In this paper, we present an approach for the energy-efficiency optimization of a 3-DOF parallel robot. The proposed strategy leverages the task placement, the execution time, and the length of the robot lower arms to minimize the energy consumption for the execution of a predefined high-speed pick-and-place operation. To evaluate the actuators energy consumption, the kinematic, dynamic and electro-mechanic mathematical models, as well as an equivalent multibody model, of the parallel robot are implemented. The results of extensive numerical simulations show that the proposed strategy provides notable improvements in the energy efficiency of the parallel robot, with respect to alternative approaches. Starting from a pick-and-place task with optimal task placement with a consumption of 38.2 J (with a cycle time of 0.4 s), the energy expenditure can be reduced to 3.75 J (with a cycle time of 1.86 s), with a reduction percentage of 90.2%, by additionally optimizing the execution time, and the length of the robot lower arms. These results lead to a reduction from 5733 J/min (for 150 cycles/min) to 121 J/min (for 32 cycles/min), allowing to choose the best trade-off between robot productivity and consumed energy.}, year = {2024}, eissn = {1433-3015}, pages = {1} } @article{MTMT:34781413, title = {Optimization of electric current-assisted sustainable burnishing process of additively manufactured Inconel 718: trade-off between production rate and fatigue life}, url = {https://m2.mtmt.hu/api/publication/34781413}, author = {Alharbi, Naif}, doi = {10.1007/s00170-024-13417-x}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, unique-id = {34781413}, issn = {0268-3768}, year = {2024}, eissn = {1433-3015} } @article{MTMT:34772805, title = {Effects of welding parameters and thermal insulation on the mechanical behavior and microstructure of friction lap-welded aluminum to glass fiber-reinforced thermoset composite with a thermoplastic PA6 interlayer}, url = {https://m2.mtmt.hu/api/publication/34772805}, author = {Sahranavard, Mahdi and Khoramishad, Hadi}, doi = {10.1007/s00170-024-13413-1}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, unique-id = {34772805}, issn = {0268-3768}, abstract = {Friction lap welding was used to join aluminum with glass fiber-reinforced thermoset polymer (GFRP) using a thermoplastic interlayer. The effect of different welding parameters on joint strength and fracture surfaces was investigated, and the optimal welding parameters were determined using the Taguchi method. Results revealed that low heat generation led to weak mechanical interlocking between GFRP and the thermoplastic interlayer, while high heat generation caused degradation of the aluminum/thermoplastic polymer interface. The tool traverse speed was found to be the most influential parameter in terms of joint strength, followed by plunge depth and rotational speed. Moreover, thermal measurements were conducted during the welding process using thermocouples. An uneven thermal distribution was discovered across the overlap area due to dissimilar substrates. This issue was resolved by incorporating aluminum thermal insulation, resulting in improved heat distribution and a significant enhancement of 94% in joint strength. Scanning electron microscopy (SEM) was employed to identify joining mechanisms and examine the effect of welding parameters on joint microstructure. Furthermore, Fourier-transform infrared spectroscopy (FTIR) was used to investigate chemical bond formation at the aluminum/thermoplastic polymer interface. The results showed that the joining mechanisms involved mechanical interlocking between the thermoplastic interlayer and aluminum, as well as chemical bonding, penetration, and intertwining between the thermoplastic interlayer and the thermoset composite.}, keywords = {POLYMER; METAL; FAILURE; Joints; Thermoplastic; Taguchi method; Automation & Control Systems; Al-alloy; Thermosetting; Friction lap welding; Hybrid joint}, year = {2024}, eissn = {1433-3015} } @article{MTMT:34761044, title = {Bibliometric and systematic analysis on electric resistance spot welding of 22MnB5 steel}, url = {https://m2.mtmt.hu/api/publication/34761044}, author = {Ribeiro, Robson Raimundo Cardoso and de Souza, Luiz Gustavo Paes and de Souza Caliari, Juliana Cássia and Teodoro, Claudemiro Luz and de Freitas Gomes, José Henrique}, doi = {10.1007/s00170-024-13487-x}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, volume = {3}, unique-id = {34761044}, issn = {0268-3768}, year = {2024}, eissn = {1433-3015}, pages = {1}, orcid-numbers = {Ribeiro, Robson Raimundo Cardoso/0000-0002-2313-1287; de Souza, Luiz Gustavo Paes/0000-0002-4427-2855; de Souza Caliari, Juliana Cássia/0000-0002-8167-1871; Teodoro, Claudemiro Luz/0000-0003-1777-4291; de Freitas Gomes, José Henrique/0000-0002-7676-554X} } @article{MTMT:34753661, title = {Multimodal perception-fusion-control and human–robot collaboration in manufacturing: a review}, url = {https://m2.mtmt.hu/api/publication/34753661}, author = {Duan, Jianguo and Zhuang, Liwen and Zhang, Qinglei and Zhou, Ying and Qin, Jiyun}, doi = {10.1007/s00170-024-13385-2}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, volume = {IN PRESS}, unique-id = {34753661}, issn = {0268-3768}, year = {2024}, eissn = {1433-3015}, pages = {IN PRESS}, orcid-numbers = {Duan, Jianguo/0000-0003-1548-4637} } @article{MTMT:34747116, title = {Corrosion characteristics of high-entropy alloys prepared by spark plasma sintering}, url = {https://m2.mtmt.hu/api/publication/34747116}, author = {Ujah, Chika Oliver and Kallon, Daramy V.

