Before buying a laser cutting machine, many companies want to know the quality of the laser cutting machine they buy. This requires everyone to check the quality of the laser cutting machine before choosing the laser cutting machine. Then how to check the quality of the laser cutting machine What about the quality? Let's take a look together. The quality of the laser cutting machine is affected by various factors. In order to obtain the ideal cutting quality, each cutting parameter is limited to a narrow range. At present, we can only rely on repeated experiments to find reasonable cutting parameters under different conditions. Time-consuming and laborious, and unable to respond to disturbance factors in the cutting process. How to quickly find the optimal cutting parameters under different cutting conditions and keep them stable during the cutting process is particularly important. Therefore, it is necessary to study on-line inspection and real-time control of laser cutting quality. The most important indicator of high-quality laser cutting is that there is no cutting defect and the cutting surface roughness value is small. Therefore, the real-time detection target should be able to identify the cutting defect and detect the information reflecting the roughness of the cutting surface. Among them, the roughness information is the most It is important and the most difficult. In the detection of the roughness of the cutting surface, an important research result is to find that the dominant frequency of the pulsation spectrum of the optical radiation signal at the cutting front is equal to the frequency of the cutting fringe of the cutting surface, and the frequency of the cutting fringe is related to the roughness. The radiation signal is related to the roughness of the cut surface. The characteristic of this method is that the detection equipment and signal processing system are relatively simple, and the detection and processing speed is fast, but this method also has shortcomings.   The extracted spectrum and main frequency of the optical radiation signal at the front of the laser cutting machine are only related to the cutting fringes on the upper part of the cutting surface, and do not reflect the cutting fringes on the lower part, and the most valuable information is not mentioned. Because the general cutting surface (except for the cutting of very thin plates) is divided into upper and lower parts, the upper cutting stripes are neat and fine, and the roughness is small; the lower cutting stripes are disordered, and the roughness is large. Maximum roughness. The detection signal only reflects the situation of the best quality area, does not reflect the situation of the lower quality, and does not reflect the information of the worst quality near the lower edge. It is unreasonable and unreliable to use it as a basis for cutting quality evaluation and control. of.
