A Universal Measuring Machine (UMM) is a measuring device for objects where geometric relationships are the most critical element, where dimensions are specified by geometric positions (see GD&T) rather than absolute coordinates. [1] The original use of these machines was to inspect gages and parts

Development of the first CMM coordinate measuring machine.Research shows that the development of modern 3-axis machines began in the early 1960s and is a direct descendant of modern 2-axis metrology machines invented in the 50s in various military defense industries.The first 2-axis universal measur

With the development of modern manufacturing industry, the design requirements for mechanical manufacturing products are getting higher and higher, and the three-coordinate measuring instrument has been widely used in many industries. Improve the efficiency of the three-coordinate measuring instrument, which can make the detection results more effective.
