英文摘要：

To overcome the defects of the traditional measuring machine using Cartesian coodinate system, the ideal mathematical models of the articulated arm CMM were established by using Denavit-Hartenberg analysis arithmetic. An improved genetic algorithm was presented for the parallel recombination simulated annealing. The algorithm employed a modified multi-pointed crossover operator, an adaptive mutation operator and a modified elitist strategy to ensure the accuracy of calibration. Experiments were carried out for a Faro platinum 4fl articulated arm CMM, and the experimental results convincingly show the high performance of the proposed method based on reversal process, which establishes an academic foundation for increasing the accuracy.
