A device has a work piece spindle for accommodating a bevel gear work piece, a tool spindle for accommodating a grinding wheel having an abrasive surface, and a plurality of drives for machining the bevel gear work piece. During machining of the bevel gear work piece, the grinding wheel rotates about the rotational axis of the tool spindle and engages the bevel gear work piece to remove material. The rotation is superimposed with an eccentric movement such that the grinding wheel only engages the bevel gear work piece at n contact regions of the abrasive surface. The device is configured to allow adjustment of the eccentric movement after a first machining phase and to specify m contact regions of the abrasive surface in a further machining pase, wherein the m contact regions do not overlap with the n contact regions.

B23F 5/16 - Making straight gear teeth involving moving a tool relatively to a workpiece with a rolling-off or an enveloping motion with respect to the gear teeth to be made by planing or slotting the tool having a shape similar to that of a spur wheel or part thereof
The invention relates to a coordinate measuring apparatus (10), comprising a sensor (30) that is movable relative to a component (12) to be measured. A movable first component (16) carries the sensor (30) and is movably guided on a movable second component (20) along a linear axis (z). The second component (20) is designed as a hinged arm (22), which at a first end (22a) is mounted by a first hinge joint (24) fastened to a supporting structure (14) such as to be rotatable about a first rotational axis (26). At a second opposite end (22b), the hinge arm (22) carries the first component (16). Between the two ends (22a, 22b), the hinge arm (22) has a second hinge joint (34) which has a second rotational axis (36) parallel to the first rotational axis (26) and which divides the hinge arm (22) into a first and a second arm (31, 32), which arms are rotatable independently of each other about the first and the second rotational axis (26, 36), respectively. The hinge arm (22) and the one linearly movable component (16) replace the three linearly guided components required in a customary coordinate measuring apparatus of gantry design having a stationary gantry, which increases the measuring accuracy because said hinge arm (22) and movable component (16) cause substantially fewer errors than extended linear guides.
