Study on Influencing Depth of Surface in Drilling Process of Carbon Fiber Reinforced Plastic
-
摘要: 采用正交试验的方法，研究了钻孔过程中主轴转速、刀具进给速度、刀具磨损对碳纤维复合材料（Carbon fiber reinforced plastic，CFRP）钻削表面影响层厚度的影响规律。结合不同的纤维切削角时复材切削机理，研究了不同纤维切削角对制孔表面影响层厚度的影响规律。结果表明：刀具磨损对表面影响层厚度影响最大，主轴转速次之，进给速度的影响最小；影响层厚度随刀具磨损的增大而增大，随主轴转速和进给速度的增大而减小；纤维切削角在90° < θ < 180°时，会产生严重的加工影响层，而在0 ≤ θ ≤ 90°时，不会产生明显的影响层。Abstract: The orthogonal test is designed to study the influence of the spindle speed, feed speed and tool wear on the depth of surface damages of carbon riber reinforced plastic(CFRP). According to the different cutting mechanisms corresponding to different fiber orientations, the effects of the different fiber orientations on the depth of surface damages of composite materials was analyzed. The results show that the tool wear has the greatest influence on the depth of surface damages, the spindle speed is the greater, and the feed speed is the least. In addition, the depth of surface damages increases with the increasing of tool wear, while it decreases with the increasing of spindle speed and feed speed. It will have obvious depth of surface damages only at the orientations of fiber between 90° and 180°.
