This research work was conducted to confirm the effectiveness of the checking method specified by ISO 10791-6 and to propose an additional method for identifying the geometric deviations inherent to five-axis machining centers with a universal spindle head. In the simulation, it was assumed that a telescopic ball bar system was used for the measurement of trajectory, which was described by the spherical interpolation movement specified in the clause K6 of the standard. The influence on the trajectories of peculiar ten deviations to five-axis machining centers was investigated. However, two of the ten deviations were only extracted and the other eight deviations have not been extracted, although an observation equation was applied to the identification. Then, an alternative spherical movement based on the clause K6 of the ISO standard was designed. In this method, the ball of the ball bar system of the spindle side was magnetically fixed on a special arm which was mounted on the spindle nose. The observation equation was applied to the measured trajectory, and four deviations were identified. Furthermore, four rests of ten deviations were identified by analyzing the geometrical relations. The exactness of the proposed procedures to identify the deviations inherent to the 5-axis machine was confirmed through the simulations.
