Diagnostics for geometric performance of machine tool linear axes



Gregory W. Vogl, M A. Donmez, Andreas Archenti


Machine tools degrade during operations, yet knowledge of degradation is elusive; accurately detecting degradation of linear axes is mainly a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the condition of their machine tool linear axes with minimal disruptions to production. A method was developed to use data from an inertial measurement unit (IMU) for identification of translational and angular error changes due to axis degradation. A linear axis testbed, established for the purpose of verification and validation, revealed that the IMU-based method was capable of resolving linear axis errors with acceptable test uncertainty ratios.
