Abstract
A method for the precision working of gears, particularly by a gear shaving process. The method involves the step of changing the direction of rotation between the workpiece and the tool approximately starting with half of the advance path and the smallest distance between the axes. The optimum condition occurs when the direction of rotation is changed prior to reaching the smallest distance between the axes and the advance is directed at a right angle with respect to the axis of the workpiece or tool. The tool is rotatably supported on a spindle as is the workpiece. The workpiece is driven relative to the tool to advance same relative to the tool. Control devices are provided for controlling the movement of the workpiece relative to the tool. The tool has grooves which extend from the addendum to the dedendum and form cutting edges and the flanks of the teeth have concaved surfaces.
