磨削加工的结果，如表面粗糙度或磨削烧伤，通常由刀具规格和工艺参数的使用来表征，但也由几何接触来表征。虽然接触长度或接触面积以及比去除率的计算对于平面或外圆磨削等工艺有明确的定义，但它们仍然是连续展成齿轮磨削的研究领域。在科学环境中，连续展成磨削的接触参数已经通过数值模拟计算。但接触参数对仿真软件的依赖性限制了其工业实用性。在生产工程和机床研究所的实际齿轮加工分析中，重点之一是连续展成磨削的几何接触值的分析建模。本文提出了接触区的几何模型，并通过数值模拟进行了验证。因此，计算值和模拟值之间的高度相关性出现。
The results of grinding processes like surface roughness or grinding burn are often characterized by the usage of the tool specification and process parameters but also by the geometrical contact. Whereas the calculation of contact length or contact area as well as the specific removal rate is clearly defined for processes like plane or cylindrical grinding, they are still a field of research in context of continuous generating gear grinding. In the scientific environment the contact parameters for continuous generating grinding have been already computed via numerical simulations. But the dependency of the contact parameters on the simulation software restricts their industrial usability. One of the focuses in the actual gear machining analysis at the Institute of Production Engineering and Machine Tools is the analytical modeling of the geometrical contact values for continuous generating grinding. In this paper the geometrical model of the contact area is presented and validated via numerical simulation. Thereby, a high degree of correlation between calculated and simulated values arises.
