Abstract
This paper proposes a method for the identification of all of the geometric deviations in five-axis machining centers by simultaneous multi-axis motion. In our previous study, ignoring the squareness deviations among translational axes, eight geometric deviations about rotational axes have been identified successfully. However, the machining centers have in general some squareness deviations. Thus, the influence of the squareness deviations on the circular trajectories under simultaneous three-axis motion was analyzed, and the squareness deviations among the translational axes were corrected. Using the proposed method, the eight geometric deviations were correctly identified.
