One key component of powertrains is gears which are used in a continuously increasing quantity with improving quality. A productive process for finishing gears is the generating gear grinding process. The process is used mainly for large-batch production of small or mid-size gears after case hardening, especially in the automotive sector.

Currently, the knowledge regarding the generating grinding process is limited and research is based mostly on empirical studies. The reasons for this are complex contacting conditions as well as the undetermined interactions between various process parameters.

This paper focusses on current questions about generating gear grinding such as new approaches for a simulation based process design in consideration of cutting forces as well as the changing contact conditions.
