Abstract
A method of piercing sheets and thin sheets using high-energy rays (such as laser or electronic rays), the beam presenting at the point of incidence a round or slightly elliptical cross section, and the pulsing beam possessing an energy density such that the workpiece is drilled with an impulse at the point of incidence of the ray, by evaporation of the material, characterized in that by means of relative movement of the ray and the workpiece, a path (t) is traveled between two consecutive impulses that is smaller than the diameter (d) of the hole, whereby the individual perforations fit together in such a way that a gap is obtained with n impulses, the length of which is determined according to 1 = (n-1) .t + d, and because once the desired length (1) of the slit has been reached, the succession of pulses is interrupted until, due to continuing to maintain relative movement, the desired distance (a) is achieved between two slits uras, the magnitude a + d having to be an integer multiple of the pitch (t) of the holes.
