In machining, high temperatures and strain rates impact the flow stress of the workpiece material, making it essential to understand the materials behaviour in these process conditions for meaningful finite element analysis (FEA) of the cutting process. The Johnson-Cook constitutive model, despite being the most widely applied, is reported to struggle in capturing the material behaviour outside of the reference conditions it was calibrated on. However determining these parameters in conventional material tests is challenging. To solve this issue, this study proposes a grey-box approach which aims to increase the accuracy of process force prediction of FEA, employing a Johnson-Cook model determined by experiments conducted on a Split-Hopkins Pressure Bar and compression tests at elevated temperatures on a Gleeble 3800c for AISI 1045, over a variety of cutting parameters. In total 110 cutting experiments and their corresponding simulations were carried out in a fully factorial experimental design with eleven cutting speeds and ten uncut chip thicknesses. Succeeding the white-box model, a black box model is trained to capture the non-linear behaviour between the simulation and the cutting experiments. Among the tested algorithms, XGBoost and Support Vector Regression outperformed Random Forests and Neural Network for predicting cutting force and feed force. The proposed grey-box approach showed an improved capability of predicting cutting force and feed force, reducing the mean absolute error and mean squared error compared to the white-box model by 97.9 % and 99.9 % for cutting force and by 94.9 % and 99.7 % for feed force, respectively. The grey-box model achieved a mean error of 1.3 % with a standard deviation of 0.1 in process force prediction.

在机械加工中，高温和应变率会影响工件材料的流动应力，因此了解这些工艺条件下的材料行为对于切削过程的有意义的有限元分析（FEA）至关重要。Johnson-Cook本构模型尽管应用最为广泛，但据报道，它难以捕捉其校准的参考条件之外的材料行为。然而，在常规材料测试中确定这些参数是具有挑战性的。为了解决这一问题，本研究提出了一种灰盒方法，旨在提高有限元分析过程力预测的准确性，采用Johnson-Cook模型，该模型是通过在Split-Hopkins压力棒上进行的实验和在Gleeble 3800℃的AISI 1045上进行的高温压缩试验确定的。在全析因试验设计中，共进行了110次切削实验并进行了相应的仿真，实验设计有11种切削速度和10种未切削切屑厚度。在白盒模型之后，训练了一个黑盒模型来捕捉仿真和切割实验之间的非线性行为。在测试算法中，XGBoost和支持向量回归在预测切削力和进给力方面优于随机森林和神经网络。提出的灰盒方法预测切削力和进给力的能力有所提高，与白盒模型相比，切削力的平均绝对误差和均方误差分别降低了97.9% %和99.9 %，进给力的平均绝对误差和均方误差分别降低了94.9% %和99.7 %。灰盒模型在工艺力预测中的平均误差为1.3 %，标准差为0.1。

Indexable insert drills play a crucial role in high-performance drilling, particularly for large-diameter holes and difficult-to-machine materials. Although FEM is a powerful tool for analyzing and optimizing drilling processes, limited research has focused on indexable insert drills, and the efficient simulation of large-diameter drills with complex cutting geometries remains a significant challenge. This study presents an optimized and computationally efficient FEM model for indexable insert drills, developed in AdvantEdge™ 3D, capable of predicting thermomechanical loads (thrust force, torque, stress, temperature) and chip morphology during drilling and redrilling of AISI 316 L stainless steel. The key innovation lies in a computational approach that significantly reduces simulation time while maintaining high predictive accuracy. The model incorporates a novel tool–workpiece configuration with a slotted workpiece that enables the drill to reach nominal feed rate immediately upon engagement, accelerating convergence toward thermomechanical steady-state. Model optimization was achieved through a systematic evaluation of the most influential input parameters, surpassing the capabilities of previous FEM approaches and providing new validated insight into drilling process modeling. A comprehensive sensitivity analysis of Johnson–Cook flow stress parameters, friction coefficients, and mesh size was performed to optimize both accuracy and computational efficiency. The model was experimentally validated through complete-drill tests (both inserts mounted) and novel single-insert tests (one insert mounted) across a wide range of cutting conditions, including redrilling with varying pilot hole diameters. The optimized model accurately predicts torque, thrust forces, and chip morphology (average error: 16 %), while providing detailed stress and temperature distributions. Thrust force underprediction remains the primary limitation, identified as originating from the central insert, where Build-Up Edge (BUE) formation was observed at low cutting speeds near the drill tip.

