In the process of laser cutting metal plate, sometimes the heat change of the object to be cut will form the falling of the processed parts, which will make the end of the processing warped. The raised end will contact the machining head or nozzle again. If the machine continues to run when the machining head or nozzle is in contact with the object to be processed, it is easy to cause the deformation of the nozzle of the laser equipment or the damage of the machining head

Three solutions to the problem of material warping

Scheme I: regional avoidance

We can avoid the running track generated by the metal cutting software. Whether it's a part or a scrap, if its outer surrounding dimension is within the range of 12-100 mm, the laser head will walk in the path of 20 mm outside the contour, and will not pass through this area. If we want to pass through this area, we must lift the laser head up to walk, avoiding the problem of collision due to warping. No Yes, if the layout of parts on the plate is very dense, and the outer surrounding dimension of this part is relatively small, then it may not be avoided.

At this time, we need to combine the second and third solutions described below to deal with it. In addition, the method of regional avoidance has the advantage of effectively avoiding the collision between the laser head and the blank part of the plate (after the waste is cut, it falls into the waste box under the workbench, and the blank part is formed on the plate), because the red spot of the laser head is always on the plate.

If you go to the blank, the red dot will come under the workbench, the laser head will collide with the plate, and the metal cutting software must avoid the path on the plate, so fundamentally avoid the occurrence of this danger.

Scheme 2: add micro connection point

Metal cutting software can add single or multiple micro connection points for parts or scraps when adding laser tool path. The purpose of adding micro connection points is to connect the cut parts or scraps with plates through the way of contact points, so as to effectively solve the warping of parts or scraps after cutting.

Scheme 3: waste cutting

This scheme only aims at the waste generated when the metal cutting software is cutting, because the waste is unnecessary, it can be broken down, and the broken waste can fall into the waste box under the workbench of the laser cutting machine tool, thus fundamentally solving the problem of waste upwarping. The distance between the laser paths for cutting waste materials can be set in the part waste cutting
