Traditional sampling-based planning algorithms can find solutions in high-dimensional spaces but often struggle with achieving the balance among computational efficiency, real-time adaptability, and solution optimality. To overcome these challenges and unlock the full potential of robotic automation in smart manufacturing, we propose bidirectional recurrent motion planning network (BRMPNet). As an imitation learning-based approach for robot motion planning, it leverages deep neural networks to learn the heuristics for approximate-optimal path planning. BRMPNet employs the refined PointNet++ network to incorporate raw point-cloud information from depth sensors and generates paths with a bidirectional strategy using long short-term memory (LSTM) network. It can also be integrated with traditional sampling-based planning algorithms, offering theoretical assurance of the probabilistic completeness for solutions. To validate the effectiveness of BRMPNet, we conduct a series of experiments, benchmarking its performance against the state-of-the-art motion planning algorithms. These experiments are specifically designed to simulate common operations encountered within generic robotic platforms in smart manufacturing such as mobile robots and multi-joint robotic arms. The results demonstrate BRMPNet’s superior performance on key metrics including solution quality and computational efficiency, suggesting the promising potential of learning-based planning in addressing complex motion planning challenges.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"13 3","pages":"477 - 492"},"PeriodicalIF":3.8,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145164075","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}

To this end, this study proposes a Blockchain-IPFS (interplanetary file system)-enabled information management platform for improving transparency, traceability, and effectiveness of RMC quality management. Specifically, through a semi-structured interview investigating the potential benefits and applications of Blockchain, a transformative Blockchain-based management mode for RMC quality management is constructed. Based on that, a novel Blockchain-based architecture is further proposed by integrating with IPFS and cloud service for addressing its data storage limitation. Furthermore, the information flows and smart contracts representing physical and cyber interactions among multiple supply chain stakeholders are illustrated in detail. Finally, a real-world case study is presented to verify the feasibility of the proposed model. A prototype system is established with solutions for client-cloud collaboration, multi-source data fusion, and enterprise privacy protection, detailing the practical application of proposed model in actual projects. The evaluation results indicate that the proposed model can improve the quality management of RMC supply chain from three aspects: transparency, traceability, and information sharing. This paper contributes to the body of knowledge by offering a novel architecture leveraging both Blockchain and IPFS in storing small-sized and large-sized information.

Firstly, the combined influence law of strain hardening, strain rate intensification, and thermal softening effects on material removal mechanism was revealed, and models of material removal strain rate, grinding force and grinding temperature were summarized. Secondly, the constitutive models under high strain rate boundaries were summarized by considering various properties of material and grinding parameters. Thirdly, the change law of material removal mechanism of HSG was revealed when the thermodynamic boundary conditions changed, by introducing lubrication conditions such as minimum quantity lubrication (MQL), nano-lubricant minimum quantity lubrication (NMQL) and cryogenic air (CA).

In this study, unidirectional C_f materials were subjected to orthogonal grinding experiments using different fiber orientations. Through a combined analysis of the surface morphology and grinding force after processing, the mechanism underlying the effect of the fiber orientation on the surface morphology of the material was explained. The surface roughness of the material was less affected by the process parameters and fluctuated around the fiber radius scale; the average surface roughness (<i>R</i>_a) in the direction of scratching parallel (SA) and perpendicular (SB) to the fiber direction was 4.21‒5.00 μm and 4.42‒5.26 μm, respectively; the material was mainly removed via the brittle removal mechanism; and the main defects of the fiber in the SA direction were tensile fracture and extrusion fracture; the main defects of the fiber in the SB direction were bending fracture, shear fracture, and fiber debonding. The grinding parameters influenced the grinding force in the order: depth of cut &gt; feed rate &gt; wheel speed. The grinding force increased with an increase in the feed rate or depth of cut and decreased with an increase in the wheel speed. Moreover, increasing the depth of cut was more effective in decreasing the grinding force and improving the material removal efficiency than adjusting the rotational speed of the workpiece and the rotational speed of the grinding wheel.

Besides, a honing experiment is conducted to verify the conclusions. The results at various cutting parameters are analyzed, and the mechanism of burr generation is revealed. The stiffness lacking of the workpiece edge material is the main reason for the burr generation. The cutting depth shows a significant effect on burr size while the cutting speed does not. The inhibition mechanism of ultrasonic vibration on burrs is also revealed. The separation of the burr stress field under ultrasonic vibration and the higher bending hinge point is the reason for burr fracturing.

To ensure optimum gear trans mission performance, the tooth surface texture should be enhanced without comparing the gear precision. By integrating the principle of internal gearing power honing with tooth surface topology modifications, the adjusted honing texture can be forecasted, and proactive control can be achieved, both of which are considered as crucial for the reduction of gear vibration and noise. In this study, a manufacturing technique for high-order modified helical gears is introduced. The formation rules and modeling of the honing texture are explored, leading to a novel method for three-dimensional modeling and control of the altered honing texture. The direction of the cutting speed of abrasive grains at the contact point between the honing wheel and working gear tooth surface was examined. Using the discrete abrasive grain motion trajectory method, the honing texture was produced, through which the formation mechanisms and control strategies of the curved honing texture were illuminated. Based on these findings, a method for flexible topology modifications of the tooth surface is suggested. This is achieved by adjusting the motion coefficients of each axis of the honing machine and adding additional motion in the form of higher-order polynomials to three motion axes, including the radial feed and oscillation axes of the honing wheel and the interleaved axes of the work gear and honing wheel. A least-squares estimation method, based on a sensitivity matrix, was employed to determine the additional motion coefficients. By this method, the texture of the modified tooth surface can also be predicted and controlled. In a numerical example, the efficacy of the flexible topology modification method was confirmed. In this case, the altered honing texture was managed by modifying the axis intersection angle, while the accuracy of tooth surface modifications was maintained.
