Fiber laser cutting processing as the 21st century advanced manufacturing technology, is more and more widely used in the world now. Because of its high-speed working, nice cutting performance, long lifetime and low maintenance cost.

 

While, during the regular using. We could also optimize the cutting effect, base on the more professional technical knowledge and working experiences. Now Morn Technology would like to share some optimize methods with you.

 

Laser cutting surface roughness mainly depends on the following three aspects:
1. The inherent parameters of the cutting system, such as spot mode, focal length, etc .;
2. Cutting process can adjust the process parameters, such as power size, cutting speed, auxiliary gas type and pressure;
3. Physical properties of processing materials, such as the absorption rate of laser, melting point, melting metal oxide viscosity coefficient, metal oxide surface tension.

 

In addition, the thickness of the workpiece also has a great impact on the quality of the laser cutting edge performance. In contrast, the smaller the thickness of the metal workpiece, the higher the cutting surface roughness level.

To obtain a better surface quality level, the laser power, cutting speed and other process parameters must be optimized several times. In general, for materials with the same characteristics and thickness, the process parameters have a set of optimal cutting process parameters. Will also yield a different incision surface quality. The melting point of the metallic material is low, the thermal conductivity is large, the viscosity coefficient of the melt is small, the surface tension of the metal oxide is small, and the surface quality is easy to be obtained when the laser is cut. Laser cutting of the plate, easy to measure the surface quality, but in the fine processing or cutting some of the complex patterns, it is difficult to directly measure it, only by optimizing the test parameters to control the surface quality. Therefore, in order to facilitate the realization of automated cutting, should establish the external optimization parameters and surface quality level of the corresponding relationship.
