Summary: This paper presents a general approach to identifying both kinematic and non-kinematic faults in error motion trajectory data by framing the issue as a generic pattern recognition problem. The sparse nature of datasets in this domain leads to training on a purely simulated dataset, and ensemble methods are shown to improve generalizability when predicting on experimental data. A transfer learning approach is introduced to incorporate experimentally-obtained data into classifiers trained primarily on a simulation domain.

Summary: Assembly geometric error, a part of machine tool system errors, significantly affects the machining accuracy of multi-axis machine tools. Its non-uniform distribution in the working space cannot be eliminated due to error propagation during the assembly process. To overcome the limited expression ranges of existing models, a modeling methodology based on the Jacobian-Torsor model is proposed to describe the spatially distributed geometric errors. Simulation and experimental verification on five four-axis machine tools demonstrate the effectiveness of the proposed model in dealing with the spatial expression of assembly geometric errors.
