ABSTRACT:
A process for dressing a single or multiple-grooved worm or threaded workpiece by a single or multiple-grooved worm or threaded dressing tool includes the turning of the workpiece and tool with the dressing tool in a comb-type contact with the workpiece. By using an additional axial relative movement between the dressing tool and the workpiece, determined by the radial positioning and return movements, the contact points are displaced such that the desired grinding profile is produced on the workpiece. Since the entire surface area of the instantaneous contact points is significantly smaller than the entire profile area of the workpiece, the cutting forces which occur are relatively small, so that high dressing speeds can be obtained. It is also possible to make various flank corrections on the workpiece. The apparatus for carrying out the process is also disclosed.
