Manufacturing simulation for the analysis of the gear hobbing process

Maximum removal rates and reliable, reproducible processes are of crucial importance for modern production operations. This applies particularly to the use of coated cemented carbide tools for dry hobbing. In current industrial practice, however, even slight changes in the cutting parameters and tool geometry result in significant fluctuations in tool life behaviour. As part of the task of determining chip formation parameters for gear hobbing, a penetration calculation is used to infer parameters characterising tool life behaviour from the chip geometry and cutting kinematics. This paper presents the achievable results by means of some examples.
