The accuracy of grinding hobs is based on applying the approach in practical manufacturing. Taking two typical different kinds of pre-grinding gear hobs as …

The relief surfaces are ground using the same double-cone grinding wheel as grinding the helical surfaces of the worm. Based on the theory of gearing, the mathematical model for grinding relief surfaces is built. Motion parameters when grinding the different points of the land edges on different teeth of the hob are solved.

Unlike the traditional worm gear hob which can use the principle of optical projection to detect the hob shaft section and compare with its mathematical model, currently, there is no standard mathematical model to detect the shaft section of hourglass worm gear hob.

The hobs were ground on a special conventional grinder for sharpening cutter hobs using a dish-type grinding wheel, namely 38A60KVBE by Norton . This is a soft grinding wheel (K grade), made from white fused alumina, and used for precise and finish grinding of hard (>57 HRC) and burn-sensitive steels, e.g. high-speed cutting steels.

Accurate gear hob is the guarantee of high-precision gear machining and at the same time, hob relief grinding is a key process for hob precision manufacturing. With the increasing accuracy requirements of gears, various researchers have made efforts to improve the accuracy of the hobbing process.
