Zusätzlich werden Unsicherheiten durch Modellfehler sowie externe Einflüsse in die Methode eingebunden. Dadurch wird eine kollaborative Planung umgesetzt, die zu robusten Ergebnissen führt.   Planning of manufacturing process chains across companies is a great challenge due to technological interdependencies. This paper presents a planning method enabling cross-company manufacturing cost optimization with decentralized modules. In addition, uncertainties due to model errors as well as external factors made are integrated into the method. This allows for collaborative planning and leads to robust results.","PeriodicalId":37621,"journal":{"name":"WT Werkstattstechnik","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69691954","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 dieser Arbeit soll das Polygon-Formen für die Herstellung sphärischer Segmente erweitert werden. Polygon forming of large structural components for the aerospace industry brings numerous advantages compared to conventional forming processes, such as lower material stresses and fewer pre- and post-processing steps. So far, this technology has only been used for the production of cylindrical or conical fuselage segments.

The acquisition of data during the hot forging process is currently a major challenge. Therefore, this paper presents a universally applicable system for measuring and recording the temperatures of the billet and dies, forging forces and stroke paths.

Der Beitrag untersucht, wie diese Versuche durch künstliche Intelligenz (KI) unterstützt und sich die Anzahl notwendiger Versuche reduzieren lassen.   The cutting process of semi-finished products by means of band saws is often the first step in producing parts. So far, the lack of simulative investigations usually meant that machining parameters for this process had to be determined experimentally at great expense.
