Impact Of Heat Affected Area On Cutting Quality

What is a heat affected area? During the machining process, heating is applied along the area near the laser cut, causing a certain change in the structure of the metal, which can lead to the hardening of the metal. The presence of heat affected zones is not conducive to laser cutting, especially for the smoothness of the surface and edges of sheet metal parts, which can have a negative impact on the surface and edges of sheet metal parts. The heat affected zone not only causes metal hardening, but also leads to dents and corrosion at the metal edges, which may result in errors during actual processing. For laser cutting machines, especially in the process of precision machining, subtle changes can lead to errors in the accuracy of sheet metal parts, directly affecting the processing quality.



The surface roughness of laser cutting is mainly caused by the following three reasons:

1. The inherent parameters of the cutting system, such as spot mode, focal length, etc.

2. The process parameters during the cutting process can be adjusted, such as power, cutting speed, auxiliary gas type, pressure, etc.

3. Physical parameters of processed materials, such as laser absorption rate, melting point, viscosity coefficient of molten metal oxides, surface tension of metal oxides, etc.

In addition, the thickness of the workpiece also has a significant impact on the surface quality of laser cutting. Relatively speaking, the thinner the metal workpiece, the higher the roughness level of the cutting surface. Therefore, choosing a suitable laser cutting machine has a positive effect on improving production efficiency.
