METHOD FOR PRODUCING A WORKPIECE SURFACE ON A BAR-SHAPED WORKPIECE

Producing a workpiece surface at a rod-shaped workpiece (11) using a processing machine (10) comprising a laser (12) with a laser head (13) and a machine drive device (16), comprises (a) positioning and/or aligning the workpiece relative to the laser head, (b) presetting and/or selecting an outer contour of the pulse surface and incidence position, (c) discharging the laser pulses over the laser head in an emission direction to the workpiece to the predetermined incidence position within the pulse surface, and (d) moving the laser head and/or the workpiece relative to each other. Producing a workpiece surface at a rod-shaped workpiece (11) using a processing machine (10) comprising a laser (12) for producing laser beam pulses with a laser head (13) for directing the laser beam pulses of the laser to the workpiece and a machine drive device (16) comprising at least one machine axle drive, which is designed for moving the workpiece and the laser head into at least one translational and/or rotational degree of freedom relative to each other, comprises (a) positioning and/or aligning the workpiece relative to the laser head, (b) presetting and/or selecting an outer contour of the pulse surface and incidence position, which is spaced from each other and arranged within the pulse surface, (c) discharging the laser pulses over the laser head in an emission direction to the workpiece to the predetermined incidence position within the pulse surface, and (d) moving the laser head and/or the workpiece relative to each other such that the pulse surface is completely moved in the emission direction to a predetermined movement path with respect to the workpiece for producing the workpiece surface. The laser beam pulses are discharged from the laser head to an incidence position in a predetermined sequence. The laser pulses are tangentially aligned to the section of the workpiece surface generated during processing of the workpiece. The section of the workpiece surface is adjacent to the pulse surface. The material removal is carried out on the pulse surface. An independent claim is also included for producing a sharp edge at an edge of a workpiece surface of the workpiece, comprising producing a surface on the workpiece, where the surface has excess mass at least around the edge, and the excess mass is removed by the above mentioned method.
