Modeling the Thermoforming Process of UD Laminates in Process Planning Software
In this cooperation project between IKV, the Institute for Human-Machine Interaction (MMI) and the Fördervereinigung Programmiersprachen e.V. (FVP), the thermoforming process of UD tape laminates is mapped in a software for process planning and control.
© IKVAn expert system supports the selection of the optimum tool technology by taking into account the tool characteristics and component specifications. To this end, design guidelines were created that link user requirements and tool parameters. The implementation of the expert system in Python enables case-based decision-making for tool selection. Feedback from the production level is incorporated into the continuous improvement of the system, in particular through the analysis of quality data and empirical knowledge. A developed interface enables the feedback of errors and potential countermeasures in a 3D environment in order to further refine the expert system and adapt it to real production conditions. The mould settings derived from this system are then used to adjust a shape-adaptive pin mould to the corresponding cavity shape and to form the previously optimised laminate.
