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

刮削作为一种高效灵活的切削加工工艺，近年来已取得了长足的发展，并逐渐成为一种持久的工业生产方式。在硬加工中，该工艺目前已很少使用。由于单面切削的生产率较低和刀具成本高，在市场上没有建立起大规模的企业。硬齿面刮削的发展或硬齿面刮削工艺的基础科研仍然完全缺失。本项目的目的是开发具有最终优化的生产性双面切削。这些调查将基于软加工的经验，关于工具和工艺设计和机械工程。计算机辅助工艺设计和实验研究用于优化工艺参数，特别是硬化余量。因此，将获得切削材料和涂层材料的合适组合、优化的工艺参数和最佳工艺设计的知识。实验研究将证明该工艺的性能与齿轮硬精加工的既定工艺相比，并将允许性能时间和成本的声明。

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.
