Embodiment Construction

[0057] In laser cutting it is known to nest workpieces in such a way that the highest possible material utilization is achieved and accordingly the amount of material loss is kept low.

[0058] The concept described here is based in part on the knowledge that such methods do not always minimize cutting costs, since the position of the part relative to the support web may also be of significant relevance to the overall cost. Because, depending on the position of the part on the pallet, wear can occur, for example, at the support webs during piercing, for example. Furthermore, the material-optimized nesting can lead to longer cutting times or loss of quality on the part, for example due to tearing of the cutting gap during critical processes or due to welding or welding shavings flying off. In addition, tilting of the part and collisions of the cutting head with the cutting material may occur.

[0059] The aspects described here are based in part on the knowledge that, in addit...

Abstract

The invention relates to a method (39) for producing a nesting plan (49A) for controlling cutting process of a flat-bed machine tool (1) for cutting out workpieces (9) from a material sheet (7), the nesting plan (49A) comprising an overlap-free arrangement of sub-areas (9A, 9B, ...) corresponding to the workpieces (9) in a two-dimensional planning space (23) and a spatial arrangement of predetermined support areas (27). After each new insertion of a sub-area (9A, 9B, ...) during the nesting, a packing density assessment and at least one assessment (127, 129A-C), incorporating the position data, of the starting position (54) of the newly inserted sub-area (9A, 9B, ...) are performed in a local search area.

Description

technical field [0001] The invention relates to a nesting method for workpieces to be cut by means of a flatbed machine tool, in particular a method for generating a nesting plan for controlling the cutting process of a flatbed machine tool, for example a flatbed laser cutting machine. Background technique [0002] In the sheet metal processing industry, the nesting of workpieces to be cut on raw material plates is part of the production process, wherein this nesting results in a specific layout of the cutting lines. Here, the nested result is also referred to as a nested plan. [0003] In flatbed laser cutting machines, such 2D nesting problems are mainly solved in terms of minimizing the raw material to be used, since raw material usually constitutes a large part of the total cost. However, other aspects also have an impact on the overall costs, such as delays in the cutting process or extended downtime of flatbed machines due to service or repairs. In this context, for ...
