【摘要】：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。
[Abstract]:In order to study the sawing technology of carbon fiber composites cut by diamond wire saw, based on the summary of a large number of literature at home and abroad, the cutting carbon fiber material of diamond wire saw was studied by using the diamond wire saw cutting machine developed by ourselves. The experimental results show that the cutting track of carbon fiber composites is more ideal when the feed speed of wire saw is properly reduced and the wire speed of wire saw is increased, the stability of carbon fiber composite material is better when the on-line speed of diamond wire saw is lower and the tension force of wire saw is higher, the tangential cutting force decreases with the increase of wire saw speed, which is more beneficial to ensure the cutting quality of workpiece, and the normal cutting force increases with the increase of wire saw feed speed. The uneven distribution of diamond particles on the wire saw, the change of the thickness and position of the workpiece and the movement direction of the wire saw make the line seam trajectory of carbon fiber material not an ideal straight line.
