摘要:
 研究基于对黄柏木的横、径向切面的铣削加工试验,得到不同的加工表面,然后借助扫描电镜对加工后的表面木纤维的破坏形式进行了观察,随后分析了不同加工方向下,黄柏木表面纤维的断裂形式和形成机制,讨论了铣削方向对木材表面质量的影响因素。结果表明,横、径向加工方向的不同会影响加工效率及能耗;顺、逆纹加工路径的不同会影响纤维的断裂形态和形成机理;铣削过程中纤维拉断和撕裂情况的不同则会影响加工后的木材表面质量。研究结果为不同木材、不同加工方式和方法等因素对木材破坏机制影响的进一步试验分析奠定了基础。
Abstract:
 Timbers of Phellodendron amurense were milled along transverse and radial sections.Surfaces of the milled timber were observed by scanning electron microscope to examine the damages after being milled.The failure forms and mechanisms of the surface cellulose were analyzed.Factors affecting the wood surface quality by different milling directions were discussed.From the experimental results and mechanism analysis,it was concluded that milling directions affected the processing efficiency and energy consumption,the difference of the processing path determined the fracture morphology and formation mechanism,and in the process of milling,fiber breaking and tearing influenced the surface quality.The results of the experiments would lay the foundation for the further study on the effects of different woods,different processing methods on the failure mechanism of woods.
