碳纤维增强复合材料具有轻质高强等优点,近年来在航空航天领域多有应用。钛合金具有强度高、密度低、耐热性好等优良性能。在航空制造领域,往往将CFRP和Ti-6V-4V合金叠加在一起使用,而二者需用螺栓连接,因此就需要钻孔加工,而这种材料钻孔加工的研究报告极少。为此采用超硬钻头对CFRP和Ti-6V-4V合金的叠层材料进行了钻孔加工,研究切削条件、刀具涂膜种类与刀具磨损的关 Carbon fiber reinforced composites have the advantages of light weight and high strength. In recent years, they have many applications in the field of aerospace. Titanium alloy with high strength, low density, good heat resistance and other excellent performance. In the field of aviation manufacturing, CFRP and Ti-6V-4V alloy are often used in superposition together, and the two need to be bolted, so the drilling process is required, and there are few reports on the drilling processing of this material. To this end, the superhard drill bit was used to drill the laminated materials of CFRP and Ti-6V-4V alloy to study the cutting conditions, the type of tool coating and the tool wear
