In the process of wood surface processing, it is easy to cause safety accident. Therefore, it is very necessary to find a new and clean processing method instead. In this paper, the laser automatic processing method is used instead of manual work, exploring the ablation of milled wood surfaces with nanosecond pulse laser. Four commonly used kinds of wood were selected, and milled separately in three different directions. The generation mechanism of micro burrs was analyzed under different working conditions. Then, a laser ablation experimental platform was established, and used to ablate the milling-induced burrs on the four kinds of wood. The ablated surfaces were observed under a scanning electron microscope (SEM). Based on the observations, the interaction between laser and surface burrs was investigated, and laser ablation deburring was modelled on ABAQUS. On this basis, the authors discussed how laser ablation deburring is affected by multiple laser parameters. The results show that cross-grain milling leads to more burrs on wood surface than parallel-to-grain milling and against-grain milling; for nanosecond laser ablation of wood surface burrs, the ablation efficiency and ablated surface quality could be optimized, when the output power falls between 300 mJ and 400 mJ; when the other parameters of the laser remain unchanged, there exists an optimal power density that helps to remove the surface burrs, without greatly affecting the nearby areas. The research results shed important new light on the deburring of wood products with the aid of pulse laser. Finally, it is proved that the mode of laser machining instead of traditional manual operation is feasible.

在木材表面处理过程中，容易引起安全事故。因此，非常有必要找到一种新的干净的处理方法。在本文中，使用激光自动处理方法代替手工操作，探索了纳秒脉冲激光对铣削木材表面的烧蚀。选择了四种常用的木材，并分别在三个不同的方向上进行研磨。分析了不同工况下微毛刺的产生机理。然后，建立了激光烧蚀实验平台，用于烧蚀四种木材上的铣削毛刺。在扫描电子显微镜（SEM）下观察烧蚀的表面。根据观察结果，研究了激光与表面毛刺之间的相互作用，在ABAQUS上模拟了激光烧蚀去毛刺。在此基础上，作者讨论了多个激光参数如何影响激光烧蚀去毛刺。结果表明，与平行磨法和逆磨法相比，交叉磨法在木材表面产生更多的毛刺。对于纳秒级激光烧蚀木材表面毛刺，当输出功率在300 mJ至400 mJ之间时，可以优化烧蚀效率和烧蚀表面质量。当激光器的其他参数保持不变时，存在最佳功率密度，可帮助消除表面毛刺，而不会极大地影响附近区域。该研究结果为借助脉冲激光对木材产品去毛刺提供了重要的新思路。最后，
