A Nesting Path Optimization Method Applied to Co-edge Cutting of Pipe Parts

Abstract

The invention provides a material sleeve path optimization method applied to common edge cutting of pipe parts. On the premise that machine tool equipment, the pipe raw material and machined parts arenot changed, the cutting path is optimized, so that the purpose that the raw material of the pipe is saved, the energy consumption of the laser is reduced, the gas consumption is assisted, and the total movement path of the machine tool is reduced is achieved, and meanwhile, the method has positive significance for improving the cross section quality of part products and prolonging the service life of equipment.

Description

technical field [0001] The invention relates to the field of nesting of pipe laser processing parts, in particular to a nesting path optimization method for common-edge cutting of pipe parts. Background technique [0002] Laser pipe cutting machine is a special equipment for cutting, welding, marking, engraving, surface treatment, fine processing and other processes of pipes by using high-energy laser beams. In the laser cutting processing industry, most of them need to use automatic nesting software. After nesting the parts on the set pipe, the processing code is output for processing. In most cases, nesting software can basically get better nesting results, that is, to nest as many parts as possible on limited materials, but the processing path is not necessarily optimal, especially the part-to-part The cutting path is not optimal, resulting in long cutting path and high equipment loss. Therefore, how to optimize the cutting path between parts during nesting, to achieve h...

Problems solved by technology

However, there is no way to deal with multiple notches and the notches are variable. In addition, in the case of geometric compensation in bevel cutting, general nesting does not support co-edge cutting. Parts need to be cut at least twice to truncate

Without an optimized cutting path, on the one hand, the cutting path is long, the equipment loss is large, the efficiency is low, and the production capacity is seriously affected; on the other hand, after repeated processing at the joints of the parts, the pipe will be overheated and the processing effect will be poor

Finally, the inability to share edges will lead to cutting excess material, which will cause waste of pipe raw materials
