Milling tools are critical to machining and manufacturing processes. Accurate diagnosis identification of faults occurring in milling during their operation utmost importance for maintaining the reliability availability these tools, minimise machine downtime overall costs. This paper presents a fault network model based on acoustic emission signals. The integrates multilayer wavelet CNN (MWN) consisting discrete transform (DWT) convolutional neural (CNN), block attention module (CBAM), PatchTST module. MWN uses transformation withdraw multi-scale features from signals, thus improving sensitivity small variations emission. CBAM improves feature representation by focusing channels regions, while self-attention mechanism optimise processing long-range dependencies. synergy mechanisms results superior performance, outperforming traditional diagnostic methods. Bayesian optimisation is used select hyperparameters, eliminating subjective bias associated with manual range setting. Validation experiments using dataset, including ablation studies comparative tests, demonstrated that achieves an accuracy over 98%, validating its generalisation capability effectiveness diagnosing tool

Abstract Many deep learning methods typically assume that the marginal probability distribution between training and testing bearing data is similar or same. However, of rolling bearings may deviate significantly under diverse working conditions. To address above limitations, a novel transferable remaining useful life (RUL) prediction method integrated with Bayesian unsupervised domain adaptation (DA) proposed. First, signal alignment executed on after first time to maintain same granularity scale across both source target domains. Second, multi‐domain features are extracted sent into dual‐channel Transformer network (DCTN) incorporating convolutional block attention module (CBAM) adequately exploit abundant degradation information. Then, DA incorporated model mitigate discrepancies high‐level merged Finally, by applying variational inference method, DCTN‐CBAM extended neural network, RUL its corresponding confidence intervals can be conveniently derived. In addition, generalization capability effectiveness validated through six bidirectional transfer tasks two datasets. The experimental results demonstrate it could provide more reliable efficiently account for uncertainty.
