Software-Based Process Design in Gear Finish Hobbing
The article "Software-Based Process Design in Gear Finish Hobbing" appeared in the May 2010 issue of Gear Technology.
In this paper, the potential for geometrical cutting simulations - via penetration calculation to analyze and predict tool wear as well as to prolong tool life - is shown by means of gear finish hobbing. Typical profile angle deviations that occur with increasing tool wear are discussed. Finally, an approach is presented here to attain improved profile accuracy over the whole tool life of the finishing hob.
