A method for machining and measuring workpieces includes: machining a workpiece by a gear cutting process, wherein a tooth flank of the workpiece is produced or machined; measuring an actual geometry of the tooth flank produced by the gear cutting process by a measuring process; determining a deviation of the actual geometry from a predetermined nominal geometry of the tooth flank; determining a corrected gear cutting process for at least partially reducing the deviation; and machining the workpiece and/or a further workpiece by the corrected gear cutting process. The determination of the corrected gear cutting process for at least partial reduction of the deviation has the specification that a distinction is made between first and second evaluation areas of the tooth flank, wherein first and second permissible deviations of the actual geometry from the nominal geometry is specified for the evaluation areas of the tooth flank, respectively.

A bonding member (10) includes surface-processed silver surfaces (11a, 11b).

A machine tool (1) for processing gears comprises a workpiece spindle (16) for driving a workpiece (18) to rotate about a workpiece axis (C1), and a tool spindle (11) for driving a tool (12) to rotate about a tool axis (B). An axial slide (7) is used to change a relative axial feed position between the tool spindle and the workpiece spindle with respect to the workpiece axis. The axial slide is guided along an axial guide direction (Z′) which is inclined with respect to the workpiece axis by an inclination angle (ψ), the inclination angle (ψ) being between 0.1° and 30°.

A lapping device for gear helix artifact with equal common normal by rolling method, use the rotary table to accurately control the angle between the lapping surface of whetstone and the axis of the base-circle cylinder to control the helix angle of base-circle about the involute helicoid. Use the whetstone driven component to drive the whetstone to make a high-precision linear motion in the vertical direction to adjust the position of the lapping surface of whetstone. The distance between the two lapping surface of whetstone is precisely adjusted by the gauge block to control the processing length of the three tooth common normal of the gear helix artifact. The invention provides a lapping device for gear helix artifact with equal common normal by rolling method, it conforms to the generation principle of the involute helicoid, and there is no machining principle error.
