Characteristics of carbon–carbon composite turning

High performance cutting of advanced aerospace alloys and composite materials

“…While carbide tools possess the highest transverse rupture strength and fracture toughness, diamond tools have the highest hardness and thermal conductivity. This explains the use of the former for roughing operations and the latter for finish machining [67]. Although ceramic tools have high thermal stability, in machining of FRPs they tend to fail by chipping; recently, some progress was made in improving the performance of these tools, by using SiC-whisker reinforcement [105].…”

“…The random orientation of the diamond crystals prevents the propagation of cracks, and thus improves the tool toughness. The typical operating cutting speed for this tool material is 200-2000 m/min [67,169,223]. Carbide end mills with brazed PCD tips (780-900 m/min) that feature opposite cutting edge directions were shown to reduce delamination and improving tool performance.…”

Turning of glass–fiber reinforced plastics materials with chamfered main cutting edge carbide tools

“…Also, the tool-wear-rates of the machining of glass-fiber reinforced plastics were studied. Ferreira et al [7] showed that turning experiments were observed with the performance of different tool materials like ceramics, cemented carbide, cubic boron nitride (CBN), and diamond. During the tests the tool wear, the machining forces, and engine motor current were measured.…”

Development of novel tool for cutting of carbon-fiber-reinforced plastics (Positive use of abrasive wear at tool edge for reduction in cutting force)

“…In the machining of CFRP composites, the abrasive wear on the flank face characterizes tool wear processes. Therefore, high-hardness materials, such as polycrystalline diamond (PCD) and chemical vapor deposition (CVD) diamond, are commonly used in CFRP cutting tools (Sakuma, et al, 1985;Ferreira, et al, 1999;Ferreira, et al, 2001;Lantrip, 2008;Chatelain and Zaghbani, 2012).…”
