror image, fitting, translation, vertical, parallel, combination, rotation, offset line and offset; Form and position tolerance software: straightness, flatness, roundness, cylindricity, taper, sphericity, distance, included angle, verticality, parallelism, inclination, position (2D and 3D), symmetry, coaxiality, concentricity, etc.

The measuring principle is that the measured object is placed in the measuring space of CMM, and the values of points on the surface of the measured part are accurately measured at three coordinate positions in space by using contact or non-contact detection system, and then the spatial coordinate values of these points are fitted to form measuring elements, such as circles, spheres, cylinders, cones and curved surfaces. The geometric size, shape and position to be measured are calculated by software.

Application: CMM is mainly used for measuring boxes, racks, gears, cams, worm wheels, worms, blades, curves and curved surfaces in machinery, automobile, aviation, military industry, furniture, tool prototypes, machinery and other industries. It can also be used in electronics, hardware, plastics and other industries, and can accurately detect the size, shape and shape tolerance of workpieces, thus completing tasks such as part detection, shape measurement and process control.
