| Summary: | The author uses softwood Pinus koraiensis and hardwood Acer mono which are the common tree species to be the experimental materials in this paper, and the author mainly discussed several factors affecting the morphology of wood surface burr. In addition to macro factors which are mechanical parameters, feeding speed, rotating speed of cutting tool, tool shape, cutting tool shape Angle, the sharpness of cutting tool and wood moisture content, this paper is to study the effects of microstructure of wood internal burrs morphology on machining surface. The burr morphology of two species trees under different conditions were observed by scanning electron microscope, and then the author summarize the effects of wood microstructure on the burr processing surface, the microstructure of wood includes trees density and the early wood and late wood at the same species, wood surface texture, angle of processing surface etc. These are to establish the mathematical model of wood burr, and to prepare subsequent for laser ablation, and they can provide research foundation for the laser sanding on the surface of wood products.
