Method for allocation of one or more pipes with several pipe parts to be cut

摘要

The invention relates to a method for allocation of a pipe or several pipes with several pipe parts to be cut for a laser cutting installation, wherein the pipe parts to be cut are selected from an order table. Methods include measuring a length of each of the one or more pipes, calculating, before measuring, a nesting of a pipe part relative to the same pipe part or a different pipe part of the order table, calculating a plurality of pipe allocation variants for a particular pipe of the one or more pipes with the pipe parts to be cut based on the nesting and the measured pipe length of the particular pipe, selecting one of the plurality of calculated pipe allocation variants as a desired pipe allocation, and initiating cutting of the particular pipe based on the desired pipe allocation.

1. A method for allocation of a pipe with several pipe parts to be cut using a laser cutting machine, wherein the pipe parts to be cut are selected from an order table, the method comprising:
prior to cutting any pipe parts from the pipe:
calculating a nesting of a pipe part relative to another pipe part of the several pipe parts, each nesting pipe part comprising an inclined end having an angle other than 90°,measuring, after calculating the nesting, a length of the pipe,calculating a plurality of pipe part allocation variants for the pipe with the pipe parts to be cut based on the calculated nesting and the measured pipe length of the pipe,calculating a sum of pipe parts for each of the plurality of calculated pipe part allocation variants;identifying a subset of calculated pipe part allocation variants as having a same maximum sum of pipe parts;calculating an occupied pipe length for each of the subset of calculated pipe part allocation variants; andselecting one of the plurality of calculated pipe part allocation variants as a desired pipe part allocation, the desired pipe part allocation having the smallest occupied pipe length of the subset of calculated pipe part allocation variants; and cutting pipe parts from the pipe based on the desired pipe part allocation.
