文章应用单纯型法，对CO2激光制作孔径为100μm的盲孔参数进行优化。以盲孔的真圆度和上下孔径比为优化目标函数，经优化过程获得最佳工艺参数，并对最佳工艺参数进行实验验证。根据水平效应关系对影响CO2激光钻孔的因素进行效应分析，从而确定因素之间的主次关系。结果表明，最佳工艺参数为：脉宽13.8μs，脉冲能量14.8 mJ，脉冲次数2，光圈（Mask）2.2 mm，所得盲孔孔型最好，真圆度达到99.32%，上下孔径比为82.36%。对真圆度影响的主次关系是：脉冲能量>脉冲宽度>脉冲次数>Mask；对上下孔径比影响的主次关系是：Mask>脉冲能量>脉冲宽度>脉冲次数。该方法得到的最佳工艺参数能够为实际生产提供参考。

Simplex optimization was studied for parameter optimization of CO2 laser during drilling the blind hole of 100μm in diameter. The optimum parameters were obtained and tested while composite index of roundness and ratio of upper and lower aperture was applied as optimization target. The effects of factors, such as laser energy, diameter of beam, pulse width and pulse shot, on roundness as well as ratio of upper and lower aperture were analyzed. The experimental data showed that the optimum parameters are pulse width 13.8 μs, laser energy 14.8 mJ, pulse shot 2, and mask 2.2 mm, resulting in the roundness 99.32%, and ratio of upper and lower aperture 82.36%. The importance of factors from primary to secondary on roundness is:pulse energy>pulse width>pulse shot>Mask, and on ratio of upper and lower aperture is:Mask pulse>energy>pulse width>pulse shot. In generally, the optimized parameters are important references for industrial production.
