Traditional production scheduling and control are increasingly inadequate in light of the rapid evolution of manufacturing technology, the growing impact of unforeseen disruptions, and the generally increasing complexity of production. A framework for future-proof production scheduling and control is introduced to close this gap, providing a comprehensive overview of future requirements and the necessary technologies and approaches. Robust decision criteria are derived, explained and filled with major recent advances in production scheduling and control, digital twins, artificial intelligence, and knowledge formalisation. Emerging trends are discussed, and an outlook for future research and decision-making is derived.

This paper proposes the integration of an electromagnetic field into the ultra-precision grinding process to improve the machinability of the single-crystal nickel-based superalloy. The effects of the magnetic flux intensity on the grinding wheel vibration and surface integrity were investigated through grinding experiments. The results show that the wheel vibration amplitude was reduced by 45.82% by applying the electromagnetic field. The arithmetic mean height (Sa) and the maximum height difference (Sz) were decreased by 71.09% and 67.69%, respectively, in the optimal condition, which demonstrates the effectiveness of the proposed electromagnetic field-assisted ultra-precision grinding process.

The evaluation of chip clogging on the bottom surface of diamond-coated drills is traditionally performed through visual inspection by technicians. This study replicates this sensory evaluation by constructing a clogging discriminator using supervised machine learning with drill surface images. Image features ensuring high discrimination accuracy while minimizing wear or coating influence were identified. Verification results demonstrated that the histogram of oriented gradients and cumulative distribution function of luminance effectively construct a robust clogging discriminator, regardless of surface conditions. This method enables efficient clogging assessment, contributing to practical applications and improved drill performance evaluation in industrial settings.

传统上，技术人员通过目视检查来评估涂金刚石钻头底面的切屑堵塞情况。本研究通过使用有监督的机器学习和钻孔表面图像构建堵塞判别器来复制这种感官评估。图像特征确保高分辨精度，同时最大限度地减少磨损或涂层的影响。验证结果表明，无论表面条件如何，方向梯度直方图和亮度累积分布函数都能有效构建鲁棒的阻塞判别器。该方法能够有效地进行堵塞评估，有助于实际应用，并改善工业环境下的钻井性能评估。

Gallium nitride (GaN) is a promising material for high-power, high-frequency electronic devices. Plasma-assisted polishing (PAP) process achieved high-quality surface polishing of GaN by combining plasma modification with the removal of modified layer using soft abrasives. In PAP, the modification rate directly determines the overall PAP efficiency. This study replaced traditional oxidative plasma with vacuum H₂ plasma, which has a smaller atomic diameter and reducing properties, to improve modification efficiency. By thoroughly investigating the mechanism of H₂ plasma modification on GaN surface and optimizing the relevant process parameters, efficient and controllable GaN surface modification was achieved while suppressing surface roughness deterioration.

氮化镓（GaN）是一种很有前途的高功率、高频电子器件材料。等离子体辅助抛光（PAP）工艺将等离子体修饰与软磨料去除修饰层相结合，实现了高质量的氮化镓表面抛光。在PAP中，改性率直接决定了PAP的整体效率。本研究用原子直径更小、还原性更强的真空h2等离子体取代了传统的氧化等离子体，提高了改性效率。通过深入研究h2等离子体修饰GaN表面的机理，优化相关工艺参数，在抑制表面粗糙度恶化的同时，实现了高效可控的GaN表面修饰。

Gripper systems play a crucial role in robot-based automation. Frequent refitting hinders automation in companies with high product variance, but flexible gripper systems are costly. Therefore, this paper presents a software-based methodology to increase the object flexibility of standardized gripper systems during their design phase. The first step is to use clustering algorithms based on the physical properties of the workpieces to find similarities. Afterward, an optimization is used to identify common grasp points across workpieces. The approach is validated using vacuum gripper systems as a low-cost automation tool and printed circuit board assemblies (PCBAs) as exemplary workpieces.

