Gm-4 Transient Phenomenon of Chip Generations and Movements in Hobbing(gear Manufacturing)

Impact of High-Speed Image Recognition of Transition Phenomenon of Chip Formation and Chip Flow in Gear Hobbing Process

“…The flytool is set at first at the location of the most preceding cutting edge which cuts the tooth space firstly, and after cutting along the tooth width, it is shifted in the next place and is rotated to the location of the next hob cutting edge in free generation [2]. Thus, single flytool generates the special-shaped gear tooth space instead of many hob cutting edges from one end in the roughing zone to the generation zone.…”

“…The authors have developed a new testing method on a hobbing machine to simulate hobbing mechanisms by a flytool [2]. A special-shaped gear blank is prepared with the help of the numerical hobbing simulator [3] developed by the authors.…”

“…Particurarly, High Speed Steel (HSS) hob is one of the most useful tools. Furthermore, the cutting mechanics in gear hobbing is very complex as mentioned by Umezaki et al (2001Umezaki et al ( , 2008 and Ishimaru et al (2011). Therefore, it is important that improving productivity for gear manufacturing is increased by using carbide tipped hob with heatproof.…”
