ABSTRACT:
A method for the precision working of the tooth flanks of gear-shaped workpieces with an abrasive internally toothed tool wherein the tool, after each workpiece or after several workpieces, is dressed in the same mounting with a dressing wheel, the tooth system of which corresponds with the one of the gear-shaped workpiece and the tooth flanks of which are covered with extremely hard grinding granules. To improve the tool geometry the dressing of the internally toothed tool is done with a one-flank or a two-flank contact between the dressing wheel and the internally toothed tool and with an electronic forced guiding of the rolling and relative movements between the dressing wheel and the internally toothed tool, and, the precision working in the free or in the torque guided two-flank engagement between the internally toothed tool and the workpiece.
