The production of modern cutting tools, e.g. end mills or drilling tools, is very challenging. On the one hand, the requirements regarding the tool quality and tool lifetime are continuously increasing due to new manufacturing processes and workpiece materials. On the other hand, there is an increasing demand for cutting tools and the productivity of the tool production process has to increase in order to satisfy the world market. In order to solve both challenges, new tool grinding processes have to be developed. This paper presents a modification of the generating gear grinding process that allows the production of rotationally symmetric cutting tools. The advantage of this manufacturing process is the simultaneous machining of all cutting edges and the flutes of the workpiece in one continuous process. Therefore, auxiliary process times are reduced and new tool geometries are producible, which are not machinable using conventional tool grinding processes.

现代切削工具（例如立铣刀或钻孔工具）的生产非常具有挑战性。一方面，由于新的制造工艺和工件材料，对刀具质量和刀具寿命的要求不断提高。另一方面，对切削工具的需求不断增长，并且为了满足世界市场，必须提高工具生产过程的生产率。为了解决这两个挑战，必须开发新的刀具磨削工艺。本文介绍了对发电齿轮磨削工艺的一种改进，它允许生产旋转对称的切削刀具。这种制造方法的优点是可以在一个连续过程中同时加工所有切削刃和工件的凹槽。因此，
