摘要：
The invention relates to a method for laser beam machining a workpiece (15) extending along an axis (A) by means of a device for laser beam machining (1), wherein the device for laser beam machining (1) comprises a laser device (2) which is configured to generate a laser beam (5) made of individual consecutive laser light pulses (5a, 5b, 5c), a beam deflection unit (9), which is configured to deflect the laser beam (5) onto a surface (15a) of the workpiece (15) and move the laser beam on the surface (15a) along the axis (15), and a drive (16) for continuously rotating the workpiece (15) about the axis (A) in a direction of rotation (U) at a rotational speed, wherein, for the purpose of laser beam machining the workpiece (15), the workpiece (15) is made to carry out a continuous rotation about the rotary axis (A) in the direction of rotation (U) by means of the drive (16), and the laser beam (5) is deflected onto the surface (15a) of the workpiece (15) by means of the beam deflection unit (9) and is moved on the surface (15a) along the axis (A), wherein material of the workpiece (15) is ablated by means of laser light pulses (15a, 15c), and wherein the laser device (2) is synchronized with the beam deflection unit (9) and the drive (16) in such a way that the respective laser light pulse (15a, 15c) impinges on the surface (15a) at a desired impingement point (15b) of the surface (15a) of the workpiece (15a).L'invention concerne un procédé d'usinage par faisceau laser d'une pièce (15) le long d'un axe (A) au moyen d'un dispositif d'usinage par faisceau laser (1), lequel comprend un dispositif laser (2) configuré pour générer un faisceau laser (5) constitué d'impulsions de lumière laser individuelles consécutives (5a, 5b, 5c), une unité de déviation de faisceau (9), configurée pour dévier le faisceau laser (5) sur la surface (15a) de la pièce (15) le long de l'axe (A), et un arbre d'entraînement (16) pour maintenir la pièce (15) en rotation continue autour de l'axe (A)
