Abstract
This invention concerns a method for the synchronization of a gear machining instrument that works according to the hobbing method. It has different drives for the tool and the work-piece. In the process, a series of pulses are produced, dependent upon the rotational speed of each drive. The occurrence of the pulses are compared digitally resulting in an analog control signal for the adjustment of the work-piece drive.
