Wear Resistance of Coating Films on Hob Teeth

Autor: Yoji UMEZAKI, Yoshiyuki FUNAKI, Syuhei KUROKAWA, Osamu OHNISHI, Toshiro DOI

Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 6, Iss 2, Pp 206-221 (2012)

The wear resistance of coating films on hob teeth is investigated through the simulated hobbing tests with a flytool. The coating films on hob teeth are titanium family ceramics such as TiN, TiCN, TiSiN and TiAlN and aluminum chromium family ceramics

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

Autor: Yoji Umezaki, Syuhei Kurokawa, Yasutsune Ariura

Publikováno v: Key Engineering Materials. 437:189-193

The transient phenomenon of chip generations and behavior in the gear hobbing process are investigated by using a high-speed video camera. The chip behavior generated in gear finish hobbing process is very complicated and one can not identify each ch
