摘　　要：木材的切削阻力,进给阻力,锯材的表面粗糙度以及电能的消耗属于木材加工性能的基础研究,其结论对正确的选择机床动力,提高锯材的加工质量和机床的生产率以及改进制材与木材加工工艺也具有实际意义。 我校引种的黑杨派杨和欧美杨,目前全国已有8、9个省进行了种植,有的胸径已达30cm以上,根据规划到本世纪末杨树林可发展到130万公顷,因此发展杨树的加工利用是解决我国木材短缺的一个重要方面。作者在黑龙江省木材工业研究所的支持下对引种中的部分杨树树种进行切削性能实验,并和有关其它树种进行了比较。现将测定过程及结果分述如下。The research project of paper is in an attempt to provide data of various sawing characteristics (e. g cutting force, feeding force and electrical energy consumption etc. ) for effective development and improvement technology and equipment in sawing and woodworking mills. The results from experiments were as follows: 1. The relationship between cutting force and feeding speeds was linear. 2. The relationship between feeding force and feeding speeds was the function relation of the second power. 3. The relationship between power consumption per a unit area of lumber and feeding speeds also was the function relation of second power. 4. The relationship of lumber roughness between fast-growing poplar and other species was similar. 5. Optimum feeding speeds were 0. 3~0. 4 m/s.
