480. Multi-axis ball-end milling force prediction model considering the influence of cutting edge.

Abstract

Precise prediction of milling force is a crucial issue in multi-axis milling, which is important for evaluating the tool life and surface quality. In this paper, an improved force model for ball-end milling is proposed based on a novel uncut chip thickness (UCT) model as well as the consideration of edge effect and size effect. The computational model of UCT takes into account the influence of lead and tilt angles in ball-end milling. In addition, it utilizes a new discretization method of the uncut chip area that ensures the local cutting edge is perpendicular to the length of the elemental uncut chip area, making it more compatible with the classical oblique cutting model. For each elemental cutting edge, the force components are calculated through a purely analytical approach, considering the shear force, edge force, and size effect caused by cutting edge geometry in milling process. The proposed model is comprehensively validated with both FEM and multi-axis milling experiments for aluminum and titanium. The results indicate that the proposed model can predict the dynamic milling force under various cutting conditions in a good manner. Moreover, considering edge and size effects can further improve the prediction accuracy. [ABSTRACT FROM AUTHOR]

Abstract

Liu, J.; Xing, L.; Shao, C.; Li, S.; Huang, M.; Weng, J., and Fu, C., 2023. Update to the Quaternary stratigraphic division in Xiaoshao Plain, Zhejiang, China. Journal of Coastal Research, 39(5), 984–997. Charlotte (North Carolina), ISSN 0749-0208. Establishing a reliable chronological framework of Quaternary sedimentary stratigraphy contributes to a more comprehensive understanding of the evolutionary patterns of sedimentary environments and predicts their trends. Local exploration standards are essential indicators in the construction of a chronological framework for Quaternary sedimentary stratigraphy. However, many of the local standards introduced today lack detailed field investigations and comprehensive and in-depth analyses of geological investigations in local areas and still need further improvement. For these areas, there are significant differences in understanding between different researchers, and the absence of appropriate and uniform local standards will lead to misjudgment of geological conditions and cause much inconvenience in the design, construction, and management of engineering and construction projects. On the basis of this, Xiaoshao Plain in Zhejiang Province, China serves as a research subject and samples were collected by drilling and coring. The Quaternary stratigraphy of Xiaoshao Plain is tentatively divided into nine major layers and 22 sublayers following the local standard of Zhejiang Province's Code for Geotechnical Engineering Investigation of Engineering Construction (DB33/1065-2009) introduced in 2009. The geological age of some of the strata in the area and changes in the depositional environment were further explored through accelerator mass spectrometry (AMS) 14C testing and microsomal paleontological fossil identification. Thus, the large stratigraphy of the Quaternary sedimentary strata of Xiaoshao Plain in the Zhejiang local standard is supplemented. Finally, in combination with the existing regional engineering geological survey report, the stratigraphic substratum of the area has been reclassified (the study divides it into 36 substrata). This study provides new ideas for the improvement of local standards for geological surveys and guidance for engineering construction development in Xiaoshao Plain. [ABSTRACT FROM AUTHOR]

486. Dynamic Moore–Penrose Inversion With Unknown Derivatives: Gradient Neural Network Approach

Author

Zhang, Yinyan, Zhang, Jilian, and Weng, Jian

Abstract

Finding dynamic Moore–Penrose inverses (DMPIs) in real-time is a challenging problem due to the time-varying nature of the inverse. Traditional numerical methods for static Moore–Penrose inverse are not efficient for calculating DMPIs and are restricted by serial processing. The current state-of-the-art method for finding DMPIs is called the zeroing neural network (ZNN) method, which requires that the time derivative of the associated matrix is available all the time during the solution process. However, in practice, the time derivative of the associated dynamic matrix may not be available in a real-time manner or be subject to noises caused by differentiators. In this article, we propose a novel gradient-based neural network (GNN) method for computing DMPIs, which does not need the time derivative of the associated dynamic matrix. In particular, the neural state matrix of the proposed GNN converges to the theoretical DMPI in finite time. The finite-time convergence is kept by simply setting a large parameter when there are additive noises in the implementation of the GNN model. Simulation results demonstrate the efficacy and superiority of the proposed GNN method.

487. TAGKA: Threshold Authenticated Group Key Agreement Protocol Against Member Disconnect for UANET

Author

Zhang, Zhan, Li, Xinghua, Wang, Yunwei, Miao, Yinbin, Liu, Ximeng, Weng, Jian, and Deng, Robert H.

Abstract

The development of unmanned aerial vehicle (UAV) technology has been advancing rapidly and is widely applied in various domains. Compared to a single UAV, the multi-UAV system, known as the UAV Ad Hoc Network (UANET), can collaborate to accomplish complex tasks more efficiently. Due to the UAVs communicating through open wireless channels, they are vulnerable to various attacks. Group key agreement protocols are often used to guarantee the security of UANET communication. However, the high dynamics of UAVs and the instability of the wireless links often result in certain UAVs temporarily losing connection with the group, rendering them incapable of participating in the group key agreement process. Regrettably, existing literature on group key agreement does not consider this issue, which makes them not applicable to UANET. To address this issue, we propose a threshold authenticated group key agreement protocol (TAGKA) that can resist the disconnection of group members. Then, considering that the temporarily disconnected UAVs need to obtain the latest group key after the communication links are recovered, we design a group key recovery protocol. The security of the scheme is proved under the random oracle model. Moreover, formal security verification using the Tamarin and rigorous informal security analysis is also performed. Finally, we use NS-3 to simulate the protocol, and the experimental results show that our protocol can be effectively applied to UANET.
