With the widespread use of fiber laser cutting machines, cutting quality problems will inevitably occur during operation. Today we will analyze a cutting problem: discontinuous cutting.

First of all, let's take a look at the reasons for this cutting quality problem:

1. The editing of the operating program is unreasonable.

Unreasonable programming may result in discontinuous sheet cutting. In the process of cutting the plate, the cutting head is very close to the surface of the workpiece. When the fiber laser cutting machine cuts multiple parts of the steel plate, the laser program defaults to scribing and then cutting to avoid the collision of the cutting head. Unnecessary damage to the machine. If the closed area is not closed when the laser program is compiled, the partial steel plate is connected to the whole after cutting, and manual cutting will easily damage the plate and cause scrap;

2. The ventilation of the auxiliary gas during the cutting process will also lead to discontinuous cutting.

During the processing of the fiber laser cutting machine, the auxiliary gas mainly blows the molten metal out of the slit. When the auxiliary gas is used up, the equipment will automatically stop moving, and the gas will be more

So how to avoid cutting discontinuity, let's analyze the specific problems and find out the methods and methods for the reasons.

1. For the discontinuous cutting caused by programming errors, the operating engineer is required to have high professional quality, and should be carefully checked in the process of compiling the cutting program to avoid mistakes;

2. For the discontinuous cutting problem caused by the replacement of auxiliary gas, after the accumulation of actual operation experience, when replacing the gas bottle and re-cutting, we should reduce the cutting speed to 5% of the normal cutting speed, press the start key and Speed up key to continue cutting;

3. When the fiber laser cutting machine suddenly stops and restarts during the working process, the interface of the cutting point will also be discontinuous. Therefore, in actual work, it is necessary to strictly follow the operation instructions to avoid the cutting machine from stopping due to wrong operations. Generally, the replacement is completed. Then continue to cut, so that the cutting trajectory is slightly different from the trajectory when parking, resulting in discontinuity of the cutting trajectory. Powerful manufacturers will provide professional training after selling the machine.
