RESEARCH ON THE TAPERED HOBS

Bulletin of JSME, 1981
The hobs are theoretically reconsidered on their peripheral taper and their rough cutting mechanism. The taper angle under a fixed length of hob varies according to the helix angle of gear and the setting angle and the cutting feed direction of hob. A method of determining the optimum taper shape is described on a calculation example.
