However, general models may have poor generalization ability and feature interpretability in acoustic emission (high peak, fast attenuation, and long plateau) monitoring tasks. To address this issue, this paper customizes an interpretable model called the contour encoding network tailored to the adaptive cepstrum characteristics of acoustic emission. Specifically, we first analyze the information propagation manner of the acoustic emission adaptive cepstrum within the general model. The paper focuses on extracting valuable discriminative information from the edge contour features of the adaptive cepstrum using learnable high-pass filtering operators. Furthermore, to make the model pay more attention to specific sensitive regions of the input data, this paper proposes a customized attention module. It is non-parameterized, thus having an interpretable computational process. This proposed network architecture can maximize recognition performance, simplify model structure, and improve generalization ability. The effectiveness and reliability of the proposed method are validated on experimental data of laser shock peening. The experimental results demonstrate that the proposed method achieves superior recognition accuracy compared to other advanced networks and exhibits desirable interpretability.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"132 ","pages":"Pages 224-237"},"PeriodicalIF":6.1,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578189","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}

In the horizontal direction, the ice crystals grow stably since the nucleation temperature line is always located at the front end of the ice crystals; thus, a long-range ordered layered morphology is formed on the cross section. Due to the extremely low temperature gradient in the vertical direction, the nucleation temperature line exceeds the front end of the ice crystal growth, resulting in the simultaneous nucleation and growth of multiple ice crystals and the formation of a dendritic lamellar morphology on the longitudinal section. In addition, due to the increase of undercooling and the settlement of ceramic particles, the ceramic content increases gradually from the upper to the lower part of the ceramic skeleton, while the layer thickness and pore width decrease accordingly. Subsequently, AZ91 is filled into the Ti(C, N) skeleton via gas pressure infiltration to obtain Ti(C, N)/AZ91 layered composites. Due to the strong support provided by the bottom-up continuous ceramic layer, the lower part of the composites has the highest compressive strength (395 MPa), while their middle part exhibits the best fracture initiation toughness (14.2 MPa·m<sup>1/2</sup>), crack propagation toughness (32.6 MPa·m<sup>1/2</sup>), and bending strength (421 MPa). The high strength and toughness in the middle portion of the composites can be attributed to the fewer defects in the ceramic layer, the plastic deformation of the metal layer, and a variety of external toughening mechanisms. Due to the combined effect of various non-inherent toughening mechanisms, the R curve of the composites presents an upward behavior, i.e., the fracture resistance is improved during the fracture process.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"132 ","pages":"Pages 130-141"},"PeriodicalIF":6.1,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572753","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}

The trajectories generated by most robotic grinding trajectory planning algorithms are often found to be inferior in grinding large compound surface workpieces, as they are typically designed for robotic machining with a fixed base. In this paper, a novel iso-planar algorithm based on oriented bounding box (OBB) of the workpiece is developed to plan the grinding trajectories by taking into consideration the characteristics of blade. The constant chord length algorithm employing Taylor quadratic expansion is then developed to discretize trajectory into grinding points. Considering the characteristics of compound surface, a post-processing strategy is proposed to eliminate redundant grinding points and generate consistent tool orientations on compound surface. Based on these three steps, a workstation location optimization model for improving robot manipulability is introduced to determine a series of workstation locations. Furthermore, the grinding and movement synchronization strategy based on mobile platform trajectory interpolation is proposed to enhance the efficiency of machining large workpieces.
