Abstract: Method for making tools for machines adapted for forming threads on cylindrical bodies by means of plastic deformation, which provides for arranging a hollow tubular support body (2B) made of metal material facing the work head of an apparatus of laser cladding type and provided with a laser beam emitter and with a nozzle for emitting a flow of metal powders. The method provides for the controlled advancing of the work head along the longitudinal extension (Y) of the tubular support body (2B) for a plurality of longitudinal strokes and the controlled rotation of the tubular support body (2B) with respect to the work head for a plurality of rotations. There is then the controlled deposit of the coating bead (5) on the peripheral surface of the tubular support body (2B) and then the forming of a thread with excess material with respect to the profile of the thread to be made by means of the aforesaid controlled deposit of a plurality of adjacent beads during the combination of the controlled advancing of the work head and the controlled rotation of the tubular support body (2B). Finally, a step is provided for grinding the excess thread by means of removal of material which is outside the programmed profile of the thread.
