摘要
Abstract
A new method is proposed in this paper, that the double bal bar is used as the measuring instrument to measure and i-dentify the geometric error of a trunnion-type A-axis. The derivations of the center of the bal are measured on 3 instal ation sife of the rotation table by double bal bar with circular paths in the error sensitive directions and an homogenous transform matrices is used to build the identification model. Four linkage errors and six volumetric errors are obtained by a two-step identification procedure. Final-ly, the validity of proposed method is validated by practical tests on the five-axis machine center.关键词
