Dr.-Ing. Mareike Solf studied mechanical engineer-ing with a focus on production technology at RWTH Aachen University. Having worked as a student research assistant in the department of Gear Technology of the Laboratory for Machine Tools (WZL) for more than three years, she became a research assistant in 2016. Her research focused on grinding and 5-axis-milling of bevel and cylindrical gears. After leading the Gear Hard Machining Research Group since early 2019, she became Chief Engineer for Gear Manufacturing in November 2021. In 2022 she completed her Ph.D. on the topic of bevel gear grinding.
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.
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.
