| Layered structures consisting of CFRP composites and aluminum alloys are most commonly used in the aerospace, marine, construction and automotive industries. One of the most important aspects associated with their use is the difficulty of machining them due to the anisotropic nature of the structures. These structures are often jointed to each other by mechanical joints that require mounting holes. The purpose of this study was to determine the effect of drill bit diameter, cutting speed and the way the specimen is clamped during machining (drilling strategy) on the quality of holes drilled in a II-layer structure consisting of CFRP composite and aluminum alloy. The quality of the holes was expressed by the hole accuracy index D. A visual evaluation of the holes after the drilling process was also carried out. The most accurate holes (the lowest value of s, a cutting speed of v c = 90 m/min and an Al/CFRP drilling strategy. The lowest dimensional accuracy of the hole was also obtained at the exit of v c = 30 m/min and an Al/CFRP drilling strategy. The values of the D index and visual evaluation of the holes also made it possible to note that for this type of material it is more favorable, considering the dimensional accuracy of the holes, to use a CFRP/Al drilling strategy. |
