提出了一种新颖的多刀铣削多个平行的微通道与歧管的挑战，大规模生产所需的成本效益的商业应用。将多把插齿刀叠置在一起，构成一种可同时加工微通道的复合刀具。在不同的加工条件和甲醇水蒸气重整制氢反应特性下，实验研究了这种新工艺的可行性。分析了切削参数和复合刀具对微通道质量和毛刺形成的影响。实验结果表明，较大的切削速度、较小的进给量和切削深度有利于获得较好的微通道质量和较小的切屑。在这些实验中所考虑的所有切削参数中，发现94.2mm min-1的切削速度、23.5mm min-1的进给量和0.5mm的切削深度是最佳值。通过对多刀铣削加工的实验结果与其他替代方法的实验结果进行比较，发现多刀铣削加工比其他替代方法具有更短的加工时间和更高的工件去除率。微通道内甲醇水蒸气重整反应特性也表明多刀铣削工艺可能具有工业应用价值。
A novel multi-cutter milling process for multiple parallel microchannels with manifolds is proposed to address the challenge of mass manufacture as required for cost-effective commercial applications. Several slotting cutters are stacked together to form a composite tool for machining microchannels simultaneously. The feasibility of this new fabrication process is experimentally investigated under different machining conditions and reaction characteristics of methanol steam reforming for hydrogen production. The influences of cutting parameters and the composite tool on the microchannel qualities and burr formation are analyzed. Experimental results indicate that larger cutting speed, smaller feed rate and cutting depth are in favor of obtaining relatively good microchannel qualities and small burrs. Of all the cutting parameters considered in these experiments, 94.2mmin−1cutting speed, 23.5mmmin−1feed rate and 0.5mm cutting depth are found to be the optimum value. According to the comparisons of experimental results of multi-cutter milling process and estimated one of other alternative methods, it is found that multi-cutter milling process shows much shorter machining time and higher work removal rate than that of other alternative methods. Reaction characteristics of methanol steam reforming in microchannels also indicate that multi-cutter milling process is probably suitable for a commercial application.
