展成磨齿是一种硬光整加工工艺，主要用于满足齿轮在几何形状和表面质量方面的高要求。目前，工艺力预测是基于实验研究和仿真相结合。然而，由于材料去除机制的复杂性，该过程的模拟仍然是一个挑战，尚未完全理解。为了缩小这一差距，需要对该过程的微观尺度进行分析。这项工作的目的是分析的机械力在考虑随机接触的颗粒和材料去除机制的影响的过程中。通过研究试验过程中的比能k，验证了这种影响。通过结合工艺参数和晶粒形状分析划痕几何形状来评估比能k。发现了比能k与工艺参数以及晶粒形状之间的相关性，并提出了一种确定比能的方法。
Generating gear grinding is a hard finishing process mainly used to meet the high requirements for gears in terms of geometry and surface quality. Currently, the process force prediction is based on a combination of experimental investigations and simulation. However, the simulation of the process is still a challenge due to the complexity of the material removal mechanism which is not yet completely understood. In order to close this gap, an analysis on the micro scale level of the process is required. The aim of this work was to analyse the mechanical forces during the process considering the stochastic contact of the grains and their influence on the material removal mechanism. This influence was verified by the investigation of the specific energy k during the tests. The evaluation of specific energy k was performed by means of the analysis of the scratch geometry in combination with the process parameters as well as the grain shape. A correlation between the specific energy k and the process parameters as well as the grain shape was found, and a method for the determination of the specific energy was developed.
