Data scarcity remains a major barrier to the effective deployment of AI in manufacturing, where labeled data is often limited, costly, or difficult to obtain. This review investigates how synthetic data generation techniques are being applied to address this challenge in manufacturing AI applications. Eighteen recent papers (Jan 2024- May 2025) were analyzed and categorized based on generation methods, application domains, and data modalities. Techniques covered include GAN (Generative Adversarial Networks), VAEs (Variational Autoencoders), diffusion models, simulation-based approaches, SMOTE (Synthetic Minority Oversampling Technique), and hybrid combinations. Their use spans tasks such as defect detection, predictive maintenance, process modeling, material design, and human–robot collaboration. The review highlights emerging trends, methodological trade-offs, and practical challenges shaping the future of synthetic data in intelligent manufacturing systems. In addition to consolidating recent work, the review identifies underexplored research gaps and methodological challenges that shape future directions in synthetic data use for manufacturing AI.

In aircraft assembly, the low structural stiffness of industrial robots complicates surface quality control, and the opacity of conventional machine learning models hinders their adoption for process optimization. To address this, this paper presents a systematic Explainable AI-Guided Feature Refinement Framework to develop a minimal, yet robust, and physically interpretable model for surface roughness prediction in robotic drilling. The framework utilizes SHapley Additive exPlanations (SHAP) as an active component in an iterative feature selection process to refine a Random Forest model. The experimental validation on an integrated industrial platform demonstrates that this approach successfully identifies a minimal set of critical features from a high-dimensional dataset, including process parameters and specific vibration characteristics. The resulting model achieves superior predictive performance and stability compared to conventional feature selection methods. Furthermore, the analysis uncovers key non-linear relationships and feature interactions, providing interpretable insights into how operational parameters and dynamic responses collectively influence surface quality, which facilitates process optimization in robotic aircraft assembly.
在飞机装配中,工业机器人的低结构刚度使表面质量控制变得复杂,而传统机器学习模型的不透明性也阻碍了它们在工艺优化中的应用。为了解决这个问题,本文提出了一个系统的可解释的人工智能引导特征细化框架,为机器人钻井中的表面粗糙度预测开发一个最小的、鲁棒的、物理可解释的模型。该框架利用SHapley加性解释(SHAP)作为迭代特征选择过程中的主动组件来改进随机森林模型。在集成工业平台上的实验验证表明,该方法成功地从高维数据集中识别出最小的关键特征集,包括工艺参数和特定振动特性。与传统的特征选择方法相比,所得模型具有更好的预测性能和稳定性。此外,该分析还揭示了关键的非线性关系和特征相互作用,为操作参数和动态响应如何共同影响表面质量提供了可解释的见解,从而促进了机器人飞机装配过程的优化。

In these turbulent times, companies are forced to rethink their operations every now and again. Naturally, their supply chains represent one of the main focuses of this process. The results of an industrial project on the analysis and potential restructuring of the European distribution network of a global manufacturing company are presented in the paper. In addition to providing the cost-optimal solution, it is demonstrated how the optimal network structure depends on the parameters of the considered cost factors. The consequences of the possible restructuring of the network on the transportation-related CO2 emission are also treated.

Automotive contract manufacturers in Europe encounter significant market challenges due to the evolving market landscape towards e-mobility. This change involves a shift to smaller batch sizes and an expansion of the product portfolio. Further, the increased variety also raises the probability of production idleness caused by supply chain disruptions, which challenge production planning and control. This paper presents an integrated re-planning approach on the production capacity and sequence. We consider capacity and sequence restrictions, as well as the utilization of the production itself. An ILP is formulated for solving the problem and enabling further sensitivity analysis and risk reduction.

In general assembly in the automotive industry, material handling is crucial in terms of system efficiency and overall costs. Line balancing and optimized cycle times are heavily dependent on the line-side stock layout and assignment. This paper presents a hybrid approach for line-side stock area layout optimization under consideration of worker cost and logistics accessibility. While certain layouts are evaluated by a single-agent production simulation of different product variations, a genetic algorithm is proposed to optimize the layout with respect to multiple criteria. The resulting approach considers line-side stock dimensions as well as accessibility restrictions to enable automated line-balancing.

Data will have an exponentially increasing economic value in the coming years. To harness the economic potential of data e.g. due to machine learning, data sharing is helpful to create the large amount of data needed to train models. For sharing data, the definition of prices for datasets is crucial. While current approaches exclusively take the data science perspective to evaluate the value of data based on quality dimensions, the consideration of a multidimensional assessability for transparent pricing is missing. The contribution of this paper is to sketch a conceptual guideline for assessing sensory-captured manufacturing process data from multidimensional perspectives.
未来几年,数据的经济价值将呈指数级增长。为了利用数据的经济潜力,例如由于机器学习,数据共享有助于创建训练模型所需的大量数据。为了共享数据,数据集价格的定义至关重要。虽然目前的方法完全采用数据科学的角度来评估基于质量维度的数据价值,但缺乏对透明定价的多维可评估性的考虑。本文的贡献是概述了从多维角度评估感官捕获的制造过程数据的概念指南。

