金刚石线锯切割碳纤维复合材料实验研究

为研究金刚石线锯切割碳纤维复合材料的锯切工艺，在总结国内外大量文献资料的基础上，利用自行研制的金刚石线锯切割加工机床对金刚石线锯切割碳纤维材料进行了实验研究。实验结果表明：适当降低线锯进给速度和提高线锯线速度时碳纤维复合材料的切缝轨迹更加理想；金刚石线锯在线速度较低和线锯张紧力较高条件下的稳定性较好；切向锯切力随线锯线速度的增加而减小，更有利于保证工件切割质量；法向锯切力随线锯进给速度的增加而增大；线锯上金刚石颗粒分布不均、工件厚度和位置及线锯运动方向的改变，使得碳纤维材料线缝轨迹不是理想的直线。

Study of Diamond Wire Saw Cutting of Carbon Fiber Composite Material

To study the sawing technology of diamond wire saw cutting carbon fiber composite, the experiments of cutting the carbon fiber composite materials on a diamond wire saw cutting machine tool were performed. The results show that the joint-cutting path of carbon fiber composite material is more perfect under the conditions of lower feed speed and higher wire saw linear speed; the stability of diamond wire saw is higher under the conditions of lower linear speed and higher tension of diamond wire saw; the tangential sawing force decreases with the increase in wire saw linear speed；the normal sawing force increases with the increase in wire saw feed speed; the uneven distribution of diamond abrasive grains , the different thicknesses and clamping positions of the work pieces and the wire saw cutting direction result in the joint-cutting path of carbon fiber composite material being not an ideal straight line.
