“…The milling of the Nomex honeycomb structure behaves as conventional composite materials when dealing with the problem of damage induced during the chip formation process (Sun 1996). Several researchers have experimentally studied the influence of cutting conditions on cutting forces and the quality of the machined surface for this type of material, (Karpat et al 2012;Yaozhi 2019;Xiang et al 2019;Fang 2013). For machining honeycomb structures by milling, it is necessary to optimize the processing conditions (feed speed and speed of rotation).…”

The machining of Nomex honeycomb structures represents a technical and scientific barrier for aeronautical applications. The difficulties encountered during the machining of this type of material are linked to the low density of Nomex paper, and to the low thickness of the walls forming the honeycomb cells of this type of structure. In this work, a finite element calculation code "ABAQUS`-EXPLICIT" was used to optimize and analyze the machining by milling of Nomex honeycomb structures. The main objective of this work is to study the influence of the machining conditions on the cutting forces, and the morphology of the chips.

“…Zhang et al [16] summarized the characteristics of the surface microscopic of Nomex honeycomb by the location of the feature and analyzed the influence of feed rate and ultrasonic vibration amplitude to the damage form. In addition, Xiang et al [17] developed a new ultrasonic longitudinal-torsional vibration-assisted cutting method, in which the machined surface with better quality can be obtained when compared to ultrasonic longitudinal vibration-assisted cutting. Although studies on the ultrasonic cutting technology of Nomex honeycomb core have been performed in various ways, there are only two kinds of special tools for ultrasonic cutting, include straight blade and disc-cutter [2].…”

The vertical surface is a common and typical characteristic structure among Nomex honeycomb core components. However, the conventional high-speed milling and ultrasonic cutting struggle to meet the high-quality machining requirements of a vertical surface. In this study, an ultrasonic trepanning method is proposed and a special ultrasonic trepanning tool is developed, aiming to improve the machining quality of the vertical surface. The trepanning quality of the vertical surface is further studied from the aspects of dimensional error and trepanning incision quality. Based on the kinematic characteristics of ultrasonic trepanning, a theoretical model of dimensional error in trepanning is established. Meanwhile, the influence of ultrasonic vibration on the trepanning process is analyzed, and the result shows that ultrasonic vibration significantly improves the equivalent elastic constant of the honeycomb core material. The theoretical model is proposed to predict the trepanning dimensional error, which is verified by experiment. The effectiveness of the ultrasonic vibration on the incision quality is verified by several experiments, and the quantitative analysis results demonstrate that ultrasonic vibration significantly improves the trepanning quality of the vertical surface.

“…To understand the machinability of these structures, experimental tests were carried out, taking into account the complex geometry of honeycombs and the cutting tool. [8][9][10] As the machined surface integrity is strongly related to the manufacturing process, it becomes necessary to optimize the machining parameters to improve the surface quality. Several authors have examined the cutting conditions on the surface quality as well as the cutting forces during milling of Nomex honeycomb structures.…”

In machining, tool/workpiece interface parameters are complicated to estimate by experimental means alone. Numerical methods can then give critical solutions to predict and analyze the parameters influencing the machining. The friction between the tool and the cutter has a direct influence on the milling parameters. Therefore, it is necessary to understand the friction mechanism between the tool and the workpiece to estimate the milling parameters of Nomex honeycomb structures correctly. This work aims to present a 3D Finite Element numerical model allowing the prediction of the cutting forces correctly, the morphology of the chips, and the surface quality generated during the milling of this type of structure. These studies were obtained using the commercial software ABAQUS/Explicit. It has been demonstrated that the coupling between the isotropic elastoplastic approach and the Coulomb friction law can easily simulate the milling of Nomex honeycomb structures and gives excellent results in comparison with those obtained experimentally.
