Item type:Publication, Access status: without files , Capabilities of robot-based double-sided incremental hot-forming of fiber-reinforced thermoplastics(Soc. for the Advancement of Material and Process Engineering, 2026-04); ; ; ; Thermoplastic composites are gaining interest for their good recyclability, in addition to their mechanical performance and light weight potential. However, conventional molding processes for thermoplastic composites, such as hot pressing, require full-surface, geometry-specific molding tools and are therefore associated with high investment costs and long lead times until production can start. This is a strong drawback for manufacturing of small series, prototypes or in case of geometry changes. A promising flexible alternative is incremental forming, where geometry-agnostic tool tips exert local force to successively form the part. This allows for the economical and quick production of small part quantities. This work investigates the capabilities of a novel double sided incremental hot-forming process that employs two cooperating robots to drape a heated organosheet into the targeted shape. The process is assessed regarding mechanical performance, geometric accuracy and economic efficiency. The analysis shows that the presented process is capable of producing a wide variety of geometries with viable accuracy and good mechanical performance. The economic assessment reveals a clear advantage in both lead time as well as per part cost for small lot sizes.Publicationtype: Conference Paper40 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Towards model-based assembly system configuration supported by SysML and AutomationMLThe demands of product individualization and reduced development times are an increasing challenge for current product and production system engineering, as customization processes are still a mostly manual task involving different software tools and paperwork. Due to their manual nature, they are error-prone, leading to long lead times and costly rework. Thus, efficient co-customization of products and their production systems must be enabled by common data models and continuously linked software tools. Complex mechatronic products such as aircraft cabins are more and more likely to be developed via a model-based systems engineering (MBSE) approach using Systems Modeling Language (SysML). In assembly system design, model-based development often relies on AutomationML, a modeling and data exchange format for plant engineering information. To combine these concepts, an approach for assembly system configuration based on a SysML-representation of the product and an AutomationML-represantation of the plant is proposed. After the customer configures a unique product version, the corresponding SysML model will be analyzed by the outlined configuration algorithm to determine necessary changes to the assembly system. Based upon an AutomationML library with digital representations of the available assembly system components and their behavior, these logical and parametric changes will be implemented in the instantiated assembly system model. Using AutomationML, configuration can not only take place on the top-level logical model, but also on specific robot or PLC programs. These can be then used for simulations generating information about assemblability and assembly times, allowing improved design decisions once fed back to the product engineers.Publicationtype: Conference Paper109 - Some of the metrics are blocked by yourconsent settings
