Congratulations to PhD Student Till Böttjer and MSc in Engineering Johan Krogshave, who won the Design for Manufacturing and the Life Cycle (DFMLC) Best Paper Award for their research on energy consumption in milling processes at the international ASME conference on emergent technologies in mechanical engineering.

The two won the prize for developing a data-driven method for improving the accuracy of a widely used analytical model, termed as the Unit Process Lifecycle Inventory (UPLCI) model, for estimating the energy and resource consumption of milling processes.

The UPLCI model is generally applicable to a wide range of machine tools and materials and their research showed that, given a specific machine tool and a material, the model tends to significantly overestimate actual energy consumption. The methodology developed by Till Böttjer and Johan Krogshave under supervision of Assistant Professor Devarajan Ramanujan significantly improves the accuracy of the original UPLCI model making it possible for designers and engineers to proactively optimize specific design and manufacturing setups.

Till Böttjer, originally from Hamburg, Germany, moved to Denmark with his partner Julia in 2018. He and Johan Krogshave, who’s born and raised in Lynnerup, Denmark, are both MSc’s in Engineering from Aarhus University and this paper is the result of their joint master thesis as a part of the Lifecycle Design and Manufacturing research group.

"This is the first time, the Mechanical Engineering Section at Aarhus University has received this prestigious award and, in my mind, it speaks to the excellent quality of research that our students produce at the MSc thesis level. I am very proud of their work," says Assistant Professor Devarajan Ramanujan.

Till Böttjer has pursued a career as scientist and is now a PhD student and part of the research team in the MADE FAST project at Aarhus University and Johan Krogshave now works for the Odense-based robotics company Robot At Work.

Team leader on the research is Assistant Professor Devarajan Ramanujan who’s leading the Lifecycle Design and Manufacturing research group and is a member of the AU DIGIT Center.
