Semi-completing single indexing methods for machining the tooth flanks of a face coupling workpiece. A tool is used which includes at least one cutting head having two cutting edges or two grinding surfaces. Exemplary methods include executing at least one first relative setting movement, to achieve a first relative setting, finish machining a first tooth flank of a tooth gap of the face coupling workpiece using a first cutting edge or using a first grinding surface of the tool and simultaneously pre-machining a second tooth flank of the second tooth gap using the second cutting edge or using the second grinding surface, executing at least one second relative setting movement, to achieve a second relative setting, and finish machining the second tooth flank of the same or a further tooth gap using a second cutting edge or using the second grinding surface of the tool.

Bevel gear having a main body comprises a heel-side skin surface. The bevel gear has at least one tooth gap, which exits from the main body in the region of the skin surface. The tooth gap has a tooth base, the profile of which is defined by a base cone angle in relation to the workpiece axis of rotation. A concentric circumferential ring structure is provided on the skin surface, which is raised in relation to the skin surface, and which results in a heel-side exit angle between the tooth base and the ring structure, which is in the range between 125° and 160°.

A workpiece clamping systems for a measuring machine includes a rotary table disposed in a workpiece rotation axis and includes a chuck for the concentric accommodation of a workpiece, a rotary drive for the rotary table, an upper centering tip mountable or mounted on the measuring machine in the workpiece rotation axis vertically opposed to the rotary table and a lower centering tip mountable or mounted on the rotary table in addition to the chuck for accommodating a workpiece between the centering tips instead of in the chuck, wherein the lower centering tip is provided and formed to be concentrically clamped in the chuck instead of a workpiece, and in that the workpiece clamping system is provided with a conveying device for vertically or vertically and chuck.
摘要:
A method for grinding bevel gears (1), wherein a first grinding tool (2) is used during a first method section and a second grinding tool is used during a second method section. A measurement system (30) is used to carry out a measuring procedure, in which sampling values can be ascertained for at least a part of first flanks of the bevel gear workpiece (1), which enable a statement about the concentricity error of this bevel gear workpiece (1) in the present chucking. Concentricity correction dimensions are ascertained by computer on the basis of the sampling values, and an adaptation of machining movements of the second method section is performed on the basis of the concentricity correction dimensions.
