“…The main types of mechanical wear in CFRP machining include chipping (also called fracture) and abrasion. In accordance to different locations where wear occurs, wear phenomena observed include nose wear as discussed by Sakuma et al [113] and Caprino et al [11], flatik wear by Santhanakrishnan et al [114] and Inoue et al [115], Cutting direction Fig. 25 Chipping of the WC drill in high speed drilling of CFRP [116] edge chipping by Rawat and Attia [116] and Shyha et al [117], and edge rounding by Uhlmann et al [118], and Schulze et al [119] (also called edge dullness wear or edge recession in Wang et al [120]).…”

“…were commonly considered to significantly affect tool wear. Flank wear was observed to become more intensive with the increase in cutting speed in GFRP machining [124], while Sakuma et al [113] found that the cutting speed has a much smaller effect on the wear rate during CFRP turning as compared to GFRP turning. On the other hand, Lin and Chen [12] experimentally investigated the effect of cutting speed on tool wear during CFRP drilling processes and found that tool wear increased significantly with the increase in cutting speed.…”

“…31 [133]. HSS was observed not to be suitable for cutting owing to high tool wear rates and poor surface finish [30], while carbides and diamond tools were found to perform well in CFRP machining [113] as well as in GFRP machining [134]. Carbide tools offer the flexibility of various tool geometries, while diamond tools offer high hardness and wear resistance [135].…”

Carbon fiber reinforced plastieslpolymers (CERPs) offer excellent mechanical properties that lead to enhanced functionat performance and, in turn, wide apptications in numerous industrial fietds. Post machining of CERPs is an essential procedure that assures that the manufactured components meet their dimensional tolerances, surface quality and other functional requirements, which is currently considered an extremely difficutt process due to the highly nonlinear, inhomogeneous, and abrasive nature of CERPs. In this paper, a comprehensive literature review on machining of CERPs is given with a focus on five main issues including conventionat and unconventional hybrid processes for CERP machining, cutting theories and thermatlmechanical response studies, numerical simulations, tool performance and tooting techniques, and economic impacts of CERP machining. Given the similarities in the experimental and theoretical studies retated to the machining of gtass fiber reinforced polymers (GERPs) and other ERPsparaltet insights are drawn to CERP machining to offer additionat understanding of on-going and promising attempts in CERP machining.

“…In summary, filament fracture will impact the tool edge, which blunts the cutting edge and causes tool wear. Several studies indicated that the dominant tool wear mode was cutting edge rounding (CER) in machining CFRPs [6], [9], [13], [14], [16][17][18][19][20][21][22][23][24]. Faraz et al [6] proposed a latent wear characteristic CER as a measure of sharpness/bluntness of uncoated cemented carbide tools when drilling CFRP composite laminates.…”

“…Moreover, different wear studies [26,27] were performed in order to analyse the tool wear behaviour dependencies on tool materials and tool coatings. Based on an experimental study with different tool materials, Sakuma et al [27] concluded that the wear rate decreases with increasing hardness of the tool material. In consequence of their high wear resistance, the predominant amount of researchers recommend cutting tools made of cemented carbide or polycrystalline diamond (PCD) [28,29].…”

Machining abrasive carbon fibre reinforced polymers (CFRP) is characterised by extensive mechanical wear. In consequence, the cutting edge micro-geometry and thus the tool/material contact situation are continuously changing, which affects process forces and machining quality. As a conclusion, a fundamental understanding of the tool wear behaviour and its influencing factors is crucial in order to improve performance and lifetime of cutting tools. This paper focuses on a fundamental tool wear analysis of uncoated tungsten carbide cutting inserts with different combinations of fibre cutting angles and tool geometries. For this purpose, orthogonal machining experiments with unidirectional CFRP material are conducted, where the wear progression of the micro-geometry is investigated by means of five wear parameters lα, lγ, γ*, α*, and bc. For detecting the actual contact zone of the cutting edge and to measure the elastic spring back of the material, the flank face is marked via short pulsed laser processing. Furthermore, the process forces and the wear rate are measured. It is shown that the material loss due to wear clearly varies along the tool’s contact region and is highly dependent on the clearance angle and the fibre cutting angle Φ, while the influence of the tested rake angles is mostly negligible. Especially in machining Φ=30° and Φ=60°, a strong elastic spring back is identified, which is more intense for smaller clearance angles. For all tested configurations, the material’s elastic spring back increases in intensity as wear progresses which, in combination with the decreasing clearance angle, is the main reason for high thrust forces.
