“…Therefore, efficient chip evacuation prevents the temperature from rising and thus reduces the occurrence of both matrix burn in composite laminates and regions affected by heat in metals. Very few investigations on the ability of the OD process to achieve high-quality drilled holes have been performed for CFRP [196][197][198][199], CFRP/Ti [43,194,195,[200][201][202][203] and CFRP/Al stacks [102,136]. Orbital drilling, also named helical milling, produces holes using an end mill that rotates around its own axis while being driven by a helical advance, as depicted in Figure 18.…”

In recent years, the use of hybrid composite stacks, particularly CFRP/Al assemblies, and fiber metal laminates (FMLs) has progressively become a convincing alternative to fiber-reinforced polymers (FRPs) and conventional metal alloys to meet the requirements of structural weight reduction in the modern aerospace industry. These new structural materials, which combine greater mechanical properties with low specific mass, are commonly assembled by riveted and bolted joints. The drilling operation, which represents the essential hole-making process used in the aerospace industry, proves particularly challenging when it comes to achieving damage-free holes with tight tolerances for CFRP/Al stacks in one-shot operations under dry conditions due to the dissimilar mechanical and thermal behavior of each constituent. Rapid and severe tool wear, heat damage, oversized drilled holes and the formation of metal burrs are among the major issues induced by the drilling of multi-material stacks. This paper provides an in-depth review of recent advancements concerning the selection of optimized strategies for high-performance drilling of multi-material stacks by focusing on the significant conclusions of experimental investigations of the effects of drilling parameters and cutting tool characteristics on the drilling performance of aerospace assemblies with CFRP/Al stacks and FML materials. The feasibility of alternative drilling processes for improving the hole quality of hybrid composite stacks is also discussed.
