摘要：
This paper proposed a systematic method to identify and compensate the geometric errors of non-orthogonal five-axis machine tools. An efficient ballbar test with a 45° wedge is designed to decouple the position-dependent and independent geometric errors for the non-orthogonal rotary axis. The geometric errors of translational axes are measured by step-size body diagonal tests based on a laser interferometer. After all the error items are measured, the volumetric error is precisely predicted and compensated based on the screw theory. The proposed geometric error identification and compensation strategy are experimentally verified via cone frustum tests on a DMG non-orthogonal five-axis machine.
