摘要

采用博世GCM 12 GLD Professional斜锯机对软硬木材进行横切时，锯片齿数对运动学和动力学参数的影响进行了评价。使用三维XYZ测力仪Kistler 9257B测量的力和随后基于数学模型的计算应用于Ernst-Merchant图，并分析和比较了切割云杉和橡木板时的力。采用直径为300 mm、不同wz形齿数(z = 26、36、48、60)的四把几何形状和结构相似的刀片进行木材切割。然后通过统计分析对给定切削条件下的最佳锯片进行评估。与许多研究木材横向和纵向切削阻力的研究不同，本实验和力分析是在恒定进给力的情况下进行的。

Impact of Circular Saw Blade Design on Forces During Cross-Cutting of Wood

This paper evaluates the impact of the number of saw blade teeth on kinematic and dynamic parameters during cross-cutting of soft and hard woods with mitre saw BOSCH GCM 12 GLD Professional. The forces measured using a three-dimensional XYZ dynamometer Kistler 9257B and subsequent calculation based on a mathematical model were applied in the Ernst-Merchant diagram and the forces acting in the cutting of spruce and oak planks were analysed and compared. The wood cutting was performed by four geometrically and structurally similar blades with a 300 mm diameter and with different count of WZ-shaped teeth (z = 26, 36, 48, 60). The optimum saw blade for the given cutting conditions was subsequently assessed by statistical analysis. Unlike many studies researching the cutting resistances in transversal and longitudinal wood cutting, this experiment and force analysis was performed in dependence on the constant feed force.
