Gear hobbing is a highly utilized flexible manufacturing process for massive production of
external gears. However, the complex geometry of cutting hobs is responsible for the almost
exclusive utilization of high-speed steel (HSS) as cutting tool material. The limited cutting
performance of HSS, even coated HSS, restricts the application of high cutting speeds and
restricts the full exploitation of modern CNC hobbing machine tools. The application of
cemented carbide tools was considered as a potential alternative to modern production …

Gear Hobbing is a complex gear manufacturing method, possessing great industrial
significance. The convoluted geometry of the cutting tools brings on modeling problems and
is the main reason for the almost exclusive application of HSS as cutting material. However,
despite its complicated kinematics, gear hobbing is sufficiently described by well-
established software tools, which were presented in the first part of the present paper.
Experimental investigations exhibited the cutting performance of cemented carbide cutting …
