A process for the preparation of at least one clamping slot, and at least one cutting edge and the laser machining apparatus

摘要

A process for the preparation of at least one groove (61) and at least one cutting edge (60) on a blank (27), comprising the steps of:– Providing the blank (27),– Generating pulses (24)– repeated directing the laser beam pulses (24) onto spaced predetermined points of impact (25) along a predetermined pulse web (b) by means of a deflector means (23) within a predetermined for switching (55) on the blank (27),– Performing a relative movement (v) between the blank (27) and for switching (55) by means of a positioning device (30), about the at least one clamping slot (61) and the at least one cutting edge (60) on the blank (27), wherein material in a plurality of layers by the for switching (55) specific removal of material layers (59) is removed,– wherein initially the at least one clamping slot (61) in the blank (27) is produced before the at least one cutting edge (60) on an outer side (70) of the blank (27) is generated, and an intensity of the laser beam pulses (24) for the generation of the at least one cutting edge (60) is smaller than that for the generation of the at least one groove (61).
