Development and optimization of the hard gear skiving in the productive dual-flank-cutting for gearings

齿轮滚切作为一种高效、灵活的加工工艺，近年来在工业上得到了长足的发展。在难加工中，该工艺目前很少再使用了。由于生产效率较低的单面切割方法和较高的工具成本，市场上没有实现大规模生产。硬齿面刮削工艺的演变或硬齿面刮削工艺的基础科学研究至今仍未见报道。本项目的目标是开发出最终优化的生产性双面切割。调查将基于工具和工艺设计以及机械工程方面的软加工经验。利用计算机辅助工艺设计和实验研究来优化工艺参数，特别是淬火余量。因此，将获得切割材料和涂层材料的适当组合、优化的工艺参数和最佳的工艺设计的知识。实验研究将证明该工艺与现有的齿轮硬态精加工工艺相比的性能，并将能够说明性能、时间和成本。

Gear Skiving as productive and flexible cutting process has recently experienced a significant development towards a lasting industrial establishment. In hard machining, the process is currently rarely used anymore. A large establishment in the market was not achieved due to the less productive approach of single-flank-cutting and high tooling costs. An evolution of the hard gear skiving or basic scientific research of hard gear skiving process is still missing entirely. The aim of this project is to develop the productive two-flank-cutting with final optimization. The investigations will be based on the experience of soft machining regarding tool and process design and mechanical engineering. Computer-aided process design and experimental studies are used to optimize the process in terms of process parameters and in particular the hardening allowance. As a result, knowledge of suitable combinations of cutting material and coating material, optimized process parameters and the optimal process design will be available. The experimental studies will demonstrate the performance of the process in comparison to the established processes of hard finishing of gears and will allow statements of performance time and costs.
