1. Corner melting
When cutting corners of thin steel plates at a reduced speed, the laser will melt the corners due to overheating. Generate a small radius at the corner 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. When cutting corners, sharp corners and small graphics, it is easy to burn edges, which affects the cutting quality.
3. Leader settings
In the process of cutting thick plates, in order to make the cutting seam connect well and prevent the beginning and end burns, a transition line is often introduced at the beginning and end of the cutting, which are called lead line and tail line 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, pay attention not to set the lead wire at sharp corners and other places that are not easy to dissipate heat. The connection between the lead and the slit shall 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 kinds of parts are combined into a combination, and a large number of regular graphics should 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 production efficiency, many laser cutting equipment operate continuously for 24 hours, and use unmanned automatic loading / unloading devices to hit the overturned parts after cutting, causing damage to the cutting head and production interruption, resulting in great losses. This requires attention when sorting:
① Select the appropriate cutting path and bypass the cut parts to reduce the collision.
② Choose the best cutting route and 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. Disposal of surplus materials
After cutting the parts, the skeleton like residual material on the workbench of the laser cutting equipment needs to be removed as soon as possible to facilitate subsequent cutting operations. For laser cutting equipment without automatic unloading device, the skeleton shaped residual material can be cut into small pieces to facilitate rapid removal. Thus, the personal injury caused by the heavy and sharp edge residual materials handled by the operator is avoided.