This research investigates leveraging internal CNC data for tangential cutting force estimation in turning operations to detect tool wear. The experiment involved recording torque and power of the CNC lathe spindle drive while turning various cutting lengths every time with a new insert. The tangential cutting force was computed based on the recorded data and compared with measurements from external sensors. The analysis revealed a close correlation between the values obtained from both sources, affirming the feasibility of monitoring tool wear through internal CNC data. This approach demonstrates potential for real-time tool condition assessment in machining processes.
本研究探讨了在车削操作中利用内部CNC数据进行切向切削力估计以检测刀具磨损。实验记录了每次用新刀片切削不同切削长度时数控车床主轴驱动的扭矩和功率。根据记录数据计算切向切削力,并与外部传感器测量值进行比较。分析揭示了从两个来源获得的值之间的密切相关性,肯定了通过内部CNC数据监测刀具磨损的可行性。这种方法显示了在加工过程中实时评估刀具状态的潜力。

Dynamically instable milling processes make it difficult to realize efficient and competitive manufacturing applications. Previous investigations have shown that tools with a direction-dependent compliance behavior can increase the process stability by disturbing the regenerative effect. In this work, milling tools with design features that allow simultaneous measurement of the deflection at the tool shank and at the TCP lead to a precise reconstruction of the deflection behavior. Straight-fluted milling tools are suitable for modeling milling processes due to the simplified process kinematics, especially in combination with the asymmetric dynamic properties, and should therefore be used for further modeling tasks.
动态不稳定的铣削过程使得实现高效和有竞争力的制造应用变得困难。先前的研究表明,具有方向依赖柔度行为的刀具可以通过干扰再生效应来提高工艺稳定性。在这项工作中,铣削工具的设计特点是可以同时测量刀柄和TCP的挠度,从而精确地重建挠度行为。由于简化了铣削过程的运动学,特别是结合非对称动力学特性,直槽铣削工具适合于铣削过程的建模,因此应用于进一步的建模任务。

A central task in production engineering is the parameterization of manufacturing processes and machinery. The parameterization has a significant impact on product quality, process efficiency, and profitability of the production. Bayesian optimization (BO) - an adaptive black-box optimization algorithm for efficient and performance-optimal parameterization - has emerged in recent years as a promising alternative to conventional experimental design methods such as design of experiments, one factor at a time, or trial and error. Because optimization of manufacturing processes falls under the responsibility of human process experts, close collaboration between BO and human experts is key to successful optimization. Although first approaches to collaborative BO exist, intuitive dashboards that communicate and explain parameter suggestions and optimization progress to process experts are missing. In this paper, we propose a three-phase pipeline for collaborative BO, motivate the need for a collaborative Bayesian process optimization dashboard and define a total of 15 requirements for the dashboard design. Based on this, we propose a design concept for the BO-dashboard comprising multiple metrics and visualizations to explain parameter suggestions, create transparency in the optimization process, and promote the accumulation of process knowledge.

生产工程的中心任务是制造过程和机械的参数化。参数化对产品质量、工艺效率和生产盈利能力有重要影响。贝叶斯优化(BO)是一种用于高效和性能最优参数化的自适应黑盒优化算法,近年来作为传统实验设计方法(如实验设计、一次一个因素或试错法)的一种有前途的替代方法而出现。由于制造过程的优化是人类过程专家的责任,因此BO和人类专家之间的密切协作是成功优化的关键。虽然协作BO的第一种方法已经存在,但是向流程专家沟通和解释参数建议和优化进度的直观仪表板仍然缺失。在本文中,我们提出了一个用于协作BO的三阶段管道,激发了对协作贝叶斯流程优化仪表板的需求,并定义了仪表板设计的总共15个需求。基于此,我们提出了一种包含多个指标和可视化的BO-dashboard的设计理念,以解释参数建议,在优化过程中创造透明度,促进过程知识的积累。我们以优化超短脉冲激光烧蚀工艺为例,展示了仪表板的实现。通过加强人与人之间的BO协作,我们的目标是在保守的生产工程行业中促进BO的采用。

The parameterization has a significant impact on product quality, process efficiency, and profitability of the production. Bayesian optimization (BO) - an adaptive black-box optimization algorithm for efficient and performance-optimal parameterization - has emerged in recent years as a promising alternative to conventional experimental design methods such as design of experiments, one factor at a time, or trial and error. Because optimization of manufacturing processes falls under the responsibility of human process experts, close collaboration between BO and human experts is key to successful optimization. Although first approaches to collaborative BO exist, intuitive dashboards that communicate and explain parameter suggestions and optimization progress to process experts are missing. In this paper, we propose a three-phase pipeline for collaborative BO, motivate the need for a collaborative Bayesian process optimization dashboard and define a total of 15 requirements for the dashboard design. Based on this, we propose a design concept for the BO-dashboard comprising multiple metrics and visualizations to explain parameter suggestions, create transparency in the optimization process, and promote the accumulation of process knowledge. We showcase the implementation of the dashboard at the example of optimizing an ultra-short pulsed laser ablation process. By enhancing human-BO collaboration, we aim to promote the adoption of BO within the conservative industry of production engineering.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"139 ","pages":"Pages 106-113"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147425113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
