In order to evaluate performance and wear of gear cutters and coatings, various analogy cutting tests are nowadays used. Since these state-of-the-art tests significantly differ in complexity and comparability to real dry hobbing applications, this work presents a critical literature comparison highlighting the different characteristics, and further introduces a new approach to adjust the appearing...
In the module range of 1.5 – 4mm hobbing is still the most productive process for external gears. The trend for green manufacturing and the increasing cost pressures lead to an increase of dry hobbing. To apply dry hobbing, the cutting speed has to be increased compared to wet cutting. This paper shows that dry hobbing with PM-HSS is feasible and economic. Additionally, a method to determine guide...
