“…Particularly in the milling process of the blind slots, because the bers and resin are cut in semi-closed space, the heat generated is more di cult to give out and thereby the resin is more likely to soften, leading to the more severe tool wear and the worse surface quality. Since the qualities of the bottom surface of these blind slots are crucial to the assembly performance of the CFRP components, it is di cult to ensure the reliable service of the components without the deeply reveal on the wear laws and mechanisms of the tool [6][7][8][9].…”

End cutting edges of tool determine machining quality of the bottom surface of the slot in end-milling of CFRP. However, due to anisotropy and heterogeneous of CFRP, and also semi-closed characteristic of blind slots, the end cutting edges are more vulnerable to wear than the peripheral edges under the strong abrasive bers, leading to the poor machining quality of the bottom surface of the slots, and thereby decreases the assembly performance of the components. This paper aims to reveal the wear laws and mechanisms of the end cutting edge which serves under the poor machining conditions in end-milling of CFRP. In order to obtain major wear forms of the end cutting edge, the tool's structure and the removal characteristics in end-milling of CFRP are analysed. For acquiring the wear laws accurately, slot-milling experiments are conducted, in which the quantitative characterization of each wear form is proposed. According to the wear laws obtained from the experiments, combining with the associated relationships of each wear form, the wear mechanisms of end cutting edge are revealed, and also, the in uences of the tool wear on the surface's machining quality are got. The results show that there are three wear forms in all including the corner wear, the cutting-edge wear and the ank wear. Concretely, the corner wear is rapid, the cutting-edge radius is uctuating and tends to decrease, while the ank face is wearing constantly. The conclusions of this study can provide foundations for further studies on suppression of the tool wear.

“…In their previous studies, the authors developed a milling tool for CFRP using polycrystalline diamond (PCD) with excellent tool wear property [5,6]. The surface roughness achieved using this tool was better than 1.0 μmRa-this is well within the surface roughness tolerance for aircraft, i.e., 3.2 μmRa [7].…”

Carbon-fiber-reinforced plastic (CFRP) is used in various industries such as aerospace and automobile industries because of its high mechanical characteristics. However, this material is difficult to cut. Tool wear and delamination frequently occur during the drilling or cutting of CFRP. In previous studies, we developed a CFRP cutting tool using polycrystalline diamond (PCD). The PCD tool exhibited excellent cutting performance at cutting speeds as low as <120 m/min. In this study, the authors investigated the effect of cutting speed on the face milling of CFRP by using the developed PCD tool.

“…However, Nguyen D N [ 21 ] found that when the machining distance of CFRPs with a PCD tool reached 1.68 m, the maximum tool wear was only 11 μm. In addition, more literature [ 22 , 23 , 24 ] shows that machining CFRPs with a PCD tool not only results in low tool wear, but also is more conducive to obtaining better surface quality.…”

Carbon-fiber-reinforced polymers (CFRPs) have been widely used in many industrial fields, such as automobile, aerospace and so on, because of their excellent mechanical properties. However, due to their anisotropy and inhomogeneity, machining CFRPs is a great challenge. In this paper, the slot milling of a plain-woven CFRP with PCD tools is carried out, and the effects of cutting parameters and tool rake angle on cutting force and surface roughness are studied. The results show that the 4° rake angle PCD tool has smaller cutting force than the 0° rake angle PCD tool, but the effect of rake angle on surface roughness is not significant. The concept of equivalent cutting area is introduced to study the variation law of cutting force and surface roughness. It is found that the cutting force and surface roughness increase with the increase in equivalent cutting area, and decrease with the decrease in equivalent cutting area. The removal mechanism of surface materials under different equivalent cutting areas is different, which leads to the difference in surface roughness. Finally, the causes of delamination on the top layer after milling are explained.
