The metal industry is one of the most important application markets for laser processing, and the competition in China's sheet metal market is going to shift toward competition for high-quality and high-tech products. Moreover, the metal industry is one of the most important application markets for laser processing. Because of this, the transformation of processing technology is required if it is to be brought into conformity with the development trend of the international market. This is something that cannot be avoided. Then, in the course of the process of processing sheet metal, what different kinds of obstacles will be presented themselves?

Methods that involve cutting and punching holes in something. Any method of thermal cutting, with a few notable exceptions here and there where it can start from the edge of the sheet, will generally involve making a small hole in the sheet. These exceptions can be found here and there. These are extremely unusual exceptions. In general, when the surface cutting fracture of the designed part does not require roughness, laser cutting programming can avoid the need for manual processing. This enables the control software to automatically generate the puncture point at the appropriate location. However, this issue should be taken into consideration when the design has higher roughness requirements for the cut portion of the part that is being machined, which typically alloy die casting company requires agitation. This is due to the fact that there must be agitation. The manual control of the puncture point in the photocutting process involves manually adjusting the starting position of the laser beam. This is done in order to achieve the desired result. The manual control of the puncture point is another name for this aspect of the process.

The process of cutting a profile with a laser beam begins with the creation of this hole, which performs a function comparable to that of the perforation produced by cutting wire. The majority of the time, the path that the laser beam takes along its trajectory is oriented in a manner that is perpendicular to the tangent direction of the cutting profile of the component that is being processed. As a direct consequence of this, the diameter of the perforations is not particularly large, and the quality of the perforations is quite good. The process of pulse perforation, which involves melting or vaporizing a small portion of the material, is carried out with the assistance of a pulse laser with a high peak power. When holes appear as a result of exothermic oxidation, it is common practice to use air or nitrogen as an auxiliary gas in order to fill them in. This is done in order to prevent the holes from becoming larger. During the process of cutting, the pressure of the gas being used is lower than the pressure of the oxygen being used. In order to achieve the level of surface accuracy that is required for the components that are currently being processed, it is necessary to relocate the laser program's generated puncture point to the required reasonable position.

This is done in order to accomplish this goal. In addition, pulse perforation calls for the utilization of a reliable gas circuit control system in order to accomplish the switching of gas types in addition to the regulation of gas pressure and the perforation duration. This is because pulse perforation requires a longer period of time for the hole to be created.

Getting rid of the burr that was left on the workpiece made of low-carbon steel after it was cut by laserAccording to the working principle and design principle of co2 laser cutting, it is analyzed that the laser focus position is incorrect, and it needs to be detected and adjusted according to the focus offset; the laser output power is insufficient. This is because the laser focus position is incorrect, and it needs to be detected and adjusted according to the focus offset. This is because the position of the laser focus is incorrect, and it needs to be detected and adjusted according to the focus offset in order to fix the problem. As a result of this, it is of the utmost importance to ascertain whether or not the laser generator is functioning in the standard condition. If it is normal, check to see if the output alloy die casting company value of the laser control button is accurate and adjust it; the cutting line speed is too slow, and it needs to be increased in the operation control; the cutting gas purity is insufficient, and high-quality cutting working gas needs to be provided; the laser focal length deviation needs to be adjusted according to the focal length in order to carry out testing; the cutting gas purity is insufficient; the cutting line speed is not sufficient; the laser focal length deviation needs to be adjusted according to the focalAdjust the offset as necessary; after being on for an extended period of time, the machine will become unstable and will need to be turned off before it can be restarted.



In the event that all of the other parameters are found to be within the normal range, the following cases should be evaluated in order to establish whether or not the nozzle of the laser head needs to be replaced. As a consequence of this, careful consideration ought to be given to this aspect when one is chopping and processing components with a laser. At this point in time, it is necessary to consider other aspects of the machine tool in a comprehensive manner. For example, it is necessary to determine whether or not the nozzle needs to be replaced, as well as whether or not the movement of the guide rail is unstable, etc. The findings gleaned from the field trials suggest that the third strategy is the one that delivers the most satisfactory outcomes. On the other hand, a laser cutting machine with a lower power should use pulse punching to obtain a better surface finish. Furthermore, once the perforation is complete, the machine should immediately use oxygen rather than auxiliary gas for cutting, as this will ensure the best possible results. This is due to the fact that oxygen possesses a greater molecular weight than auxiliary gas.

As a consequence of this, the laser that is utilized must not only have a high output power but also have the spatiotemporal characteristics of the beam; as a consequence of this, the requirements for laser cutting cannot be satisfied by a standard cross-flow co2 laser.

The process of determining where the laser will cut during the process of laser cutting. During the process of the material being processed, a continuous laser will irradiate the material to create a pit in the middle of the material, and then the working gas flow that is coaxial with the laser will quickly remove the molten material from the pit. Make a hole in the beam. The laser beam that is utilized by the fiber laser cutting machine functions according to this basic principle of operation. Workpiece fabricated by laser cutting of stainless steel and aluminum-zinc plateburr analysis of the situation CNC machining described above, first take into consideration the burr factor when cutting low carbon steel. Increasing the cutting speed, on the other hand, is not the answer because there is a possibility that the plate will be cut without any wear occurring if the cutting speed is increased. This is true in many aspects of metalworking, but it is especially true in the galvanizing of sheet metal.

Modifying the pulse width, pulse frequency, both pulse width and frequency at the same time, or all three of these parameters at the same time is a more practical way to adjust the average laser power in industrial production. In the past, punch holes would first be punched out on a laser punching compound machine, and then they would be cut with a laser after being prepared for cutting. Following that, the holes were made using a punch. Because of the sudden change in the vector direction that takes place whenever the laser beam moves in a short amount of time, a rough cut surface of this kind will flow downward along the section of the processed material that was cut. The primary reason for this is because the laser beam moves in a short amount of time. When cutting low-carbon steel, how to handle sparks that aren't the norm during the cutting processThe flatness quality of the cut section will suffer as a result of this circumstance, which will cause it to be compromised. You need to put an immediate stop to the cutting process right now, check the connection status of the laser head, and then re-thread the material.

If the nozzle is not replaced with a new one, the cutting air pressure needs to be increased, and the thread at the connection between the nozzle and the laser head needs to be loosened. These steps need to be taken in order for the laser head to continue functioning properly.
