ABSTRACT:
A method of controlling the positioning and/or speed of axes on a machine tool as well as an apparatus for carrying out the method. The inventive method controls the positioning and/or speed of fast-rotating, high-accuracy orbital axes (i.e. rotational axes) of a gear-manufacturing machine, wherein a standard NC is used. The inventive method and apparatus are realized by the inclusion of a second control system which is provided in addition to the standard NC and is structured such that the known aliasing effects generated by underscanning and the limitation of the dynamics by the cycle times are avoided or considerably reduced. By application of the inventive method, higher accuracy can be attained while maintaining the full functional scope of the standard NC.
