Special Issue Information

Dear Colleagues,

Modern machines are becoming more structurally complex and operate under harsher loading and operational conditions. To ensure the efficient and reliable operation of machines, reduced unscheduled downtime, and lower operation and maintenance costs, it is necessary to develop intelligent fault diagnostic methods and assess their health state for the aim of identifying the mode, type, severity, and degradation trend of faults.

This Special Issue encourages and welcomes original research articles on machine fault detection, diagnosis, and prognosis. Potential topics include, but are not limited to, the following:

  • Fault diagnosis methods based on various sensor data;
  • Signal processing;
  • Fault model research with changeable variable transfer path;
  • Fault diagnostics under non-stationary operating conditions;
  • Fault prediction;
  • Machine-learning-based fault diagnostics and condition monitoring;
  • Fatigue analysis of machinery.

Abstract
Traditional data-driven tool wear state recognition methods rely on complete data under targeted working conditions. However, in actual cutting operations, working conditions vary, and data for many conditions lack labels, with data distribution characteristics differing between conditions.

Traditional data-driven tool wear state recognition methods rely on complete data under targeted working conditions. However, in actual cutting operations, working conditions vary, and data for many conditions lack labels, with data distribution characteristics differing between conditions. To address these issues, this article proposes a method for recognizing the wear state of milling cutters under varying working conditions based on an optimized symmetrized dot pattern (SDP). This method utilizes complete data from source working conditions for representation learning, transferring a generalized milling cutter wear state recognition model to varying working condition scenarios. By leveraging computer image processing features, the vibration signals produced by milling are converted into desymmetrization dot pattern images. Clustering analysis is used to extract template images of different wear states, and differential evolution algorithms are employed to adaptively optimize parameters using the maximization of Euclidean distance as an indicator. Transfer learning with a residual network incorporating an attention mechanism is used to recognize the wear state of milling cutters under varying working conditions. The experimental results indicate that the method proposed in this paper reduces the impact of working condition changes on the mapping relationship of milling cutter wear states. In the wear state identification experiment under varying conditions, the accuracy reached 97.39%, demonstrating good recognition precision and generalization ability. Full article
