Research on a New Identification Approach of B Rotary Axe Geometric Error for Non-orthogonal Five-Axe CNC Machine Tool

Abstract

This paper present on an new error identification approach on B rotary axe geometric error for a non-orthogonal five-axe CNC machine tool research is not enough in the domestic and abroad, establish the motion error model of non-orthogonal five-axe CNC machine tool based on the multi-body system theory (MBS), there are total 12 static errors and dynamic errors in this model. Design eight different measurement method to measure 12 errors. Finally realizing 12 errors identification of the B rotary axe by combine measurement results. This approach can be used for the rotary axe error identification of five-axe CNC machine tool and the measurement results are accurate after test verification.
