In the multi-variety and low-volume electroplating production, it is known that the task loading sequence and hoist scheduling are coupled with each other, and they codetermine the production efficiency, while all the existing scheduling methods consider them separately, and thus the optimal production schemes become unavailable. Therefore, this paper develops a Task sequence-Hoist scheduling Coupled Optimization (THCO) model which simultaneously considers the requirements and practical constrains of task sequence and hoist scheduling, having an optimization objective of minimizing the maximum completion time. For this model, a double-layer code is developed and an Improved Salp Swarm Algorithm (ISSA) is developed by introducing three improvement strategies: the random spare strategy which is used to increase the population diversity, the nonlinear adaptive weight strategy which is used to balance the exploration and exploitation capacities, and a golden sine algorithm which is used to improve the convergence rate. Experiments based on 23 benchmark functions are then conducted. The obtained results show that ISSA has better convergence and solving quality than existing algorithms. Furthermore, several production cases prove that THCO can generate production schemes that better meet the requirements of production lines.</p></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"53 ","pages":"Pages 34-47"},"PeriodicalIF":4.6,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141607968","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}

However, the stiffness of robots is significantly lower than that of machine tools, and they are more prone to chattering. Compared to machine tools, robots mainly occur mode coupling chatter. Analyzing chatter in robots is a great challenge due to the highly flexible and pose-dependent position of the robotic arm. Mode coupling chatter is caused by the most flexible and dominant structural modes of the robot milling system. Available methods are unable to identify the structural modal parameters of a milling robot at all poses in the actual working state. This paper proposes a modal analysis method for robots, which can realize the automatic traversal of the pose of the milling robot and the automatic identification of modal parameters. This paper analyzes the robot multi-joint flexibility characteristics, spatial structure characteristics, and machining vibration characteristics, correlates the joint motor control system and current power characteristics, finds the correlation between the current information and the vibration information, and identifies the modal frequency through the current signals, and realizes the modal frequency identification in the entire workspace. This method is capable of output-only complete mode shape identification, can quickly analyze the main vibration modes, and is of great significance for the study of robot milling chattering.</p></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"53 ","pages":"Pages 48-66"},"PeriodicalIF":4.6,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141607969","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}

In this study, the bimetallic wall of aluminium alloys (ER5356/ER4043) is fabricated by cold metal transfer based WAAM technique using two deposition directions (unidirectional and bidirectional) and three current combinations (115 A/90 A, 120 A/95 A, 125 A/100 A). The effect of deposition direction and current on microstructure evolution, mechanical properties, and residual stress has been investigated. Experimental results displayed better properties in bi-directional wall build at a current combination of 115 A/90 A. This is confirmed by optical microstructure as well as field emission scanning electron microscopy, which shows equiaxed grains on the ER4043 layer, fine grains on the ER5356 layer, and columnar-fine grains at the interface of the bi-directional wall while discontinuous dendritic grains is displayed in ER5356 layer of unidirectional wall. Energy dispersive spectroscopy analysis indicates a main difference in weight percentage for Si and Mg contents at the interface layer of the bidirectional wall than the unidirectional wall, with X-ray diffraction analysis specifying the intermetallic compounds like α-Al, Al₁₂Mg₁₇, Mg₂Si, AlMg, and Al_3.21Si_0.47 in both depositional directions. Tensile strength at the interface layer of the bi-directional wall surpasses the tensile strength of the unidirectional wall's interface layer, with fracture morphology indicating ductile fracture in all specimens. The microhardness test reveals an increase in hardness in the transverse direction at the current combination of 115 A/90 A and also in the bidirectional deposition wall compared to the unidirectional wall. Bidirectional deposition has generated less residual stress than unidirectional walls.</p></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"53 ","pages":"Pages 17-33"},"PeriodicalIF":4.6,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141594543","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}

Among the prevalent post-processing techniques, the acoustic cavitation-based surface finishing technique has recently emerged. Despite a considerable amount of focused research on the material removal mechanisms of this technique, less attention has been devoted to addressing its limitations associated with enhancing the process capability towards achieving a better surface finish. The driving force behind the acoustic cavitation technique is the bubble implosion through cavitation streaming, and the cessation of the acoustic cavitation streaming beyond a certain length is the main limitation. It has restrained the process capability towards finishing both external and internal surfaces. Hence, this research aims to unravel novel ways of employing the acoustic cavitation-generating parameters and achieving better-quality surface finishing of additively manufactured (AM) components. A study has been conducted on different AM materials, including Inconel 625 and aluminum alloy, by introducing various methods associated with acoustic amplitude, working mediums, temperature, and external vibration. The results reveal a significant reduction in average surface roughness for both materials. The topographical and morphological observations confirm the qualitative improvement on the surfaces. In addition, the conical bubble structures that frame the acoustic cavitation streaming are elucidated by implementing high-speed imaging techniques, and their enhancement at different parametric conditions is delineated. Henceforth, the findings suggest a notable insight into the potential of the employed approaches in enhancing the acoustic cavitation streaming for achieving a better surface finish of AM components.</p></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"53 ","pages":"Pages 1-16"},"PeriodicalIF":4.6,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141594542","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}