可转位镶钻在高性能钻孔中发挥着至关重要的作用，特别是对于大直径孔和难以加工的材料。虽然有限元分析是分析和优化钻孔工艺的有力工具，但有限的研究集中在可转位镶齿钻头上，并且具有复杂切削几何形状的大直径钻头的有效模拟仍然是一个重大挑战。本研究提出了一个优化的、计算效率高的可转位嵌套钻头有限元模型，该模型是在AdvantEdge™3D中开发的，能够预测AISI 316 L不锈钢在钻削和再钻削过程中的热机械载荷（推力、扭矩、应力、温度）和切屑形态。关键的创新在于一种计算方法，可以在保持高预测精度的同时显着减少模拟时间。该模型结合了一种新颖的工具-工件配置，具有开槽工件，使钻头在啮合后立即达到标称进给速率，加速了向热机械稳态的收敛。通过对最具影响力的输入参数进行系统评估，实现了模型优化，超越了之前FEM方法的能力，并为钻井过程建模提供了新的验证见解。对Johnson-Cook流动应力参数、摩擦系数和网格尺寸进行了综合敏感性分析，以优化精度和计算效率。该模型通过全钻测试（安装了两个钻头）和新型单钻头测试（安装了一个钻头）在各种切削条件下进行了实验验证，包括在不同的导孔直径下进行重钻。优化后的模型准确地预测了扭矩、推力和芯片形态（平均误差：16 %），同时提供了详细的应力和温度分布。推力预测不足仍然是主要的限制因素，主要原因是中心镶齿，在钻头尖端附近低切削速度下观察到积聚边缘（BUE）地层。

To address the limitations in accuracy and interpretability of milling force prediction, this research proposes HyDCFF-Net, an interpretable model integrating physical time-frequency features with deep learning. First, vibration signals are processed using sliding windows, and a dual-channel neural network is developed to fuse these features, establishing a robust nonlinear mapping to milling force. Next, the Captum framework provides interpretability by visualizing feature contributions. Finally, extensive experiments under varied conditions validate its high prediction accuracy and strong generalization, achieving R² scores above 0.98 on primary tests with robust cross-dataset performance, demonstrating its effectiveness as a reliable milling force monitoring solution.

Solid-state deposition is one of the promising research areas. Here, the material does not melt during the process; instead, the material is plasticized to achieve the desired deformation. The present work employs friction stir metal deposition to create a three-dimensional wall structure of Inconel 600 through layer-by-layer deposition. A defect-free, fully consolidated wall without visible voids was deposited with more than 100 layers. The deposition was performed at 2500 RPM, with a 5 mm/min plunge feed and a 220 mm/min forward feed rate. The layer thickness was found to be decreasing in the build direction. Thermal history showed that layer deposition reheats the substrate and previously deposited layers. The temperature in the deposited wall varies in deposition and build direction. The heating-cooling cycle at the ends of the deposit is very different from the remaining portion of the deposit. Ends are exposed to higher temperatures for relatively shorter periods and once in every layer of deposition. In contrast, the remaining deposition is exposed to higher temperatures for a more extended period and twice in one layer of deposition. Also, a tool with an associated flash (Tool-flash) affects the heating of layers. The tool-flash's leading edge has a lower temperature than the tool flash's trailing edge, and the material beneath the tool-flash is heated cyclically. Microstructural investigation explained the effect of this non-uniformity of temperature in the grain morphology. Electron back scattered diffraction (EBSD) showed dynamic recrystallization-driven grain refinement where the grain size of the base material was 16–22μm, which changed to a final grain size of 8.3μm after FSMD. Further investigation along the build direction showed a trend of increasing grain size from the bottom towards the top with some alternate bands of fine grain region near the interface. Grains near the interface were as small as 0.1 μm. Electron backscattered diffraction (EBSD) results also showed that most of the grains were equiaxed with the presence of twin boundaries. Microhardness measurement showed decreasing trend along build direction, which is inline with the grain morphology and Hall Petch’s relationship. The tensile strength of deposition in the longitudinal direction showed comparable mechanical properties with the base material with a deposition efficiency of 78.3 %. Fractography of the failed samples showed ductile fracture with the significant presence of dimples and some parabolic dimples due to some delamination of layers. Energy dispersive spectroscopy results showed no elemental segregation, which was confirmed with uniform element distribution on the fracture surface.

