“…Takeyama and Iijima [11] proposed a minimum energy machining model for predicting cutting forces as a function of fiber direction and cutting tool rake angle. Bhatnagar et al [12] proposed a machining model similar to the model of Takeyama and Iijima [11] in which they observed that fracture and shearing take place during chip formation process depending on the fiber direction. Wang et al [13] conducted orthogonal cutting experiments on unidirectional laminates and observed greater thrust forces than cutting forces due to elastic recovery of the fibers.…”

a b s t r a c tCarbon fiber reinforced polymer (CFRP) usage in the aerospace industry has been steadily increasing due to its superior material properties such as high strength, low weight, high resistance to corrosion, and a low thermal expansion coefficient. In addition, CFRP parts are produced near-net-shape, a process that eliminates rough machining operations. However, machining operations such as drilling, side milling, and slotting are still necessary to give the CFRP parts their final shape. A majority of the studies on machining of CFRP laminates are on drilling. The number of studies on milling of CFRPs is quite limited. In this study, a mechanistic cutting force model for milling CFRPs is proposed based on experimentally collected cutting force data during slot milling of unidirectional CFRP laminates using two different polycrystalline diamond cutters. Cutting force coefficients in radial and tangential directions are calculated as a function of fiber cutting angle. The relationship is represented with simple sine functions. The mechanistic model is shown to be capable of predicting cutting forces during milling of multidirectional CFRP laminates. The experimental milling force measurements and predicted milling forces agree well with each other. Surface milling experiments were also conducted to investigate the relationship between milling forces and surface quality. Some suggestions on surface milling of CFRP laminates are given based on these observations.

“…Source: Astakhov and Osman (1996), Mamalis et al (2005) and Taylor (1907) In the case of fibre reinforced plastic composites, their heterogeneous structure and anisotropic properties affect the material removal operations (Bhatnagar et al, 1995;Dandekar and Shin, 2012;Konig et al, 1985). The brittle nature of polymer matrices, especially of thermosets, leads the material to be fractured (Dandekar and Shin, 2012), instead of suffering a plastic deformation process as in the machining of metals and alloys (De et al, 1994;Taylor, 1907;Xiong et al, 2013).…”

“…The machining of fibre reinforced plastics became a field of study since the utilisation of these materials increased, due to their superior specific mechanical properties (Bhatnagar et al, 1995;Dandekar and Shin, 2012;Konig et al, 1985;Liu et al, 2012). Machining operations like trimming, turning, grinding, milling and drilling are not only intended to shape the part, however also to enable effective assembly processes for finished parts.…”

This work investigates the applicability of Taylor's model on the drilling of CFRP using uncoated WC-Co tools, by assessing the influence of cutting speed (V c ) on tool wear. Two different resins, possessing low and high glass transition temperatures (T g ), and two different reinforcements, high strength and high modulus woven fabrics, were combined into three different systems. Flank wear rate gradient exhibited to be more reinforcement dependent, while the actual flank wear rate showed to be sensible also to the type of resin. In terms of tool life, all CFRP systems adjusted into a power-type tool life vs. cutting speed curve through the full range of cutting speeds (1,000 RPM to 18,000 RPM). Therefore, Taylor's model can be applied to estimate the tool life in the drilling of CFRP using uncoated WC-Co tools with good accuracy. 96 J.L.
