Research Review of Coordinate Measuring Machines

The fourth industrial revolution driven by digitalization, networking and intelligence has put forward new requirements for Coordinate Measuring Machines (CMMs). Two important development directions of Coordinate Measuring Machines are reviewed and analyzed in this paper. The first is the study of error compensation of Coordinate Measuring Machines, which includes the study of dynamic and static error and the study of dynamic error compensation technology. Dynamic error compensation is particularly important in high-speed measurement. And how to ensure measurement accuracy in high-speed measurement is an important direction for the development of Coordinate Measuring Machines. The second is about the intelligence of Coordinate Measuring Machines which includes CAD/CMM integration, independent decision-making, inspection planning, collision prevention and position recognition of the measured workpiece.
