Three coordinate measuring instrument(CMM)
Three coordinate measuring instrument is through the basic coordinates of three-dimensional space, using the measurement method of geometric elements, including point, line, surface, circle, ball, cylinder, cone, etc., to some complex and precise workpiece size, shape and shape tolerance and high-precision geometric parts of the surface, complex shape of mechanical parts, Continuous scanning to complete parts inspection, shape measurement, process control and other tasks, it is now widely used in precision parts, precision mold, precision manufacturing, military, aviation and automobile manufacturing and other fields