固态沉积是一个很有前途的研究领域。在这里，材料在加工过程中不会熔化；相反，材料被塑化以达到所需的变形。本研究采用摩擦搅拌金属沉积法，逐层沉积，形成了英科乃尔600的三维壁面结构。一个无缺陷、完全固结、没有可见空隙的墙体被沉积了100多层。沉积的转速为2500 RPM，进料速度为5 mm/min，进料速度为220 mm/min。层厚在构建方向呈减小趋势。热历史表明，层沉积使基底和先前沉积的层重新加热。沉积壁内的温度随沉积和构筑方向的不同而变化。沉积物末端的加热-冷却循环与沉积物的其余部分非常不同。在每一层沉积中，末端暴露在较高温度下的时间相对较短。相比之下，剩余的沉积在更高的温度下暴露更长的时间，在一层沉积中暴露两次。此外，带有相关闪光（tool -flash）的工具会影响层的加热。工具闪片前缘的温度低于工具闪片后缘的温度，并且工具闪片下方的材料被循环加热。显微组织研究解释了这种温度不均匀性对晶粒形貌的影响。电子背散射衍射（EBSD）显示出再结晶驱动的晶粒细化过程，基材的晶粒尺寸为16 ~ 22μm， FSMD后最终晶粒尺寸为8.3μm。进一步研究表明，沿构筑方向晶粒尺寸呈自下而上增大的趋势，在界面附近有一些细晶粒区域的交替带。界面附近晶粒小至0.1 μm。电子背散射衍射（EBSD）结果也表明，大多数晶粒是等轴的，存在孪晶界。显微硬度测量结果显示，沿铸模方向呈下降趋势，这与晶粒形貌和霍尔-佩奇关系一致。沉积的纵向抗拉强度与基材相当，沉积效率为78.3% %。失效试样的断口形貌显示韧性断裂，由于层的分层，存在明显的韧窝和一些抛物型韧窝。能量色散分析结果表明，断口表面元素分布均匀，没有元素偏析。

The ability to undergo complex forming operations without failure due to necking or cracking is an essential feature for automotive sheet material. The present study examines the effects of chemical composition and processing parameters on the mechanical properties of industrial 6016 aluminium sheets. The homogenization process and the Mn content were used to investigate the influence of dispersoids. Moreover, the solution treatment, the Si content and the use of recycling-friendly compositions were studied. A (semi-)industrial scale deep drawing tool with a fixed drawing depth and varying blank holder force was used to characterize the formability of the sheets at different drawing speeds. An analysis of the strain hardening behaviour via Kocks-Mecking plots revealed remarkable predictive power, enabling the estimation of the behaviour under complex sheet forming conditions from tensile testing. Microstructural investigations demonstrated that dispersoids or constituent particles exerted a minimal influence on strain hardening at high degrees of deformation, whereas dissolved Si exerted a significant influence, resulting in markedly enhanced forming performance. This is linked to the suppression of dynamic recovery, which in turn leads to the interesting results that an alloy produced with higher recycled content performed very well.

能够经受复杂的成形操作而不因颈缩或开裂而失效是汽车板材材料的基本特征。本研究考察了化学成分和加工参数对工业6016铝板机械性能的影响。采用均质化工艺和Mn含量考察了分散体的影响。此外，还研究了固溶处理、硅含量和循环友好型成分的使用。采用固定拉深和不同压边力的（半）工业规模拉深工具，对不同拉深速度下板材的成形性能进行了表征。通过Kocks-Mecking图分析应变硬化行为显示出显著的预测能力，可以通过拉伸测试估计复杂板料成形条件下的行为。显微组织研究表明，在高度变形时，分散体或组成颗粒对应变硬化的影响很小，而溶解的Si对应变硬化的影响很大，从而显著提高了成形性能。这与动态恢复的抑制有关，这反过来又导致了有趣的结果，即具有较高回收含量的合金性能非常好。

