However, certain aerospace nuts undergo over 120 h of rigorous testing per batch, causing increased costs and delayed product delivery. Therefore, accurately predicting production quality and remaining testing time (RTT) is crucial for improving efficiency. Facing this new challenge, this paper proposes a data-model hybrid time series prediction method based on quality information fusion. First, considering that the monitoring data contains two sets of related features, we introduce a multi-task parallel deep learning (MTL) network with a temporal self-attention mechanism (TSAM). The TSAM assigns importance to key degradation information, while MTL leverages shared feature information to capture more accurate long-term trends. Next, considering the multi-stage nature and uncertainty of the degradation process, a semi-empirical physical degradation model is constructed, where stage identification is achieved using the Pruned Exact Linear Time (PELT) method, and uncertainty is estimated through Particle Filtering (PF). The Bayesian framework enables hybrid correction between the data-based and the model-based methods, integrating the strengths of both. Finally, experimental results demonstrate that the proposed method outperforms traditional models, effectively achieving more accurate quality predictions.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"82 ","pages":"Pages 1171-1191"},"PeriodicalIF":14.2,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capitalizing on this strength, a growing number of fault diagnosis models have been developed to monitor CNC machine tools, which are essential to modern manufacturing. These machines operate under demanding conditions – characterized by high speeds and heavy loads – and consequently generate mechanical signals with pronounced nonlinearity. Such inherent nonlinearity poses significant challenges for conventional feature extraction methods, necessitating advanced self-supervised techniques to effectively capture and interpret the underlying fault-related features for reliable condition monitoring. In this research, we introduce a self-supervised time–frequency feature alignment (STFA) algorithm for monitoring the manufacturing processes of industrial CNC machine tools. The STFA algorithm initially employs two domain-specific modules to extract time–frequency features from surveillance signals. A modern CNN is utilized to extract spatiotemporal information from the time domain, while a multi-scale CNN captures multi-granular features from the frequency domain. Subsequently, a dedicated time–frequency feature alignment module (TFAM) maps these features into a unified space, thereby exploiting their complementarity and enabling a more comprehensive representation. The STFA algorithm is trained through a dual-stage process—first, a pre-training phase to establish robust feature representations from unlabeled data, followed by a fine-tuning stage using a limited number of labeled samples to adapt the model for precise fault diagnosis. The effectiveness of the proposed STFA algorithm is validated using two manufacturing datasets collected from industrial CNC machine tools.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"82 ","pages":"Pages 1145-1157"},"PeriodicalIF":14.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CT integrates real-time physical signals from force, vibration, and vision sensors by leveraging a synergistic ensemble of advanced artificial intelligence (AI) modules, such as Extreme Gradient Boosting (XGBoost), ConvNeXt V2, Efficient Sub-Pixel Convolutional Networks (ESPCN), stacked sparse autoencoder with supervision (SSAES), large language models (LLM), and reinforcement learning (RL).

This holistic integration bridges the physical, semantic, and cognitive layers of CNC machining, supporting robust, transparent, and operator-oriented decision-making. The proposed system was validated through ultrasonic vibration-assisted blade dicing (UVABD) experiments. CT reduced dicing force prediction error by 39.86 %, improved tool wear prediction accuracy by 29.59 %, and decreased edge chipping severity by 60.47 % compared to the baseline model.

Since there may be different representations and descriptions of identical process knowledge, it is necessary to mine deep semantic information to achieve process generation. To address these challenges, we propose a knowledge graph embedding-based similarity matching model for intelligent assembly process generation. First, we build a knowledge graph embedding-based similarity matching model called KGESM.

While high-resolution industrial cameras are widely used, detecting tiny defects across hundreds of unit cells remains a significant challenge. Additionally, imbalanced defect data distributions in industrial environments exacerbate the detection challenge. To address these, a novel framework specifically designed for lead frame surface defect detection is proposed. The framework consists of two main components: multi-scale geometric constraint matching (MGCM) and dual-branch attention-based normality recall (DB-ANR). MGCM is a specialized algorithm designed for array-structured detection, efficiently extracting unit cells from high-resolution images by leveraging geometric constraints and eliminating redundant matching points, ensuring stable and precise results. DB-ANR addresses data imbalance and normal pattern forgetting by training on normal data to store patterns, which are recalled during inference to enhance detection accuracy. Additionally, the adaptive local–global dual attention module dynamically balances the contributions of local and global features, enabling robust detection across various defect types. Experiments on a self-constructed dataset with five types of lead frames demonstrate the effectiveness of the proposed framework. MGCM reliably extracts unit cells from high-resolution images, while DB-ANR achieves an AUC of 97.76%, PRO of 89.12%, and F1-score of 81.6%. The model also demonstrates efficient memory usage and fast inference speed, meeting deployment requirements in real industrial scenarios. Furthermore, the proposed array-oriented detection framework is not limited to lead frames and can be extended to other semiconductor applications, such as chip and wafer quality detection, where similar array-structured patterns exist.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"82 ","pages":"Pages 1091-1109"},"PeriodicalIF":14.2,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144842094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a new task allocation scheme based on single-limb actions to enhance process efficiency in HRC. Each single-limb task, composed of basic motion elements identified through Therblig analysis, is assigned to either a human or a robotic agent based on individual capabilities and spatial proximity. The scheme is formulated as a mixed-integer programming problem and solved using a Random-Key Genetic Algorithm. The allocation result is validated through a collaborative assembly process by comparing it with a traditional method that does not differentiate between the hands during task assignment. An augmented reality (AR)-assisted tool is developed to support participants in performing their assigned tasks with enhanced situational awareness during an actual experiment.
