Overview of intelligent CMM guidance technology

With the development of machinery industry and the increasing level of manufacturing intelligence, the quantity of measured parts is more and more, and the precision requirement is higher and higher, the three-coordinate measuring machine (CMM) has a higher level of intelligence requirements. Firstly, this paper introduces the measuring principle of the intelligent CMM and its guiding technology, which can determine the position of the parts to be measured on the CMM workbench and save the labor cost, then, the research progress of guidance technology is summarized from the aspects of the types, advantages and disadvantages of guidance technology. Finally, the future research focus and development direction of guidance technology are prospected. This technology has high research space and value in the research of part measurement scheme, and it is also the development direction in the future.
