Through literature research and empirical data, these indices are established and material properties are derived and analyzed.

In this regard, developing accurate models is crucial for understanding and optimizing the residual stress in Hybrid Wire-Arc DED. This paper investigates the challenge of predicting the residual stress in Hybrid Wire-Arc DED using the Finite Element Method. Interlayer milling interventions are simulated by modelling material removal as a predominantly geometric effect through element deactivation, excluding the thermo-mechanical effects of cutting.

This article proposes an edge-server collaborative data architecture collecting crucial CNC machine data, including servo motor parameters, cutting tool information, and sensor data such as vibration, pressure, and temperature. The architecture is designed to process real-time data during mass production with minimal latency, considering the high-speed nature of machining processes, while also storing historical data in a Data Lake for the development of AI models. An infrastructure for Digital Twin of the brake disc machining process is created, a particularly challenging task due to the complex geometry of the disc and the unique material characteristics of cast iron. During machining, sudden tool failures or even brake disc breakages can occur due to the heterogeneous nature of cast iron. Given that brake discs are critical safety components in automobiles, monitoring process data linked to the cast iron and cutting tool supply chain during mass production is essential. Digital Shadow serves as a foundation for real-time anomaly detection, predictive maintenance, and tool wear prediction models. This paper also proposes several deterministic modeling approaches for real-time anomaly detection, predictive maintenance, and remaining useful life predictions for cutting tools. These models leverage machine data such as spindle and feed-drive motor currents, load, and positional errors during brake disc machining, in combination with sensor data, including temperature, pressure, electrical power, and vibration, to enhance the monitoring and optimization of the machining process.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"133 ","pages":"Pages 406-411"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759208","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}

In this context, sandwich structures comprising a soft-elastic foam core and organic sheets as face sheets are of particular interest. The soft-elastic foam core allows for the integration of acoustic and thermal insulating properties while enabling low-damage forming.
