Data-based Process-Integrated 3D-Measurements of Magnesium Parts for Lightweight Car Body Construction 2021-01-0241
The aim of a research project was to develop a system for the analysis, processing and addressing of data flows of process-integrated 3D-measurements of magnesium workpieces for car body construction and its prototypical application. By applying optical measuring methods for quality control and using object-specific measurement for process control, considerable savings of energy and other resources can be achieved in automotive engineering.
The QM standards for measuring systems for forming processes in the automotive sector place high demands on accuracy and measuring speed. By using multi-camera systems, clock rates of less than 10 seconds and accuracies of 30-40 μm over the entire measuring range can be guaranteed. The modular design of a system facilitates process integration due to the relatively low effort required for different manufacturing tasks.
The performance analysis of the measuring system and the process landscape design were carried out. Then, the parameters for process control and the overall measuring concept could be derived. The underlying operational processes were modelled in detail using value chain diagram, event-driven process chain and Petri nets. A simulation model was created. The workflows for fault finding and procedures for information addressing were integrated into the process models based on a rule-based system.
Furthermore, reference parts were selected. The target geometries and actual 3D-geometries were generated. The tests with many raw data were analytically assessed. A concept for the data base solution, including the software adaption, had to be developed. For the integration into an I4.0 environment, the requirements for human controllability including competencies, authorizations and organizational mechanisms were described. The design of HMI artefacts and the workstation dashboard were defined. Finally, a laboratory prototype was developed to prove the system functionality in practical operation.
