摘要

在锯切加工中，锯切功率对能耗具有重要影响。采用硬质合金圆锯片对栎木（,Quercus, spp.）进行锯切试验，探究锯切参数（锯齿前角、锯片转速及进给速度）对栎木锯切功率的影响，通过3因素3水平设计27组全因子试验，对锯切参数进行方差分析，并建立锯切功率的回归模型。结果表明；随着锯齿前角增大、主轴转速增大，栎木锯切功率减小；随着进给速度增大，栎木锯切功率增大。各锯切参数对锯切功率的影响程度排序为：进给速度＞锯片转速＞锯齿前角。根据方差分析结果建立线性模型的决定系数为0.9065，25° 锯齿前角在不同锯切参数下的锯切功率预测值与实测值的相对误差绝对值最大仅8.22%，表明该模型适用于栎木锯切功率的预测。

Abstract

High energy consumption is a common problem in wood sawing; while the cutting power significantly affects the energy consumption. In this study, oak wood (,Quercus, spp.) was cut with carbide circular saws to investigate the effect of sawing parameters (rake angle, rotation speed, and feed speed) on the cutting power. The power was measured in 27 sets of tests through a 3-factor, 3-level design. The sawing parameters were analyzed by variance analysis. A regression equation for cutting power was established. The results show that the cutting power during sawing oak wood decreases as the rake angle of the saw teeth increases; the cutting power decreases as the rotation speeds increases; and the cutting power increases as the feed speed increases. The effect of each sawing parameter on the cutting power is in descending order: feed speed ,>, rotation speed ,>, rake angle. The coefficient of determination of the linear model based on the analysis of variance is 0.9065. The regression equation predicts that when the cutting power is calculated at 25° of the rake angle under different sawing parameters, the error rate is less than 8.22% compared to the measured value, indicating that the model is suitable for predicting the cutting power of oak wood.
