VDI Accolade for Student Thesis

This year Lars Stahmann, graduate of the University of Bremen’s Faculty of Production Engineering, receives the engineering prize awarded each year by the Bremen chapter of the Verein Deutscher Ingenieure (VDI) [German Association of Engineers]. Stahmannn convinced the jury of his excellent knowledge of engineering with a Diplom thesis entitled “Determining temperature profiles of static and rotating components during external hardness grinding”. His thesis is based on studies in the subject Production Processes in the Department of Production Engineering at the Institut für Werkstofftechnik (IWT), and describes how new savings potentials may be realized in metal hardening processes.

The process

The process of external grinding is used to harden the outer layers of components while the parts are being machined, saving time and money in the manufacturing process. The influence of temperature fluctuation in the component layers during grinding plays an important role. In his thesis, Stahmann describes the interactions involved during the process. In so doing, he carried out temperature measurements of the widely used steel material 100Cr6 during external hardness grinding at different process settings. The result: a description of the process window that results in the best choice of setting.

The Bremen Engineering Prize is awarded annually for the two most outstanding and innovative Diplom, Bachelor or Master theses that combine a high level of engineering achievement with potential for practical application. Lars Stahmann receives an award of 1,000 euros. His thesis was supervised by Prof. Carsten Heinzel and Dipl.-Ing. Benjamin Kolkwitz.
