Before using the laser cutting machine, we will import the prepared drawings into the program, and then use the typesetting software to arrange the patterns on a single board, so that the laser cutting machine can batch process the products. Among them, although the typesetting process is very short, there is a lot of knowledge hidden in it, and the layout is slightly wrong, which will have a great impact on the cutting effect of the whole board.
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 created at the corner to keep the laser cut at high speed, avoiding overheating and melting of the steel sheet when cutting corners, thus achieving good cutting quality, reducing cutting time and increasing productivity.
2. Part spacing
Under normal circumstances, the thick plate and the hot plate are cut, and the spacing between the parts is large, because the heat of the thick plate hot plate has a large influence, and when cutting the corners and the small figure, it is easy to burn the edge and affect the cutting quality.
3. Lead set
In the process of cutting thicker plates, in order to make the kerfs well connected and prevent burns at the beginning and end points, a transition line is often introduced at the beginning and end of the cutting, respectively called the lead and the tail. The lead and the tail are the workpiece itself. It is useless, so it should be arranged outside the range of the workpiece, and at the same time, be careful not to set the lead at a sharp corner and other places where it is difficult to dissipate heat. The connection between the lead and the slit is as far as possible using a circular arc transition to make the machine move smoothly and avoid burns caused by the corner stop.
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 production efficiency, many laser cutting equipments operate continuously for 24 hours, and use unmanned automated loading/unloading devices to hit the cut over parts and cause cutting head damage and production interruption. Great loss. This requires attention when sorting:
(1) Select the appropriate cutting path, bypass the cut parts, and reduce the collision.
(2) Choose the best cutting route and reduce the cutting time.
(3) Automatically or manually combine multiple small parts with tiny connections. After cutting, the removed parts can easily disconnect the tiny connections.
6. Residual material processing
After cutting the parts, the skeleton-like residual material on the laser cutting equipment table needs to be removed as soon as possible to facilitate subsequent cutting operations. For laser cutting equipment that does not have an automatic unloading device, the skeleton-like residual material can be cut into small pieces for quick removal. Thereby avoiding the operation.
