Monitoring the evolution of dimensional accuracy and product properties in property-controlled forming processes

As recent trends in manufacturing engineering disciplines show a clear development in the sustainable as well as economically efficient design of forming processes, monitoring techniques have been gaining in relevance. In terms of monitoring of product properties, most processes are currently open-loop controlled, entailing that the microstructure evolution, which determines the final product properties, is not considered. However, a closed loop control that can adjust and manipulate the process actuators according to the required product properties of the component will lead to a considerable increase in efficiency of the processes regarding resources and will decrease postproduction of the component. For most forming processes, one set of component dimensions will result in a certain set of product properties. However, to successfully establish closed-loop property controls for the processes, a systematic understanding of the reciprocity of the dimensions after forming and final product properties must be established. This work investigates the evolution of dimensional accuracy as well as product properties for a series of forming processes that utilize different degrees of freedom for process control.

Automated summary

Recent trends in manufacturing engineering disciplines highlight the importance of monitoring techniques in sustainable and economically efficient design of forming processes. Open-loop controlled processes currently neglect the microstructure evolution that determines final product properties. Implementing closed-loop control can significantly improve efficiency by adjusting process actuators according to required product properties, thus reducing postproduction. A systematic understanding of the relationship between dimensional accuracy after forming and final product properties is crucial for successful closed-loop property controls.
