Coordinate measuring machine(CMM) is one of the most efficient ways to measure and obtain dimensional data because it can replace multiple measuring tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes. The function of the CMM is to quickly and accurately evaluate the dimensional data, providing the operator with useful information about the state of the production process, which is very different from all manual measuring equipment. For mechanical parts with complex shapes, which need to measure free-form surfaces, CMM is more suitable.
