Abstract

A method for producing a force-measuring element (10) having at least one articulation point (20) which separates one region of the force-measuring element (10) into two connected subregions (11, 12) which can be deflected in relation to one another. The method includes: providing a force-measuring element blank (10), removing material from the force-measuring element blank (10) in order to produce the articulation point (20), checking whether the deflection behavior of the subregions (11, 12) which is produced by the articulation point corresponds to a predefined specification, defining a correction form (30) which can be produced through material removal and compensates for an ascertained deviation from the predefined specification, correcting the articulation point geometry using a laser and the previously defined correction form (30), through material removal at the articulation point.
