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.

CO2激光快速制造金刚石微混合器的研究

本文研究了CO ₂激光切割系统参数对菱形微通道的影响。在实验中，我们改变了CO ₂激光切割系统的激光加工速度、激光加工功率和激光加工数量，并通过改变这三个参数来研究微通道的深度和宽度。发现微通道的深度和宽度随着激光加工次数和激光加工功率的增加而增加。例如，当速度为 6mm/s，激光加工次数为3倍，微通道宽度从0.51增加毫米至 0.64mm，深度从 0.75 开始增加毫米至 1.60mm 随着功率的增加。然而，微通道的深度和宽度随着激光加工速度的增加而减小。例如，当幂为 8W和激光加工次数为3倍，微通道宽度从0.51减小毫米至 0.39mm, 微通道深度从 0.75 减小毫米至 0.34毫米。
