摘要
针对浮雕家具表面的毛刺无法实现机械化砂光的问题,提出了采用纳秒脉冲激光烧蚀的解决方法。在本研究设计的激光加工试验平台上,以山杨木材为试材,研究不同输入电流、切削进给速度对木材激光烧蚀效果的影响,观察烧蚀后木材微观组织的变化,探讨纳秒脉冲激光试验参数对烧蚀深度的影响。试验结果表明,随着输入电流的增加,木材表面的炭化加剧,输入的电流为5m A时,获得最优的表面质量,同时在不同的进给速度下,烧蚀出现深度拐点。
Mechanized sanding of the burrs existed in the surface an approach of laser ablation with nanosecond pulse was proposed of anaglyph furniture cannot be conducted, and in this study. On the platform of laser processing, by using Populus davidiana Dode as tested material, the effect of input current and cutting feed speed on laser ablation wood was analyzed, and the change of wood microstructure after laser ablation was observed. The results showed that the wood carbonization was intensified with the increase of input current, and the best quality of wood surface was produced when the input current was 5 mA. In the meantime, the ablation depth inflection point occurred at different feed velocity.
