Dr. habil.-Ing. Tadeusz Sałaciński is an associate professor at Warsaw University of Technology’s Institute of Manufacturing Technologies. His main interests are cylindrical gears, spiral bevel gears, non-circular gears, metrology, statistical process control, production engineering, cutting tool design and manufacturing technology.
The toothed belt and pulley system known by the designation T, which has been selected as an example within this paper, was developed in the 1950s and standardized first in DIN 7721 (1977) and then in ISO 17396:2014. In this case study, the authors check if a single hob can properly cut T5 profile pulleys with 25 and 30 teeth—and if
so, define the range of the number of teeth covered by this hob.
