The measurement errors of a CNC coordinate measuring machine is known to depend on machine adjustment carried out in the final assembling process. The purpose of this study is not only to identify the factors in the adjustment procedure that have large effect on accuracy of measurement, but also thereby to improve the efficiency and the performance of adjustment. Experiment was performed on the direct product of orthogonal arrays L_<36> and L_<27> which were assigned adjustment and measurement conditions, respectively. Analyses were carried out from the viewpoints of error magnitude and dispersion. The rigidity of the air bearing of Y axis was found to have the largest effects on the dispersion, but not on the magnitude. The perpendicularity in various planes are found to have the second largest contribution to both the magnitude and the dispersion. Efficiency of the adjustment procedure was improved significantly on the basis of these results.
