Patent ID: 7467577

Claim:
A method for producing a thread in a workpiece, comprising the steps: a) producing a preliminary thread in the workpiece in at least one first working step by removing material from the workpiece with a cutting action, wherein a preliminary thread profile is produced having two preliminary thread flanks and a preliminary thread root connecting the two preliminary thread flanks; and b) producing a final thread having a final thread profile, the final thread profile having two final thread flanks and a final thread root connecting the two final thread flanks, wherein the final thread is produced in at least one second working step by plastic pressing-in of the material of the workpiece at least in a section of the preliminary thread profile by a predetermined pressing-in volume using at least one thread-forming profile, the at least one thread-forming profile having two flanks and a root region connecting the two flanks; c) wherein at least one of the preliminary thread flanks is inclined at least in a flank section at a first inclination angle to a center axis of the preliminary thread profile, and wherein at least one of the flanks of the thread-forming profile is inclined at least in a flank section at a second inclination angle to a center axis of the thread-forming profile; d) wherein the first inclination angle and the second inclination angle are different from one another.