Corrosion characteristic of HEAs prepared via spark plasma sintering is a top notch as the technique generates corrosion resistant phases and homogenous microstructure. This study was aimed at reviewing recent publications on corrosion characteristics of HEAs processed by SPS in order to develop ways of improving their anti-corrosion properties. The resource materials were obtained from Scopus-indexed journals and Google Scholar websites of peer-reviewed articles published within the last 5 years. From the study, it was revealed that incorporation of some elements (Al, Cr, Ti) into HEAs can improve their corrosion resistance, while addition of some others can reduce their brittleness and enhance their stability and formability. It was recommended that optimization of SPS parameters was one of the strategies of generating better corrosion characteristics in HEAs.}, year = {2024}, eissn = {1433-3015}, pages = {1}, orcid-numbers = {Ujah, Chika Oliver/0000-0002-9713-3023} } @article{MTMT:34740754, title = {Analysis of high temperature and mixed tool wear effects on UD-CFRP cutting mechanism in stacks drilling}, url = {https://m2.mtmt.hu/api/publication/34740754}, author = {Cao, Sipeng and Liu, Ping and Luo, Bin and Rafique, Muhammad Shahbaz}, doi = {10.1007/s00170-024-13285-5}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, unique-id = {34740754}, issn = {0268-3768}, year = {2024}, eissn = {1433-3015} } @article{MTMT:34729219, title = {Influence of cutting tool design on ultrasonic-assisted drilling of fiber metal laminates}, url = {https://m2.mtmt.hu/api/publication/34729219}, author = {Atif, Muhammad and Wang, Xibin and Xie, Lijing and Sun, Ting and Giasin, Khaled and Ma, Yuan}, doi = {10.1007/s00170-024-13128-3}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, unique-id = {34729219}, issn = {0268-3768}, abstract = {Ultrasonic-assisted drilling (UAD) is a machining process that is known to improve the hole quality and reduce cutting forces. Previous studies focused on optimizing cutting parameters to improve the hole quality in conventional drilling (CD) and UAD, as well as to finding the optimum vibration parameters (frequency and amplitude) that will increase the effectiveness of the UAD process. However, the influence of cutting tool type during UAD has been largely overlooked. This research aims to address this gap by analyzing the effect of cutting tool type during UAD on the cutting forces and hole quality in GLARE (Glass Laminate Aluminum-Reinforced Epoxy) laminates. Four types of drills, namely, twist drill (TD), double cone drill (DCD), a step drill type 1 (SD1), and step drill type 2 (SD2) with different step length, were selected for this study. The lowest thrust force (47.04 N) and torque (0.079 Nm) were achieved using twist drill, while DCD, SD1, and SD2 exhibited higher thrust forces (12.81%, 20.69%, 41.3%) and torques (94%, 92%, 91%), respectively. In addition, TD produced high-quality holes with lowest surface roughness (R a 1.66 μm, R z 10.58 μm) and minimal burr formation (entry burr height 152.3 μm, exit burr height 69.22 μm). Conversely, DCD, SD1, and SD2 showed higher surface roughness R a (23%, 16%, 24%) and R z (16%, 37%, 29%), respectively, compared to the TD. Holes drilled using SD1 and SD2 generally had smaller burr height. Overall, UAD system effectively reduced cutting forces at low spindle speed and feed rate. To achieve higher drilling quality, specifically to reduce the surface roughness and exit burr height, a medium spindle speed of 3000 rpm, a feed rate of 225 mm/min is recommended. Drilling at higher cutting parameters using UAD resulted in a decline in hole quality, except for entry burr height.}, year = {2024}, eissn = {1433-3015}, orcid-numbers = {Giasin, Khaled/0000-0002-3992-8602} } @article{MTMT:34724268, title = {A novel chatter detection method in micro-milling process using wavelet packet entropy}, url = {https://m2.mtmt.hu/api/publication/34724268}, author = {Jing, Xiubing and Yang, He and Song, Xiaofei and Chen, Yun and Li, Huaizhong}, doi = {10.1007/s00170-024-13325-0}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, volume = {online first}, unique-id = {34724268}, issn = {0268-3768}, year = {2024}, eissn = {1433-3015}, pages = {1}, orcid-numbers = {Jing, Xiubing/0000-0002-7649-2262} } @article{MTMT:34720231, title = {A seamless CAD/CAM integration approach for venting system generation in injection mold design}, url = {https://m2.mtmt.hu/api/publication/34720231}, author = {Hou, Binkui and Xue, Shuncong and Yang, Jiong and Liu, Deping}, doi = {10.1007/s00170-024-13256-w}, journal-iso = {INT J ADV MANUFACT TECHNOL}, journal = {INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY}, unique-id = {34720231}, issn = {0268-3768}, year = {2024}, eissn = {1433-3015} }
