Abstract:

Double parallel-joint coordinate measuring machine (CMM) is a new type of coordinate measuring devices. An improved four-parameter DH model is used to deduce the double parallel-joint CMM measurement model. Error model of the double parallel-joint CMM is discussed based on the measurement model. Compared with the ideal model, correctness of the measurement model is verified by the error model. This forms a theoretical basis for designing and error distribution of double parallel-joint CMM.

Key words: coordinate measuring machine, mathematical model, DH model
