Claim Text:
1. A device ( 1 ) for marking parts by percussion comprising: a mobile punch ( 3 ) to strike a part ( 2 ) to be marked so as to deliberately plastically deform said part ( 2 ), an impact detector ( 4 ) for detecting impact of the punch ( 3 ) on said part ( 2 ) to be marked, and a processor ( 5 ) functionally connected to the impact detector ( 4 ) to evaluate the time between the impact time (t i ) and a predetermined origin time (t 0 ) before the impact time (t i ), and further comprising a propulsion device ( 6 ) adapted, when activated, to cause the punch ( 3 ) to move, and wherein the processor ( 5 ) is capable of evaluating a flight time (Δt) between the time of activation of said propulsion device ( 6 ) and the time at which the punch ( 3 ) collides with the part ( 2 ), wherein the propulsion device ( wherein the impact detector (
