“…Since the surface roughness is a direct index re ecting the machining quality of the surface [19][20][21][22], in this study the surface roughness of the machined surface is measured through the ZYGO interferometer each time after the tool cutting for the set length introduced in Part 3.1. The sampling length and width are all set as 1.8mm, and the result of each measurement is summarized in Fig.…”

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.

“…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.

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 fibers, 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 influences 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 flank wear. Concretely, the corner wear is rapid, the cutting-edge radius is fluctuating and tends to decrease, while the flank face is wearing constantly. The conclusions of this study can provide foundations for further studies on suppression of the tool wear.
