This paper describes a method for identifying geometric deviations using measured trajectories of simultaneous five-axis motion in five-axis machining centers with a tilting rotary table. The method for identifying the geometric deviations by using measured data have not been reported although the methods using the results of the simulation have been reported. As the mechanical errors such as pitch error and backlash of worm gears are included in the measured trajectories besides the components of geometric deviations, the accurate values of geometric deviations have not been identified. In this paper, the effect of those errors on the identified values is investigated through simulation. It is found that the backlash which is a non-linear error largely affects the identified values, but the pitch error does not affect them. If the backlash in the tilting axis can be compensated completely, the inherent geometric deviations to the five-axis machine can be identified from the measured data using the observation equations and geometric relations.
