Method for the discontinuous grinding of bevel gears and corresponding software for controlling a multiaxis grinding machine

A multiaxis grinding machine comprising software for controlling said multiaxis grinding machine, which is designed for the chip-removing machining of the tooth flanks of a gear wheel having n teeth and n tooth gaps in the single indexing method, a grinding disc, which may be dressed, being used for the machining and one of the n tooth gaps after another being machined discontinuously using this grinding disc, characterized in that the software controls the machining sequence during the execution by the grinding machine in such a way that, at the beginning of the machining of the gear wheel, after the insertion of a freshly dressed grinding disc in the grinding machine, the following steps are executed:

• a) plunging the grinding disc at the beginning of the machining of the gear wheel using a predefined first restraint in relation to a normal predefined plunging depth into m of the n tooth gaps, to pre-machine these m tooth gaps, whereby m=1, 2, or 3 and m<n,
• b) subsequently machining the remaining n−m tooth gaps using the predefined plunging depth, and
• c) finally post-machining the m tooth gaps using the grinding disc, the grinding disc plunging into these m tooth gaps during this post-machining using a predefined second restraint in relation to the normal predefined plunging depth.
