齿根的承载能力主要取决于其圆角几何形状和表面下的完整性，这些都受到硬抛光工艺的影响。本文分析了连续展成磨削中的接触条件，旨在填补有关刀尖和齿根圆角熔深过程中的基本效应的知识空白。为了获得对该过程的基本理解，使用了三维去除模拟软件CutS®。结果表明，模拟数据与实验结果相关的刀具磨损和热负荷的齿轮次表面。因此，磨削烧伤和宏观几何磨损严重制约了陶瓷结合剂刚玉刀具的合理使用。提出了一种计算最大值的解析方法，可用于实际规模。
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 show that 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.maxis presented, which can be applied on a practical scale.
