“…This is could be due to the increase in the friction between the cutting tool and the machined surface [27]. S. Gara et al [51] measured the cutting temperature during machining of a multidirectional CFRP laminate. The experiments were conducted on a computer numerical control (CNC) machine with the Our observation from Figure 4 is that under identical cutting conditions, cutting forces increase as the spindle speed increases from 10,000 to 20,000 rpm.…”

This article presents the influence of machining conditions on typical process performance indicators, namely cutting force, specific cutting energy, cutting temperature, tool wear, and fine dust emission during dry milling of CFRPs. The main goal is to determine the machining process window for obtaining quality parts with acceptable tool performance and limited dust emission. For achieving this, the cutting temperature was examined using analytical and empirical models, and systematic cutting experiments were conducted to assess the reliability of the theoretical predictions. A full factorial design was used for the experimental design. The experiments were conducted on a CNC milling machine with cutting speeds of 10,000, 15,000, and 20,000 rpm and feed rates of 2, 4, and 6 µm/tooth. Based on the results, it was ascertained that spindle speed significantly affects the cutting temperature and fine particle emission while cutting force, specific cutting energy, and tool wear are influenced by the feed rate. The optimal conditions for cutting force and tool wear were observed at a cutting speed of 10,000 rpm. The cutting temperature did not exceed the glass transition temperature for the cutting speeds tested and feed rates used. The fine particles emitted ranged from 0.5 to 10 µm aerodynamic diameters with a maximum concentration of 2776.6 particles for those of 0.5 µm diameters. Finally, results of the experimental optimization are presented, and the model is validated. The results obtained may be used to better understand specific phenomena associated with the milling of CFRPs and provide the means to select effective milling parameters to improve the technology and economics of the process.

“…In [ 28 ], an experimental study of slotting of multidirectional CFRP laminate using three micro grain carbide burr tools with different geometries and an infrared thermograph camera was carried out to investigate tool-workpiece contact point temperature, chip temperature, machined surface damage, subsurface defects, and tool degradation. Empirical models were established to show the dependence of cutting temperature on tool geometry and cutting conditions.…”

Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and machining conditions is therefore required, taking into account that the phenomena responsible for material removal in cutting of fibre reinforced plastic composite materials are fundamentally different from those of conventional metals and their alloys. To date, composite materials are increasingly used in several manufacturing sectors, such as the aerospace and automotive industry, and several research efforts have been spent to improve their machining processes. In the present review, the key issues that are concerning the machining of fibre reinforced plastic composite materials are discussed with reference to the main recent research works in the field, while considering both conventional and unconventional machining processes and reporting the more recent research achievements. For the different machining processes, the main results characterizing the recent research works and the trends for process developments are presented.

“…During polymer machining, various complex issues are encountered by manufacturers like circularity error, roughness, burr, fiber pull, matrix debonding, etc. 10,11 The machined samples’ surface roughness plays a critical role in affecting the quality and productivity indices. It acts as a primary concern during polymers’ machining because various aesthetic requirements are dependent upon the surface quality.…”

“…It is also strongly correlated with other cutting performances such as surface finishing, tool wear, and interface temperature. 11,12 Besides this, the carbon fiber/epoxy composites are anisotropic and non-homogeneous; in turn, the machining concept completely differs from other polymers and metals. The reinforcing fiber and cutting tool contact area develop a deformation zone for the cutting of material.…”

The machining behavior of polymers is substantially different from metal and their alloys due to non-homogeneity and anisotropy. This article describes a hybrid optimization method during machining (milling) of epoxy nanocomposites reinforced by graphene oxide/carbon fiber (G/CF). The milling experimentation was staged according to the L9 orthogonal array of the Taguchi theory. The control of process constraints, namely, cutting speed (Vc), feed (F), depth of cut (D), and G weight % (G) have been appraised to acquired the desired machining response such as material removal rate (MRR), cutting force ( F c), and surface roughness ( R a). Grey-coupled principal component analysis (grey-PCA) effectively tackled the response priority weight during aggregation of conflicting responses. The optimal condition secured by the grey-PCA module are found as Vc = 25.12 m/min, F = 240 mm/min, D = 0.5 mm, and G = 1 %. The supplement of graphene enhances the machining characteristics of the nanocomposites, which in turn, minimizes the damages that occur during the milling process. Scanning electron microscopy (SEM) analysis was conducted for microstructure investigation of the machined component. The findings of confirmatory experiments show good agreement with the actual ones. The preferred solution values of grey-PCA are observed as 1.027, which confirms the proposed technique’s higher practicability.
