| 摘 要： | 采用锯齿磨损变钝程度不同的硬质合金切削刀具对三种木材(杉木、樟子松、水曲柳)和两种人造板(中密度纤维板、刨花板)进行闭式切削实验,研究锯齿磨损变钝程度对木质材料切削力的影响规律。实验结果表明,随着刀具磨损变钝程度的增加,主切削力和法向力都呈增大趋势,且法向力的增幅更明显。负间隙C对中纤板主切削力、法向力以及刨花板法向力的影响曲线类似,均为先缓慢上升,再急剧增加,然后又趋于平缓;刨花板主切削力随负间隙C的增加而不断增加。

| Abstract: | Three kinds of solid wood,China fir,Mongolian pine,Manchurian ash,and two kinds of wood-based panel,MDF and PB,were used to do close-cut experiment;and the influence of different tungsten carbide-tipped saw tooth wearing and blunting levels on woody material cutting force were studied.Experiment results showed that both principal and perpendicular cutting forces increased with wearing level increasing,and the latter increased more obviously.The curves of cut surface compression to both MDF principal and per... |