抓手系统在机器人自动化中起着至关重要的作用。频繁的改装阻碍了产品多样性高的公司的自动化，但灵活的夹具系统是昂贵的。因此，本文提出了一种基于软件的方法来增加标准化夹具系统在其设计阶段的对象灵活性。第一步是使用基于工件物理特性的聚类算法来寻找相似性。然后，采用优化方法确定工件上的共同抓点。采用真空夹持系统作为低成本自动化工具和印刷电路板组件（pcba）作为示例工件验证了该方法。

Freeform optics allow holistic system design in both fields of imaging and illumination. In combination with lens arrays, they enable advanced applications such as aberration free imaging and beam redistribution from multiple irradiation sources. This paper describes an automated design method for freeform optical arrays in both tangential and normal directions. Optimizing the tangential layout of segments increases the solid angle of light collection and thus improves energy efficiency. Surface shapes are then computed by an iterative construction method based on Fermat's principle and Snell's law. Complex illumination with up-to 85% light collection is demonstrated experimentally.

This study explores a large language model (LLM)-based system enhancing design methodology education, focusing on design for environment (DfE). By integrating GPT-4 with DfE guidelines and a dual-loop structured learning workflow, we developed an interactive system addressing persistent challenges in design method learning. Through personalised exercises and systematic feedback, our system guided beginners in applying DfE strategies while fostering self-directed learning. Experiments involving 30 participants revealed significant improvements across Bloom's taxonomy domains, particularly when learners demonstrated sustained or developing proactiveness. This study analysed how LLM-based systems can support education for various design for X methodologies through generalizable interaction frameworks.

Wire Electrical Discharge Machining (Wire EDM) is particularly suitable for producing high-precision geometries in demanding materials such as the manufacture of profile grooves in turbine disks. Advanced monitoring nowadays allows the time and spatially resolved in-process discharge analysis. Therefore, in this paper the machining of Inconel 718 parts is fundamentally studied and the resulting surface integrity in terms of roughness and residual stresses is evaluated for main and trim cut strategies. Finally, the resulting bending fatigue performance is characterized in a zone resolved and overall averaged analysis along the workpiece height and compared to reference results of alternative machining approaches.

线材电火花加工（Wire EDM）特别适合在要求苛刻的材料中生产高精度几何形状，例如涡轮盘的轮廓槽的制造。现在先进的监测允许时间和空间分辨过程中的放电分析。因此，本文对Inconel 718零件的加工进行了基本的研究，并对主要切削策略和切边切削策略的表面粗糙度和残余应力进行了评估。最后，通过区域分解和沿工件高度的整体平均分析来表征弯曲疲劳性能，并与替代加工方法的参考结果进行比较。

Circular economy (CE) strategies hold substantial potential for reducing product carbon footprints (CF), yet their effectiveness and specific impact pathways remain unclear. This study develops a quantitative framework for calculating and comparing the CF under various CE strategies, demonstrated with a case of lithium-ion batteries (LIBs). Results show CE strategies have varying impacts on material and other flows in a battery lifecycle and do not necessarily reduce CF. A combination of six CE strategies halves the CF of LIBs, suggesting additional efforts are required for deeper decarbonisation. This framework offers insights to guide effective CE actions and advance sustainable products.

循环经济（CE）战略在减少产品碳足迹（CF）方面具有巨大潜力，但其有效性和具体影响途径尚不清楚。本研究开发了一个定量框架，用于计算和比较各种CE策略下的CF，并以锂离子电池（lib）为例进行了演示。结果表明，CE策略对电池生命周期中的材料和其他流动有不同的影响，并不一定会降低CF。六种CE策略的组合使lib的CF减半，这表明需要进一步努力实现更深层次的脱碳。该框架为指导有效的CE行动和推进可持续产品提供了见解。

Geometry representation, as a fundamental aspect of topology optimisation, is crucial to meet the growing demand for customised structural designs in Industry 4.0. Implicit neural representation (INR) based on neural network (NN) has emerged as a promising paradigm for geometry representation. To address the limitations of point-wise NN-based INR, this paper proposes a field-wise geometry representation via neural operators on Riemannian manifolds (NORM) for topology optimisation. Verification results demonstrate that the proposed method can not only obtain high-frequency structures with better performance, but also achieve active control of structural frequency and maintain local continuity of the optimised structure.

几何表示作为拓扑优化的一个基本方面，对于满足工业4.0中不断增长的定制结构设计需求至关重要。基于神经网络（NN）的隐式神经表示（INR）已成为一种很有前途的几何表示范式。为了解决基于点向神经网络的INR的局限性，本文提出了一种通过黎曼流形（NORM）上的神经算子进行拓扑优化的场向几何表示。验证结果表明，该方法不仅可以获得性能更好的高频结构，而且可以实现结构频率的主动控制，并保持优化结构的局部连续性。
