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 board, so that the laser cutting machine can process the products in batches. Among them, although the typesetting process is very short, there is a lot of knowledge hidden in it. If the typesetting is slightly wrong, it will have a great impact on the cutting effect of the whole board. So, here’s a list of six matters needing attention in typesetting.
1. Corner melting
When cutting the corner of the thin steel plate at a reduced speed, the laser will melt the corner due to overheating. Generate a small radius at the corner to maintain the high-speed cutting of the laser, avoid overheating and melting of the steel plate when cutting the corner, thereby obtaining good cutting quality, reducing cutting time and improving productivity.
2. Parts spacing
In general, when cutting thick plates and hot plates, the spacing between parts should be large, because the heat of thick plates and hot plates has a great influence. When cutting sharp corners and small figures, it is easy to burn edges and affect the cutting quality.
3. Lead wire setting
In the process of cutting thicker plates, in order to make the slits connect well and prevent burns at the beginning and end, a transition line is often led at the beginning and end of cutting, which is called lead wire and tail wire respectively. The lead wire and tail wire are useless to the workpiece itself, so they should be arranged outside the scope of the workpiece. At the same time, care should not be taken to set the lead wire at sharp corners and other places that are not easy to dissipate heat. The connection between the lead wire and the slit shall adopt the arc transition as far as possible to make the machine move smoothly and avoid the burn caused by the corner stop.
4. Common edge cutting
The common edge of two or more parts into a combination, a large number of regular graphics as far as possible common edge, common edge cutting can greatly shorten the cutting time, but also save raw materials.
5. Part collision
In order to maximize the production efficiency, many laser cutting equipment is 24h continuous operation, and the use of unmanned automatic loading/unloading device, hit the cutting completion of the tipping parts and cause damage to the cutting head and production interruption, resulting in greater losses. This requires attention when sorting:
① Select the appropriate cutting path and bypass the cut parts to reduce collisions.
Choose the best cutting route to reduce the cutting time.
③ Automatically or manually combine multiple small parts with small connections. After cutting, the removed parts can easily disconnect the small connections.
6. Residual material treatment
After cutting the parts, the skeleton-like residual material on the worktable of the laser cutting equipment needs to be removed as soon as possible to facilitate subsequent cutting operations. For laser cutting equipment that does not have an automatic discharge device, the skeleton-like residual material can be cut into small pieces to facilitate rapid removal. So as to avoid the operator because of moving heavy and sharp edge of the residual material caused by personal injury.
