Overcoming this limitation by amalgamating data from other wind turbines introduces an inherent risk of privacy leakage. To address this issue, we introduced a novel hybrid model for wind power forecasting, specifically designed to address data privacy preservation. This model integrates a temporal convolutional network with a transformer encoder, harnessing the strengths of both components. The temporal convolutional network extracts local temporal patterns, whereas the transformer encoder captures the intricate time dependencies between these patterns. To address the data privacy risks caused by traditional centralized forecasting methods, a federated training strategy is implemented to train a collaborative knowledge-sharing model, ensuring that the original data from the source domains remain confidential and undisclosed. The experimental results validate the effectiveness of the proposed model, showing significant improvements in forecasting performance. When federated with other wind turbines, the average mean absolute error and the root mean square error of six wind turbines are 4.624 6 and 6.245 7, respectively. In contrast to traditional centralized training methods, the proposed federated learning method, which was applied to inland wind turbines, achieved almost no increase in losses.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"14 3","pages":"730 - 746"},"PeriodicalIF":3.9,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148433986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding these interpolation types, four artificial neural network (ANN) models were developed to predict the machining times for each command line in each numerical control (NC) program. Using the proposed data-driven method, the motion type of each command line in the NC program is first identified. The corresponding features are then extracted from the specific command line, which is considered the input of the model, while the estimated machining time is the output. After training and tunning, all four models achieved extremely high prediction accuracies (>95%), which were further validated through cutting experiments. Moreover, the influence of different feedrates on the machining time prediction accuracy in UPM was explored for the first time, demonstrating the excellent robustness of the proposed models at high feedrate compared with the CAM-based method. This strategy is easily applicable to other CNC machine tools, and the compact structure of the ANN model and its low computation consumption enable its deployment in edge devices. With the addition of more datasets, the accuracy and robustness of the proposed model can be further enhanced.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"13 4","pages":"831 - 846"},"PeriodicalIF":3.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145486620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying an external magnetic field, a gradient magnetic field is formed on the surface of the grinding wheel to absorb the magnetic lubricant and improve the infiltration performance. A permanent magnet was used to magnetize the grinding wheel matrix, thereby directing the magnetic flux lines and guiding the distribution of the magnetic field through the grinding wheel.

Grinding force is the most critical parameter reflecting the grinding system, and establishing an accurate prediction model is highly significant in reducing machining damage.

Metallic lattices are the conventional choice for energy absorption, while the generated impact has not been the subject of interest. However, this is the crucial requirement for protective applications like mine-blast absorber for armor vehicles. Different gradient approaches have been examined in this study to find the method which not only controls the absorbed energy, but also keeps the impact level below the identified threshold. This includes available density gradients as well as an innovative gradient geometry for the structure. The concept of how each gradient approach influences the plateau behavior was discussed. A novel approach has been presented which enables tracking the impact magnitude during densification. Although, series density-gradient is a common approach to improve energy absorption in industry, the result of this study demonstrates that crushing the denser region of lattice may generate significantly larger impact. Instead, arranging density gradient cells parallelly can absorb higher energy, while the increase in impact is not significant. An innovative design is presented for lattice structure with gradient geometry. It starts absorbing energy at very low impact and ends with significantly higher absorbed energy at full compaction. To expand the domain of application and effectiveness, new gradient approach was proposed by combining geometry and density grading. It was demonstrated that this highly efficient and flexible design configuration could reduce the activation impact by 94% with descending arrangement and double the absorbed energy by ascending arrangement. This was achieved while the impact magnitude was kept at a reasonable level.
