Abstract: In this paper, the influence of the parameters of CO2 laser cutting system on the rhombus microchannel is studied. In the experiment, we changed the laser processing speed, laser processing power, and laser processing number of CO2 laser cutting system, and the depth and width of microchannel are studied by changing these three parameters. It is found that the depth and width of microchannel increase with the increase of laser processing number and laser processing power. For example, when the speed is 6mm/s and the number of laser processing is three times, the width of microchannel increases from 0.51mm to 0.64mm and the depth increases from 0.75mm to 1.60mm with the increase of power. However, the depth and width of the microchannel decrease with the increase of laser processing speed. For example, when the power is 8W and the number of laser processing is three times, the width of the microchannel decreases from 0.51mm to 0.39mm, and the depth of the microchannel decreases from 0.75mm to 0.34mm.
