Abstract: T he
modeling and identification technologies for errors of machining
center are studied, Based on the theory of multi-body system and
characteristic modeling method of position and gesture, the
general volumetric error model of machining 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, according 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
displacement method.
Key words: Machining
