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.

Method and apparatus for the synchronization of a gear machining

The present invention relates to an apparatus and a process for a gear processing machine operating according to the screw rolling process principle and with positive control of the movement of a rotating tool in the prearranged toothing of the workpiece rotating with respect to the tool.

Apparatus for the control of a tool in a gear processing machine

The present invention relates to a method and apparatus for the production of an additional rotational motion of a helically toothed gear workpiece in an electronically, positively controlled gear processing machine operating according to the hobbing method which has separate rotating drives for workpiece and tool. In this process, a series of impulses are supplied to a controller. These impulses are compared to each other for the production of a control signal for the readjustment of the workpiece drive. The series of impulses are dependent upon the rate of rotation of each of the drives. An additional signal is supplied which is derived from the longitudinal advance of the workpiece in relation to the tool.
