TL;DR: A comprehensive literature review on machining of carbon fiber reinforced plastics/polymers is given with a focus on five main issues including conventional and unconventional hybrid processes for CFRP machining, cutting theories and thermal/mechanical response studies, numerical simulations, tool performance and tooling techniques, and economic impacts as mentioned in this paper.
Abstract: Carbon fiber reinforced plastics/polymers (CFRPs) offer excellent mechanical properties that lead to enhanced functional performance and, in turn, wide applications in numerous industrial fields. Post machining of CFRPs 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 difficult process due to the highly nonlinear, inhomogeneous, and abrasive nature of CFRPs. In this paper, a comprehensive literature review on machining of CFRPs is given with a focus on five main issues including conventional and unconventional hybrid processes for CFRP machining, cutting theories and thermal/mechanical response studies, numerical simulations, tool performance and tooling techniques, and economic impacts of CFRP machining. Given the similarities in the experimental and theoretical studies related to the machining of glass fiber reinforced polymers (GFRPs) and other FRPs parallel insights are drawn to CFRP machining to offer additional understanding of on-going and promising attempts in CFRP machining.

TL;DR: In this paper, a face turning test was performed on GFRP cylindrical pipes which contained uni-direction fibers (right-hand-winding or left-handwinding) and others.
Abstract: Since the glass-fiber-reinforced plastics (GFRP) is non-homogeneous, the cutting behavior of this material differs from that of a homogeneous material such as steel. It is, therefore, difficult to analogize the tool wear mechanism in GFRP cutting from the data obtained in the cutting of homogeneous materials. In this study, a face turning test was performed on GFRP cylindrical pipes which contained uni-direction fibers (right-hand-winding or left-hand-winding) and others. The cutting resistance and surface roughness were measured to analyze the machinability and the tool wear mechanism in GFRP cutting. Thus, the relation between the fiber orientation and tool wear becomes clear ; e.g., there is a significant difference in the wear rate between right-hand-wound material and left-hand-wound one.

TL;DR: In this article, the temperature at the cutting edge of a tool in machining glass-fiber-reinforced-plastics was measured by a special thermocouple method, in which two insulated wires were embedded in the workpiece, and the hot junction of the thermocycle was established when these wires were cut together with the work piece.
Abstract: The temperature at the cutting edge of a tool in machining glass-fiber-reinforced-plastics was measured by a special thermocouple method, in which two insulated wires were embedded in the workpiece, and the hot junction of the thermocouple was established when these wires were cut together with the workpiece. The temperature distribution along the cutting edge, and the relation between the physical property (thermal conductivity) of tool materials or cutting speed (spindle speed) and the temperature at the cutting edge were analyzed to estimate the relation between the cutting temperature and the flank wear of cutting tools.
