| Abstract: | The modeling and identification technologies for errors of machining center are studied. Based on the theory of multi-body system and characteristic modeling method of posi-tion and gesture, the general volumetric error model of ma-chining center is established. Based on the volumetric error model, a new displacement technology for the identification of geometric errors of machining center is proposed. Finally, ac-cording of the proposed modeling methods, the specific error model of a 3-axis vertical machining center is given, and its error identification results are obtained based on the new dis-placement method. |
