木材表面粗糙度的分析

该文采用探针法测定水曲柳、毛白杨和杉木不同加工表面的粗糙度，分析了影响木材表面粗糙度的因素. 并采用心理分析方法讨论了木材表面的粗糙感，以及触觉心理量与视觉心理量的关系. 为获得不同树种、切削加工方式、切面对木材工件表面粗糙度的影响，该实验分别选择了锯切、铣削、刨切和磨削加工的木材工件表面进行表面的粗糙度和粗糙感触觉心理量、视觉心理量的测量. 研究结果表明，树种、切削方式、切面和木材的表面组织构造会影响木材的表面粗糙度；表面粗糙度值因为加工方法不同而不同，随着加工精度的提高而降低. 水曲柳、毛白杨和杉木表面粗糙感的触觉心理量与视觉心理量呈正相关，针叶材表面粗糙感的触觉心理量与视觉心理量的相关性比阔叶材的大.  

Roughness and roughness sense of wood surface from different machining processes

Surface roughness of Fraxinus mandshurica Rupr., Populus tomentosa Carr. and Cunninghamia lanceolata(Lamb.)Hook. wood from different cutting processes was measured by a stylus method and analyzed with various factors. Then the surface roughness sense was analyzed by a psychometric method and the relation between the psychological values of touching and vision was discussed. The sawed, milled, peeled and sanded surfaces of wood pieces were used to measure the surface roughness and the psychological values of touching and vision, in order to obtain the effects of the wood species, method of machining, radial or tangential section and wood surface structure on the surface roughness of wood. Results show that species, method of machining, radial or tangential section and wood surface structure affect the surface roughness of wood. The roughness of wood surfaces decreases with the increase in processing precision. The correlation between the psychological values of touching and vision for softwoods is a little higher than that of hardwoods.
