1. Corner melting
When cutting the corners of thin steel plates at a reduced speed, the laser will melt the corners due to overheating. A small radius will be generated at the corners to maintain the high-speed laser cutting and avoid overheating and melting of steel plates when cutting corners, so as to obtain good cutting quality, reduce cutting time and improve productivity.
2. Part 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 impact, it is easy to burn edges when cutting sharp corners and small graphics, which will affect the cutting quality.
3. Leader settings
In the process of cutting thick plates, in order to ensure good connection of cutting seams and prevent burns at the beginning and end, a transition line is often introduced at the beginning and end of cutting, which are called lead and tail lines respectively. The lead and tail lines are useless to the workpiece itself.
Therefore, it should be arranged outside the scope of the workpiece. At the same time, it should be noted that the lead should not be set at sharp corners and other places that are not easy to dissipate heat. The connection between the lead and the slit should adopt arc transition as far as possible to make the machine move smoothly and avoid burns caused by corner pause.
4. Common edge cutting
Two or more types of parts shall be combined into a combination, and a large number of regular graphics shall share the same edge as much as possible. Common edge cutting can greatly shorten the cutting time and save raw materials.
5. Part collision
In order to maximize the production efficiency, many laser cutting equipment operate continuously for 24 hours, and use the unmanned automatic loading / unloading device to hit the overturned parts after cutting, resulting in damage to the cutting head and production interruption, resulting in large losses.
This requires attention when sorting:
① Select the appropriate cutting path, bypass the cut parts, and reduce the collision.
② Select the best cutting route to reduce cutting time.
③ Automatically or manually combine several small parts with micro connections. After cutting, the removed parts can easily disconnect the micro connections.
6. Residual material treatment
After cutting the parts, the skeleton shaped residual materials on the workbench of the laser cutting equipment need to be removed as soon as possible to facilitate subsequent cutting operations. For the laser cutting equipment without an automatic unloading device, the skeleton shaped residual materials can be cut into small pieces to facilitate rapid removal, so as to avoid personal injury caused by the operator moving the heavy and sharp edge residual materials.
