滚齿仍然是一种切割技术，高速钢在现代制造实践中继续得到广泛应用。由于磨损试验的持续时间很长，滚刀设计的改进是有问题的。为了提高研究的生产率，在五轴铣床上开发了一种名为“飞滚”的类比加工工艺。研究了在干式高速制造条件下，刀具刃口准备对粉末冶金高速钢齿轮滚刀耐磨性的影响。独创的基于磨料流加工技术的刃口加工工艺大大提高了刀具的使用寿命。
Gear hobbing remains a cutting technology where high speed steels continue to find wide applications in modern manufacturing practice. The improvements in hobbing tool design are problematic due to the very long duration of wear tests. The application of an analogy process called ‘fly hobbing’ has been developed on a five-axes milling machine so as to improve the productivity of the investigations. This process has been used to investigate the influence of the cutting edge preparation on the wear resistance of gear hobs made of PM-HSS in the context of dry high-speed manufacturing. An original edge preparation procedure, based on the abrasive flow machining technology, has revealed a great improvement of the tool life.
