Dr.-Ing. Thomas Bergs

Pro. Dr.-Ing. Thomas Bergs, in his capacity as a member of the board of directors of the Fraunhofer Institute for Production Technology IPT, leads the Process Technology Division and is the Chair of Manufacturing Technology at the Laboratory for Machine Tools and Production Engineering WZL at the RWTH Aachen University. For the main part of his academic qualification, Thomas Bergs studied design engineering at the Rheinisch-Westfälische Technical University, Aachen. He graduated in 1995 having written his diploma thesis at the Engineering Research Center for Net Shape Manufacturing in Columbus, Ohio. In 2001 he went on to earn a doctorate in engineering at the RWTH Aachen University for which he was awarded the Borchers Plaque. He also graduated as an Executive Master of Business Administration in 2011. Thomas Bergs was a research associate in the Process Technology Section at the Fraunhofer Institute for Production Technology IPT in Aachen from 1995 to 2000. In the year 2000, he was appointed Manager of the Laser Engineering Group and of the Business Unit Aachen Tool and Die Making. Since 2001 he has also held the position of Managing Director under Professor Fritz Klocke as institute head. Thomas Bergs has additionally founded the company Aixtooling in 2005, where he became Managing Director until 2018. Core area of the expertise at Aixtooling was tool making for precision glass molding as well as advanced glass optics manufacturing. In 2018 Thomas Bergs was appointed as Professor at the Chair of Manufacturing Technology at the Laboratory for Machine Tools and Production Engineering WZL of the RWTH Aachen University and as Director of the Process Technology Division at the Fraunhofer Institute for Production Technology IPT. As the successor to Professor Fritz Klocke, he is also a member of the Board of Directors of both production engineering institutes. Main focus of his ongoing research activities comply the digital transformation of manufacturing technologies—so called networked adaptive production.

Investigation of the Manufacturability of Topological Modifications Using Adapted Kinematics for Gear Skiving

Gear skiving is used for both soft and hard finishing. As a quality critical final step in hard finishing, the process can be used to create modifications to the tooth flank. At present there is no knowledge of the extent to which topological modifications can be applied by gear skiving. In this report, the feasibility of manufacturing topological modifications on an external gear through adapted kinematics for gear skiving has been investigated.

Force Modeling in Generating Gear Grinding Considering the Grinding Worm Topography

For the research developed in this work, an existing simulation model of the generating gear grinding process based on a penetration calculation approach is used. Further, an extension of the model considering a realistic modeling of the grinding worm topography and the macro movements of the grinding worm during the process is presented. The result of the simulation is the microinteraction characteristics throughout
the grinding of the gear flank. In the end, the information about microinteraction characteristics obtained will be used for the calculation of force and energy in generating gear grinding.

Tooth Root Load Capacity of Additive Manufactured Gears

Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes
