最新的研究清楚地证明了齿轮打滑过程的卓越能力。为了进一步改进工艺，特别是提高工艺的可靠性，进行了基础科学研究。本文给出了过程运动学和切屑形成机理的研究结果。首先将描述实验分析，这是开发和验证模型的基本基础。在进一步的实验中，确定了试验材料SAE 5120的材料行为，并建立了材料模型。该过程的建模是这项研究的一个中心方面。这包括3D模型中运动学的基本建模。通过仿真，可以分析运动条件和切屑形成机制，并评估对工艺可靠性的影响。研究结果支持工具和工艺设计，是工艺实施的重要依据。
Latest research clearly demonstrates the excellent capability of the gear skiving process. For further improvement of the process and particularly for the enhancement of the process reliability fundamental scientific research is conducted. In this paper the result of investigation of process kinematics and chip formation mechanisms are presented. First the experimental analyses will be described, which represent an essential basis for developing and validating the models. In further experiments the material behavior of the test material SAE 5120 was determined and a material model was developed. The modeling of the process represents a central aspect of the research. This includes the basic modeling of the kinematics in a 3D-model. The simulation enables analysis of the kinematical conditions as well as the chip formation mechanisms and evaluation of the effects on process reliability. The results support the tool and process design and are an important basis for the implementation of the process.
