Abstract:
Method for the profiling of single-start or multistart grinding worms, in which a disk-shaped profiling tool executes a repeated shifting movement along a rotating grinding worm and is positioned suitably to create worm thread height modifications, characterized in that in grinding worm thread axial section areas in which there is no shape modification or only a depth-crown shape modification of the profile, profiling is carried out in the profile dressing method with line contacts, and in flank areas that have shape modifications as well as in the root, tip and tip chamfer areas of a worm thread axial section, profiling is carried out in the line-by-line dressing method with punctiform contact, whereby each of the two flank sides of a grinding worm thread axial section is divided into individual shape elements for this purpose.
