Problems solved by technology

[0019] All in all, the known method of segmenting workpieces with laser beams has reasonable rigor within each segment, and the processing traces at segment boundaries can be blurred to a certain extent, but the following may occur at the boundaries of adjacent segments. Discontinuities in the form of geometric, joining, or ablative errors that are optically identifiable and / or present a functional discontinuity

Embodiment Construction

[0056] Generally, the features in this specification should be considered to be combinable with each other, even if such a combination is not explicitly mentioned, as long as the combination is technically feasible. Descriptions of method steps and methods are also to be understood as descriptions of device components and device or device components and devices for carrying out the corresponding method steps or methods, and vice versa.

[0057] Generally, in this specification, use such as figure 1 The coordinate system shown. Its z direction is the vertical direction and may be the depth direction of the depression, while the x and y coordinates are horizontal. This is to be understood for illustrative purposes. Due to the various axes of rotation and complex geometries in practice, it cannot usually be assumed, for example, that the (instantaneous or original) workpiece surface lies in the x-y plane or that the recess depth direction is always vertical.

Abstract

The invention relates to a method for machining a workpiece by means of a pulsed laser beam emitted from a tool head, wherein the pulsed laser beam is guided across the surface of the workpiece at a constant relative position between the workpiece and the tool head , the workpiece can be continuously machined at the first and another second relative position. The operating parameters at the second relative position are controlled such that the one or more laser pulses produced at the second relative position hit positions relative to the one or more laser pulses produced at the first relative position Each laser pulse hit position has a predetermined position, especially in a one-dimensional or two-dimensional grid defined by the plurality of laser pulse hit positions generated by the first relative position on the workpiece surface.

Description

technical field [0001] The invention according to the preambles of the independent claims relates to a machining method for machining a workpiece by means of a laser beam, as well as to a laser tool, a laser machining machine and a machine control. Background technique [0002] Prior art, among others, is DE 1017322A, WO2000 / 18535, DE 10324439A, DE10352402A, DE102004013475A, EP1613447A1, DE1021007012816, DE102007012815A, DE102007016056A. [0003] figure 1 A known machine tool 1 is schematically shown. The machine 1 comprises a frame 16 . Adjustably mounted thereon is a workpiece table 14 which holds a workpiece 11 firmly mounted thereon during operation. The adjustability of the workpiece table 14 relative to the frame 16 may be translational and / or rotational along and / or about one or more translational and / or rotational axes. These axes are indicated by 15 in the figure. A laser cutter head 13 is also installed on the machine frame 16 . It may be exchanged, inserted ...
