摘要: PCD木工圆锯片的锯齿结构参数对切削过程中刀具磨损起决定性作用,它的尺寸变化直接影响加工工件的表面质量及精度。采用有限元的方法对不同结构参数PCD木工刀具圆锯片切割时的受力及变形情况进行了模拟计算分析,发现:其加工中的最大压应力集中在锯齿背部区域、最大拉应力集中在锯齿根部附近区域,最大变形在切削速度方向,其最佳锯齿结构参数为前角γ=15°、后角α=15°。Abstract: The cutter parameters of PCD wood cutting circular saw blades play a decisive role in the cutting process.They directly affect the machining surface quality and tool life.Simulation analysis of the cutting force and deformation of different cutter parameters of PCD wood circular saw blades is carried out using finite element method.The results show that the stress concentrate in the back area and root area of the cuter,the maximum deformation take place in the cutting velocity direction and the best cuter parameters of the PCD circular saw blades are rake angle γ 15° and rear angle α 15°.
