One of the main challenges in generating gear grinding is the determination of cutting forces due to their significant influence on the dynamics of the grinding process. Thus, optimizing the cutting forces can lead to an increased quality of ground gears and a minimized wear behavior of the grinding worm. Currently, the knowledge of the generating grinding process is limited and research is based mostly on empirical studies. A theoretical model which help to predict the cutting forces is

... . This paper presents an initial approach for calculating the complex contact conditions in generating gear grinding as well as cutting forces and key values to characterize the process. This approach gains more and more importance especially for large module gears, to reduce manufacturing costs. By means of the calculated forces, the manufacturing process can be optimized and the quality of the manufactured gear can be increased.
