The measurement error of articulated arm coordinate measuring machine is affected by various factors, and the error caused by the physical component cannot be eliminated. This paper aims to construct a virtual articulated arm coordinate measuring machine. First, the measuring machine's kinematics model was built by using D-H (Denavit-Hartenberg) matrix. Then the measuring machine's data was analyzed by utilizing PC-DMIS measurement software and the accuracy of the model was tested. Finally, the simulation was carried out with Monte Carlo method. By comparing the models constructed with the actual parameters and the manufacturer parameters, it is showed that the measuring accuracy of the established measuring machine's model can satisfy requirements. The result of simulation indicates that the virtual model and the testing method we proposed are of great engineering value to the application of the coordinate measurement.
