Sharpening helical hobs with a hob sharpener is relatively easy and efficient, but the hob sharpener has poor versatility due to its tilted spindle for sharpening helical flutes. In this paper, we propose a new solution for sharpening helical flute hobs. Geometrically, we simplified the wheel profile to a circular arc, which made it easy to obtain the wheel profile through the circular arc NC (numerical control) function G02 or G03. With the simplified wheel profile, it is much easier to obtain the profile of the wheel made with CBN (cubic boron nitride), even with the use of an ordinary CNC (computer-aided numerical control) contour dressing machine. We also calculated the machine settings for a 5-axis form grinding machine, in which the machine settings of a hob sharpener were transformed into through coordinate transformation. With such new machine settings, the helical flute hob can be sharpened by the form grinding machine. Finally, our numerical examples evaluate the variations between the proposed simplified circular arc wheel profile and the theoretical one. Moreover, the results of our experiment using the form grinding machine with the simplified circular arc profile wheel are illustrated in the plots of the measuring machine.

用滚刀磨刀器磨削螺旋滚刀相对容易和有效，但滚刀磨刀器由于其倾斜的主轴用于磨削螺旋槽，因此通用性较差。在本文中，我们提出了一种用于刃磨螺旋槽滚刀的新解决方案。在几何上，我们将车轮轮廓简化为圆弧，这样可以通过圆弧NC（数控）功能G02或G03轻松获取车轮轮廓。通过简化的砂轮轮廓，即使使用普通的 CNC（计算机辅助数控）轮廓修整机，也更容易获得由 CBN（立方氮化硼）制成的砂轮轮廓。我们还计算了 5 轴成型磨床的机器设置，其中通过坐标转换将滚刀磨床的机器设置转换为。有了这样的新机器设置，螺旋槽滚刀可以通过成型磨床进行磨锐。最后，我们的数值例子评估了所提出的简化圆弧轮轮廓与理论轮廓之间的变化。此外，我们使用带有简化圆弧轮廓砂轮的成形磨床进行的实验结果在测量机的图中进行了说明。
