Abstract

• Delamination and surface quality in drilling of fiber reinforced polymer composites. • Effects of cutting parameters, cutting tool material and geometry on the delamination. • Effects of adhesion and abrasive wear mechanisms on the delamination and surface quality. Fiber reinforced polymer composite materials are important for aerospace industry due to their engineering properties. the delamination that occurs during cutting these materials with different cutting methods is adversely affecting engineering properties. This situation is prevalent especially in drilling operations. it has been found that stacking methods have been used in recent years and delamination has been significantly reduced. Therefore, in this study, it was aimed to transfer the findings obtained by researching the innovative studies made in the literature to the readers. Purpose: The aim of this study is to identify the findings obtained from recent studies in the literature. Theory and Methods: In this study, it is aimed to reveal the results obtained from the innovative studies carried out within the scope of the study. Results:I n the industrial applications, especially in aircraft industry, it is necessary to use the optimum cutting speed values in the stacked structures. However, in the case of stacked structures, it is necessary to use the optimum cutting speed values for each material. Ti or Al, FRP's/Ti, FRP's/Ti, FRP's/Ti and FRP's/Al/ FRP's stacked structures are used in the body and wing connections. Due to the adherence of the chips (BUE) to the machined surface and the cutting edge of the cutting tool due to adhesion, micro-level particles broken off from metal and FRP's materials due to the mechanical loads cause abrasive wear on the cutting tool. It has been determined that MQL and spray spray cooling method which can be used with PCBN or PCD tools as well as stepped or small angled point drills to minimize delamination, increase hole quality of metal and FRP's material to cause delamination in FRP's material. Conclusion: It has been determined in the literature that low cutting speeds should be used in combination with high cutting speeds in order to reduce delamination. However, in addition to the cutting parameters, cutting tool geometry, coating method, and material type also have significant impact on cutting performance. It is considered that the abrasive water jet cutting method may be advantageous for metal-stacked ETPK structures in that the drilling of the front hole can reduce the occurrence of delamination particularly in the ETPK layers stacked with metals, thereby reducing the thermal effects that may occur during cutting. In addition, the relationship between the different fiber angles and the surface damage occurring at the cutting surface is of great importance in terms of the effectiveness of the results obtained by performing different statistical modeling studies for estimating the cutting temperatures in different regions as well as delamination, burr formation, cutting force and surface roughness in st...
