What are the important effect factors of fiber laser cutting machine
According to the data parameters provided by the fiber laser cutting machine, the important factors that affect its marking effect are speed, power and frequency, so the focus of the test is to compare and analyze these data parameters. The marking font selected in the experiment is Times New Roman. The marking speed is 100mm/s as the base, and five sets of data from 100mm/s to 500mm/s are selected; the power is 10% as the base, and 20% to nine sets of data are selected; The frequency is based on 10KHz, and nine sets of data from 20KHz to 100KHz are selected to test the marking effect of the fiber laser cutting machine.
According to the effect of fiber laser cutting machine, it can be seen that under the condition of the same font, the important factor that affects the marking depth of fiber laser cutting machine is power. Larger, the deeper the marking depth of the marking machine; and under the same power condition, the greater the marking speed, the clearer the marking effect. Since the frequency is only the number of laser vibrations per unit time, it can be seen from the test results that the higher the frequency, the more delicate the visual effect of the marking machine. Therefore, through the above analysis, the test is based on the black painted steel plate, and the comparison is carried out under the condition of different laser parameters. Figure 4 can further prove the expectations of the parameters in the scheme, that is, the smaller the power, the faster the speed, and the shallower the marking depth. Therefore, after a large number of experimental results, it is concluded that under the premise of ensuring the marking efficiency, the output is based on 95% power, and the speed (mm/s) / frequency (KHz) u003d 500 /100 is selected as the better parameter for marking, and the above is completed. A set of text in the picture takes 7s.
At the same time, in order to verify the influence of the font on the marking result, the experiment is carried out under different font conditions when the speed (mm/s) / frequency (KHz)u003d200/30 test. , When using Song Ti as the selected font, the marking effect of the marking machine is in a better state. It can be clearly seen that the marked font is the most beautiful in this state, and the marking traces are also the clearest. At this time, select The font is 6mm in height.
At present, the key element of the fiber laser cutting machine that affects the use of the template is the identification of the word head. The actual template mainly has the effect of erasing the paint surface, which can be roughly divided into wear marks , Scratches, and complete scratches. In the case of unprotected, the text itself can still be clearly seen after the paint is completely scratched off, and the font can also be corrosion-resistant due to the rapid oxidation after marking.
