“…Based on the identification of harmful sets of cutting parameters, the authors proposed the variable feeding method to reduce the delamination damage of fibrous composites and found that the use of the new drilling method could reduce the push-out delamination factor by 37% for the CFRP material. Loja et al [10] carried out an assessment of thermally influenced and delamination-induced regions during the drilling of fibrous composites. It was found that the tool geometries and the thickness of the workpiece were the key factors affecting significantly the drillinginduced damage of the composite laminates.…”

“…angle as denoted in Fig.6. Different types of fiber removal processes associated with the laminate orientations and drill geometrical features determine the final cut surfaces and the subsequent hole defects.Figures 7,8,9,10,11,and 12 present the surface morphologies of CFRP holes produced by three…”

“…At the same time, it was observed that the pushout delamination is initiated in a shorter amount of time at higher cutting speed because of heat generated, which makes the matrix softer and less stiff (Krishnaraj et al, 2012). It is also observed that due to the low feed rate and high speed, a temperature rise occurs, which in turn enhances the delamination in the composite (Geng et al, 2017;Loja et al, 2018). In contrast, Gaitonde observed that delamination was minimized by enhancing the cutting speed of the tool in traditional machining of carbon fiber composites (Gaitonde et al, 2008).…”

“…Typically, carbon fiber-reinforced plastic (CFRP) is employed as the metals substitutions in lots of weight-critical components in aerospace, owing to the good properties, such as high specific strength, high specific stiffness and high modulus [1][2][3][4][5]. In reality, subsequent machining operations, such as milling, drilling, are necessary to be required for assembling [6].…”
