Abstract
A hob cutter (4) for machining face or crown gears comprises a disc-like cutter body having an axis of rotation (6) and a number of hob teeth groups (1, 2, 3, . . . ) which are uniformly distributed over the circumference and which are each bounded at the front by a cutting face (S) and at the cirumferential side by a clearance face (V). The cutting face and the clearance face of each hob teeth group intersect one another in a cutting edge (9) which determines the shape of the face gear to be machined. The clearance face of each hob teeth group is made up of a number of generatrices (L, m) which are each situated in a machining plane which is determined by a line which intersects or crosses the axis of rotation (6) perpendicularly and intersects the generatrix at the position of the cutting edge. The extensions of the generatrices (L, m) determining the clearance face run at a minium spacing over the outside of the downstream hob teeth group.
