While Large Language Models (LLMs) have shown promise in automated MPKB construction, they face a critical challenge in manufacturing: industrial knowledge graph (KG) schemas often exceed the context windows of lightweight LLMs deployable by small and medium-sized enterprises (SMEs). This limitation forces the construction process to operate with incomplete schema information, leading to missed entity relationships, semantic heterogeneity, and conceptual ambiguities in the MPKB. This study proposes an improved LLM-KG collaborative framework that overcomes these limitations through: (1) employing a staged, schema-decoupled extraction strategy, which enables open triple collection without injecting the full schema; (2) introducing a Code-Style knowledge representation method that efficiently encodes complex machining schemas, reducing the semantic load while maintaining structural integrity; and (3) constructing a retrieval-driven pipeline for semantic standardization that integrates dynamic schema segmentation and bidirectional validation, utilizing LLMs to achieve interpretable synonym merging and eliminate heterogeneity. This study empirically validated the proposed approach using machining process data provided by an aviation enterprise. Experimental results demonstrate that our framework achieves at least a 3.3% improvement in MPKB construction quality and a 25% increase in machining process quality metrics compared to the other baseline models.

However, industrial data often exhibit strong spatio-temporal heterogeneity due to the presence of diverse physical measurements and redundant sensor placements, posing significant challenges for effective graph structure learning. Furthermore, when increasing the look-back window length to improve prediction accuracy, the heterogeneity of time series introduces more noise, making it difficult for graph structure learning methods to establish effective edge connections. Meanwhile, homogeneous time series provide redundant spatial features, causing prediction-based graph structure learning methods to fail. This paper is the first to study how to control the learned graph structure density in a multivariate time series prediction model to achieve a reasonable balance between prediction accuracy and structural accuracy. This paper proposes a Spatial Information Bottleneck (SIB) method to simultaneously address the aforementioned two challenges. The SIB method introduces the spatial feature prioritization principle, whereby the prediction model preferentially utilizes neighborhood node features for forecasting in homogeneous time series pairs, thereby enabling graph structure learning to establish connections between homogeneous time series pairs. Second, SIB performs independent information compression on each time series feature, which suppresses prediction-irrelevant noise in heterogeneous time series to varying degrees, thereby mitigating the impact of noise on prediction accuracy under long-sequence inputs. Experiments on industrial process data with accessible ground truth graph structures show that the model based on this method not only enhances prediction accuracy but also generates graph structures that align with physical processes for result interpretation.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"85 ","pages":"Pages 441-454"},"PeriodicalIF":14.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146187919","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}

Second, an explicit analysis method is proposed to distill structured attention cues from unstructured raw visual behavior, providing the critical structured input needed for establishing contextual associations. Finally, to model the expert’s cognitive process, a Visual Chain-of-Thought is introduced, leveraging Large Language Models to establish contextual semantic associations between cues. These chains are then aggregated to construct a hierarchical Context-Aware Cognitive Pathway Graph, completely reconstructing the expert’s cognitive strategy. Quantitative results demonstrate that the proposed method outperforms baseline models, and expert evaluations confirm its exceptional performance in causal validity and diagnostic precision.

System-level optimization, where multiple components are simultaneously optimized, is noted in the literature as a challenging necessity for complete performance improvement of machine tools. Existing methods focus on optimizing the machine tool components individually, neglecting the critical effects of simultaneous modification on the machine performance and thorough exploration of the design space. To the authors’ knowledge, for the first time in the literature, this paper presents a comprehensive framework for system-level machine tool design optimization considering the most significant multi-objective performance indicators for the machining process. Static and dynamic stiffness, thermal and dynamic stability, and fatigue life are evaluated as performance indicators using a multi-objective finite element response set that includes coupled thermal-structural, modal, and frequency response analyses. A minimal parameter set approach is proposed which uses the linear guide joints to minimize the number of design variables, addressing the challenge of increased computational cost in system-level modeling. Machine responses during optimization iterations are predicted by a machine learning model trained on the machine tool’s multi-objective finite element response set, achieving higher accuracy than commonly used polynomial-based methods. A constraint relaxation method is proposed that permits limited degradation relative to the base design, yielding designs that substantially outperform those obtained from unconstrained optimization while avoiding over-constraining. Up to 20 % mass reduction is achieved across the machine tool components while the performance indicators are either improved or maintained with negligible degradation.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"85 ","pages":"Pages 419-440"},"PeriodicalIF":14.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188651","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}
