Research on the wood processing method of helium-assisted laser process

Abstract In order to promote the development of environmental protection, and usage rate green energy utilization, a progressive, innovative laser process method employing helium assisted is proposed, which optimizes joint cutting under same consumption. This provides new idea for wood industry. The uniqueness this paper establishes mathematical model address diffusion injection heat transfer beam on processed surface. From results, it can be exhibited that oxygen concentration reduces when injected could destroy combustion-supporting conditions decrease combustion zone cutting. Thus, carbonized area surface reduced, effectively enhance processing quality Notably, with speed forms sweeping effect surface, remove parts particles residues as well improve quality. Comparing traditional helium-assisted process, gas-assisted owns higher than detail, features advantages smaller width, lower roughness smoother Eventually, based response evaluation criteria kerf depth, established analyze interaction power, inert gas pressure factors. error between predicted experimental measurement value, optimized parameters acquired. paper, proposed meaningful encouraging, not only obtains better quality, but also guide developing
