Abstract
In a hobbing machine for producing a gear from a workpiece, a device for controlling the rate of rotation of the workpiece in accordance with the motion of a cutting tool compensates for a lag in a feedback loop servo control and concomitantly in the rotation of the workpiece. The device calculates a correction quantity from the actual velocity of the tool and the loop gain of the feedback loop servo control and feeds the correction quantity thereto.