As a super - hard material, cemented carbide has high hardness and low fracture toughness. When processed using traditional methods, it is characterized by low efficiency, high cost, and poor quality. This paper proposes a laser - ultrasonic composite milling (LUCM) machining process to improve the ultra - precision machining performance of cemented carbide. The motion characteristics of ultrasonic vibration and the characteristics of laser preheating were analyzed, and a theoretical milling force model was established, with prediction results having an error of less than 10 %. Compared to conventional milling (CM), ultrasonic assisted milling (UAM), and laser assisted milling (LAM), the main milling force (Fx), radial force (Fy), and axial force (Fz) values of LUCM were reduced by 23.49 % – 58.50 %, 6.90 % – 39.79 %, and 13.07 % – 29.44 %, respectively. Tool life was extended by 91.63 %, 44.65 %, and 29.46 %, respectively, and surface roughness was reduced by up to 33.05 %. According to the response surface method (RSM) analysis, when the laser power (LP) was 345.775 W, the laser beam diameter (LBD) was 0.236 mm, the distance from laser spot center (DFLSC) was 0.059 mm, and the ultrasonic amplitude (UA) was 2.065μm, the minimum value of the optimized Fx was 70.452 N. In addition, the experimental data were fitted and trained using an artificial neural network (ANN), and the results showed that the experimental and fitted values were highly consistent, with an error of less than ± 2.

Tool life was extended by 91.63 %, 44.65 %, and 29.46 %, respectively, and surface roughness was reduced by up to 33.05 %. According to the response surface method (RSM) analysis, when the laser power (LP) was 345.775 W, the laser beam diameter (LBD) was 0.236 mm, the distance from laser spot center (DFLSC) was 0.059 mm, and the ultrasonic amplitude (UA) was 2.065μm, the minimum value of the optimized <em>Fx</em> was 70.452 N.

In burnishing process, due to local deformation and ball rolling, material is subjected to complex stress state and different stress components are applied to the workpiece. Under these loading conditions, material enters the plastic zone and accumulation of plastic strain leads to the development of damage within the workpiece. Damage prediction in multi-stage processes is challenging. In this work, modeling of process was performed using finite element (FE) method and contact mechanics theory. Little research has been done on the mechanism of damage accumulation in burnishing, so the aim of this work is to investigate the process mechanics and damage prediction using a nonlinear model. The damage model was defined by the VUSDFLD subroutine in Abaqus software. The effect of reverse loading on damage growth and the accuracy of predicting failure onset was investigated. Deformation mechanics indicate severe changes in the stress state, which should be considered in the calibration of damage criterion. Therefore, the nonlinear model was calibrated by a new test appropriate to the loading in burnishing. According to the results, using the nonlinear criterion and choosing the damage formation threshold of

, the critical penetration depth was predicted with an error of 4.54 %. The effect of threshold value on the moment and location of failure initiation is significant, such that its non-definition led to an error of 36.4 % in predicting the critical penetration depth. Plastic strain was used to estimate the work hardening. The variations in plastic strain along the thickness correspond to hardness distribution in workpiece.

在抛光过程中，由于局部变形和球滚，材料处于复杂的应力状态，工件受到不同的应力分量。在这些加载条件下，材料进入塑性区，塑性应变的积累导致工件内部损伤的发展。多阶段过程的损伤预测具有一定的挑战性。本文采用有限元法和接触力学理论对过程进行了建模。由于目前国内外对抛光过程中损伤积累机理的研究较少，本文拟采用非线性模型研究抛光过程中的损伤积累机理和损伤预测。利用Abaqus软件中的VUSDFLD子程序定义损伤模型。研究了反向加载对损伤扩展的影响以及预测失效发生的准确性。变形力学表明应力状态发生了剧烈变化，这在损伤准则的定标中应予以考虑。因此，采用一种适合于抛光载荷的新试验对非线性模型进行校正。结果表明，采用非线性准则，选择损伤形成阈值为- 23，预测临界侵彻深度，误差为4.54%。阈值对起裂力矩和起裂位置的影响显著，其不明确导致临界侵彻深度预测误差达36.4%。用塑性应变来估计加工硬化。塑性应变沿厚度方向的变化与工件的硬度分布相对应。

Friction Stir Welding (FSW) is increasingly adopted by industry to join difficult-to-weld materials thanks to its high energy efficiency and environmental sustainability. However, despite the extensive research, the studies on the sustainability of the process in correlation with the mechanical performance of the joints are still in the early stages. This study combines the analysis of energy consumption and mechanical properties in the FSW of dissimilar aluminum alloys, exploring different combinations of key process parameters. A gate-to-gate Life Cycle Assessment (LCA) was conducted to evaluate the environmental impact of the FSW process. From a sustainability standpoint, the optimal result was achieved using the highest travel speed (TS) of 270 mm/min in combination with a tool rotational speed (TRS) of 2000 rpm. Under these process conditions, reductions of up to 61 % in global warming potential (GWP), 62 % in total energy consumption, and 62 % in specific welding energy (SWE) were observed at the cost of approximately a 13 % reduction in flexural strength. As a result, power/energy, microhardness, microstructure, and flexural tests were incorporated into welding parameter maps to help in identifying minimum energy consumption and GWP points within the process constraints needed for maintaining good welding quality.

