What is common edge cutting? what is the benefit?

To give full play to the effectiveness of CNC laser cutting machine tools, it is necessary to use typesetting software and laser cutting automatic programming software. The purpose of typesetting software is to arrange as many parts as possible on a board of a given size or arrange the given parts on a board as small as possible, thereby improving material utilization.

The typesetting software fully considers the efficiency of the subsequent cutting machine tool, and will adopt coedge nesting to realize coedge cutting. Co-edge cutting is to arrange the parts with long sides as long as possible in the way of long side to long side according to certain rules when optimizing the layout. When generating the cutting command, the common side part of the outer contour of these parts is only cut once. . Common edge cutting is an important measure to improve cutting efficiency and save cutting costs.

The most common laser cutting machine tool in actual production generally has only one laser cutting head, which is a cutting nozzle. According to the actual cutting process, the problem that the common edge cutting is solved by path planning is that no matter what the path sequence is, the common edge of all parts is only cut once by the nozzle, and no edges are cut repeatedly. This is because once the plate is cut, thermal deformation and movement will occur, and repeated cutting will affect the quality of the processed section.

The cutting problem after the regular and irregular parts are nested together has always been a concern of laser cutting machine users. The laser cutting process must fully consider the satisfaction of processing quality, processing efficiency and manufacturing costs; the stroke planning of co-edge cutting must follow the principles of minimum punching points and shortest cutting empty strokes, so that cutting efficiency can be greatly improved and cutting costs can be saved. .
