Description
The load carrying capacity of the tooth root mainly depends on its fillet geometry and subsurface integrity, which are affected by the hard finish processes. This paper analyzes the contact conditions in continuous generating grinding and aims to fill the knowledge gap concerning the elementary effects during penetration of tool tip and gear tooth root fillet. In order to obtain fundamental understanding of this process, the three-dimensional removal simulation Software CutS®was used. The gained results showthat the simulated data correlate to experimental results concerning tool wear and thermal load on gear subsurface. Thereby, the reasonable use of vitrified bond corundum-tools is severely restricted by grinding burn and macro-geometrical wear,which can be described by the tool surface normal feed rate vfn.max. An analytical approach to the calculation of vfn.max is presented, which can be applied on a practical scale.