搅拌摩擦焊（FSW）由于其高能效和环境可持续性，越来越多地被工业应用于连接难焊材料。然而，尽管研究广泛，但对该过程的可持续性与节点力学性能的关系的研究仍处于早期阶段。本研究结合对不同铝合金搅拌搅拌能耗和力学性能的分析，探索关键工艺参数的不同组合。通过“门到门”生命周期评估（LCA）来评估FSW过程的环境影响。从可持续性的角度来看，当最高行程速度（TS）为270 mm/min，刀具转速（TRS）为2000 rpm时，获得了最佳结果。在这些工艺条件下，全球变暖潜能值（GWP）降低了61% %，总能耗降低了62% %，比焊接能量（SWE）降低了62% %，而弯曲强度降低了约13% %。因此，功率/能量、显微硬度、微观结构和弯曲测试被纳入焊接参数图，以帮助确定在保持良好焊接质量所需的工艺限制内的最小能耗和GWP点。

Driven by the need to respond effectively to the dynamic demands of globalized markets, industrial organizations are continuously improving their manufacturing processes. In this context, manufacturing systems require flexible workpiece fixturing devices that ensure both effective and efficient operational repeatability to accommodate the growing trend of mass customization. This paper presents an innovative solution to meet the requirements of a self-adjusting fixturing system characterized by functional independence, defined here as the decoupling of key operations (such as thickness adjustment and clamping force) to enhance control and performance. To achieve this, the proposed approach integrates several theories and tools, including mechanism theory, graph theory, axiomatic design, and ergonomics. The result is a functional prototype that demonstrates the strengths of the proposed design approach in defining solutions with complex topologies for workpiece fixturing applications. This novel design offers significant practical benefits, including drastically reduced setup times and a pre-settable, independent clamping force. The methodology and resulting system provide a robust solution for flexible manufacturing, particularly in mass customization and future automated (Industry 4.0) environments.

To effectively control the springback of agricultural tractor mudguards, this paper proposes an optimized design framework for springback control. The framework centers on stress path control and geometric reverse compensation, integrating process parameter optimization, theoretical modeling, auxiliary structure design, and geometric reverse mold compensation. This approach transitions from a single-method strategy to a combined approach of “process parameter control – drawbead setting – geometric reverse compensation”. The results indicate a significant correlation between the thickness, blank holder force, stamping speed, friction coefficient, and die clearance with the springback amount. The semi-analytical model and response surface model developed have coefficients of determination of 0.921 and 0.917, respectively. A complex non-linear relationship exists between each parameter and the springback, with distinct mathematical variation curves observed. The primary and secondary effects of the parameters are ranked as follows: blank holder force, die clearance, thickness, friction coefficient, and stamping speed. By employing the “process parameter control – drawbead setting – geometric reverse compensation” strategy, the springback can be controlled to 5.37 °. Moreover, experimental validation yields a springback of 5.14 °, which results in a 0.23 °. This study provides a solid theoretical foundation and reliable numerical basis for the practical production and processing of mudguards.

为了有效控制农用拖拉机挡泥板的回弹，提出了一种优化的回弹控制设计框架。该框架以应力路径控制和几何反向补偿为核心，集工艺参数优化、理论建模、辅助结构设计和几何反向补偿于一体。该方法由单一方法转变为“工艺参数控制-拉延头设定-几何反向补偿”的组合方法。结果表明，厚度、压边力、冲压速度、摩擦系数和模具间隙与回弹量有显著的相关性。建立的半解析模型和响应面模型的决定系数分别为0.921和0.917。各参数与回弹之间存在复杂的非线性关系，具有明显的数学变化曲线。各参数对压边力、模具间隙、厚度、摩擦系数、冲压速度的主要影响和次要影响依次为：压边力、模具间隙、冲压速度。采用“工艺参数控制-拉延头设定-几何反向补偿”策略，可将回弹控制在5.37°。此外，实验验证产生5.14°的回弹，其结果为0.23°。该研究为挡泥板的实际生产加工提供了坚实的理论基础和可靠的数值依据。
