Abstract During the running production of automotive body components drifts in theprocess window is seen causing problems with non-conforming parts. Up until now, these driftshave been counter-acted based on the knowledge and experience of the press line operators.This experience-based process control will however become more troublesome in the future asrecycled material grades will undoubtedly present […]

The machine tool investment for stamping (presses and tools) is cost intensive in the automotive industry. The machine tool investment for stamping (presses and tools) is cost intensive in the automotive sector. Maximizing return on investment (ROI) against these assets is crucial for maintaining a healthy bottom line. Additionally, minimizing the amount of scrap is […]

8th of October was the Academic Ceremony at BTH with promotion of PhD’s and installation of professors among other things on the agenda. From Product Development Research Lab and the research subject of Mechanical Engineering we were very happy to see the installation of two new professors in Marco Bertoni, and Sophie Hallstedt. We also […]

Abstract Cost and time for die tryout are significant within the car industry, and elastic deflections of dies and presses are most commonly not considered during the virtual die design and forming simulation phase. Because of this, active surfaces of stamping dies are only cambered based on previous experiences of tool types and presses. However, […]

Abstract Ability to predict and control involved parameters and hence the outcome of sheet metal forming processes demand holistic knowledge of the product/-process parameter influences and their contribution in shaping the output product quality. Recent improvements in the ability to harvest inline production data and the capability to understand complex process behaviour through computer simulations […]

Concluding remarks and results PREDICT has generated results and tools that are used to increase reliability of failure prediction of sheet metal forming simulation in finite element models (FE-model). The work in this project was focused to accurately model the effect of complex load cases like non-linear strain path (NLSP), stretch-bending and presence of edge […]
