DRESSING OF ABRASIVE WHEEL Russian patent published in 2015 - IPC B24B53/75 

FIELD: process engineering.

SUBSTANCE: invention relates to machining and can be used for dressing of grinding wheel for relief of hobs at NC machines. Dressing tool composed of diamond needle or stick is positioned relative to grinding wheel and set at sand machine in the area of hob to be relieved. It is displaced relative to grinding wheel in preset curvilinear path in several passes. Dressing tool feed is performed in path identical to the edge of hob to be relieved. After every pass, dressing tool is fed by its turning around z axis of said hob through angle δ=0.1÷1.5° and relative to the grinding wheel surface by magnitude u parallel with axis z and magnitude w perpendicular to said axis z. Said magnitude u and w are taken equal to displacement of the hob relative to grinding wheel at hobbing, respectively, along hob axis z and perpendicular thereto during its turn around axis z through angle δ.

EFFECT: higher hobbing precision, enhanced hob performances.
