Method for machining bevel gears using an indexing method having complete indexing error compensation

A method for producing bevel gears (31) compensated for workpiece indexing error, using a device (20) which comprises a workpiece spindle (42) for receiving the bevel gear (31), a tool spindle (42) for receiving the tool (24), and multiple drives (X, Y, Z, B, C, A1) for machining the bevel gear (31) using the tool (24) in the single-indexing completing method, having the following steps:

• predefining master or neutral data which describe the shape of a bevel gear (31) to be mass produced and the required machine tool kinematics,
• executing the following machining steps on the basis of the master data or neutral data,
• a) machining one tooth gap of a sample workpiece using the tool (24) by executing a machining movement,
• b) executing a relative movement between the tool (24) and sample workpiece to remove the tool (24) from the tooth gap,
• c) executing an indexing rotation to transfer the sample workpiece into another angular position,
• d) machining a further tooth gap of the sample workpiece using the tool (24) by repeated execution of steps a)-c), these steps being repeated until all tooth gaps of the sample workpiece are manufactured,
• transferring the sample workpiece to a measurement system (10),
• ascertaining an indexing error of each tooth of the sample workpiece,
• ascertaining correction values or correction factors per tooth or tooth gap for correcting said indexing error, one tooth or tooth gap of the sample workpiece being used as a reference,
• transmitting or accepting the correction values or correction factors,
• adapting the machine data or neutral data of the device (20) on the basis of the correction values or correction factors as a preparation for the manufacture of at least one bevel gear (31) compensated for indexing errors,
• producing at least one bevel gear compensated for indexing errors using the adapted machine data by executing steps a)-d), these steps being repeated until all tooth gaps of the bevel gear (31) compensated for indexing errors are manufactured.
