KINEMATIC CALIBRATION AND COMPUTER SIMULATION OF 3 DOF PARALLEL-LINK CMM

Abstract

Abstract: Firstly, the structure, measuring theory and characteristics of a new kind of coordinate measuring machine (CMM) using parallel-link mechanism with three spatial degrees of freedom (3 DOF) is described. Then, an algorithm based approach for kinematic calibration of 3 DOF parallel-link CMM is presented, and twenty-two main kinematic parameters of the CMM are identified using the offered method. Finally, the identification results are verified by computer simulation. It lays the theoretical foundation for further improving the measuring accuracy of the studied parallel-link CMM.

Key words: CMM, Computer simulation, Kinematic calibration, Parallel-link mechanism
