Nesting for fiber laser cutting machine
Nesting for fiber laser cutting machine.
Before using the laser cutting machine, we will import the drawings into the program, and then use the typesetting software to arrange the graphics on a single board. So that the laser cutting machine can batch process the products. Among them, although the typesetting process is very short.We need know rules about nesting.
1, corner melting
When the corner of the thin steel sheet is decelerated, the laser melts the corner due to overheating. A small radius is generated at the corner to keep the laser cut at a high speed, avoiding the phenomenon of overheating and melting of the steel sheet when cutting the corner, thereby achieving good cutting quality, reducing cutting time and improving manufacturing force.
2, part spacing
Usually, the thick plate and the hot plate are cut, and the spacing between the parts is large. Since the heat of the thick plate hot plate is greatly affect, when cutting the corner corners and small patterns, it is easy to burn the edges and affect the cutting quality.
3, lead setting
In the process of cutting thicker plates, in order to make the kerfs well connecting and prevent burns at the beginning and end points, a transition line often introduce at the beginning and end of the cutting, respectively call the lead and the tail. The lead and the tail are the work piece itself. It is useless, so it should place outside the scope of the work piece. At the same time, be careful not to place the lead on a sharp corner or other places where it is difficult to dissipate heat. The connection between the lead and the kerf is as close as possible to the arc transition, so that the mechanical movement is smooth and the burn caused by the corner stop is avoided.
4, common edge cutting
Combine two or more parts into one combination, and the large-scale regular graphics should be as common as possible. The common edge cutting can greatly shorten the cutting time and save raw materials.
5, part collision
In order to maximize manufacturing efficiency, many laser cutting machines are continuously running for 24 hours, and use unmanned automatic loading/unloading devices to hit the cut-out parts and cause cutting head damage and manufacturing interruption. Great loss. Pay attention when you need to sort:
a. Choose the appropriate cutting path, bypass the cut parts, and reduce the collision.
b. Choose the best cutting route to reduce cutting time.
c. Automatically or manually combine multiple small parts with tiny connections. After cutting, the removed parts can easily disconnect the tiny connections.
