Through comparing the cutting width, heat affected zone (HAZ), and surface burning conditions under different gas-assistance conditions, the influence of the added gases on the gasification and combustion of cherry wood was analyzed. Using identical processing parameters, the cherry wood was laser-cut with and without the added gases. Unsupported combustion nitrogen (N 2) and flame-retardant helium (He) were used to facilitate laser-cutting of cherry wood, and the effects of process parameters, gas flow, and gas reactivity on the surface quality of thin wood were studied. Qingwei Liu, a,b Chunmei Yang, a,b,* Bo Xue, a,b Qian Miao, a,b and Jiuqing Liu a,* Processing Technology and Experimental Analysis of Gas-assisted Laser Cut Micro Thin Wood This study combined gas processing and laser technology, and it provided technical references for reducing post treatment improving the surface quality of laser-processed wood. The surface of the kerf was observed with a scanning electron microscope, and addition of He gas remarkably improved the burning that occurred when cutting kerf. This indicated that He gas had good oxygen isolation and flame-retardant effects. Under the same conditions, when He gas was added, the burning areas on both sides of the kerf were remarkably reduced and the consistency of kerf was good. When N2 gas was used, the cutting width was less than that of laser direct cutting, but the surface of the burning area did not remarkably improve.
