CFRP/钛合金叠层构件制孔孔径分布规律研究

为了研究CFRP/钛合金叠层构件一体化制孔加工后的孔径几何精度变化规律及主要影响因素,在CFRP/钛合金制孔基础上,利用三坐标测量机对孔径几何精度进行检测,并分别对单个孔及系列孔的孔径几何精度进行分析,得到孔径几何精度的变化规律及主要影响因素。结果表明:叠层材料制孔加工过程中材料加工性能的巨大差异,使加工至材料界面时产生的切削振动较大,是影响CFRP与钛合金孔径几何精度的主要因素,且对CFRP孔径影响较大,对钛合金孔径影响较小。

Aperture Geometry Precision of CFRP/Titanium Alloy Laminated Structure

To study the variation law of aperture geometric precision and the main influencing factors of the integration process of the CFRP/titanium alloy laminated structure,this paper uses three coordinate measuring machine of Hexagon aperture to detect the geometric accuracy and the geometric accuracy of the single aperture hole diameter and hole geometry precision are analyzed based on the CFRP/titanium alloy hole machining.Some factors change law of aperture of geometric accuracy and main effect.The results show that the stacks layer material of holes machining process in material processing performance of the huge disparities,the processing to the material interface produced larger vibration cutting,the main factors influenced CFRP and titanium alloy aperture geometry precision,and the diameter of CFRP influence larger and less influence of aperture on the titanium alloy.
