“…Three main numerical models have been proposed to investigate the cutting process of CFRP, that is, the micro-scale, [9][10][11] macroscale, [12][13][14] and mesoscale finite element model. [15][16][17] And the numerical models have been developed from the twodimensional (2D) to the three-dimensional (3D) at the past decades. These models showed that the principal cutting force predicted fairly acceptable in their model, which agreed with the experimental results, although the thrust force was still not compliant.…”

A three-dimensional (3D) microscopic finite element (FE) cutting model was developed with the thermo-mechanical coupling for carbon fiber reinforced polymer (CFRP) composites in this article. The model predictions of cutting force, machined surface, and cutting temperature at various fiber orientations were obtained and compared with the experimental data. It was shown that the 3D microscopic cutting model can predict the cutting force, cutting temperature, and subsurface damage precisely. The behavior of cutting force has presented an obviously cyclical variation characteristics at the fiber orientations of 0 , 45 , and 90 , and different chip morphologies were obtained correspondingly. The temperature fields of machined surface were studied at the four different fiber orientations, in which the maximum residual temperature on the machined surface occurs at 90 . The heat-induced resin coating and resin ridges on the machined surface were obviously observed at the fiber orientations of 45 and 135 . The trend curve of cutting temperature is more similar with that of thrust force by comparing with cutting force, which meaning, unlike the isotropic metal materials, the thrust force has the direct effect on the heat generation. In addition, the comparison of depth of thermal and mechanical subsurface damage was also performed, it was showed that the depths of thermal subsurface damage are close to that of mechanical subsurface damage in the range of 0 -45 , and the thermal subsurface damage decrease while the mechanical subsurface damage increases with the increase of the fiber orientation range from 90 to 180 .

“…Furthermore, crack tip plasticity and creep behaviour of polymers during cutting conditions are completely different in metal materials. In recent years, orthogonal micro-cutting of polymers has drawn increasing attention [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Regarding the numerical method for orthogonal micro-cutting of polymers, Venu Gopala Rao et al [ 19 ] developed an FE model to machine CFRP and GFRP composites.…”

In the present work, an explicit finite element (FE) model was developed for predicting cutting forces and chip morphologies of polymers from the true stress–strain curve. A dual fracture process was used to simulate the cutting chip formation, incorporating both the shear damage failure criterion and the yield failure criterion, and considering the strain rate effect based on the Johnson–Cook formulation. The frictional behaviour between the cutting tool and specimen was defined by Coulomb’s law. Further, the estimated cutting forces and chip thicknesses at different nominal cutting depths were utilized to determine the fracture toughness of the polymer, using an existing mechanics method. It was found that the fracture toughness, cutting forces, and chip morphologies predicted by the FE model were consistent with the experimental results, which proved that the present FE model could effectively reflect the cutting process. In addition, a parametrical analysis was performed to investigate the effects of cutting depth, rake angle, and friction coefficient on the cutting force and chip formation, which found that, among these parameters, the friction coefficient had the greatest effect on cutting force.

“…It was found the ber orientation is the key factor that affects cutting process. With the developing of numerical techniques, simulation models in micro scale [4]-[6], macro scale [7] [8] and multi-scale [9] [10] have been built to study the so called cutting mechanism. Similar results to Wang's work were found that ber orientation controls machined surface roughness, subsurface damage and cutting forces.…”

The current cutting strategies for carbon fiber reinforced polymer (CFRP) inherit essentially from metal cutting. The frequently occurred damages such as burrs, cracks and delamination suggest that the existed strategies may not be the best choice for CFRP cutting. This study proposed a sliding cutting strategy especially for CFRP. The novelty is adding an extra lateral velocity on cutting edge to act sliding motion between fiber-matrix and the cutting edge. Then the stress in the materials in front of cutting tip will become more concentrated, which will help to break fibers in desired positions. Thus, the machining quality can be improved. The sliding cutting process was analyzed and experiments were conducted to examine the proposed strategy. Two types of cutting tools that offered sliding and orthogonal cutting were designed. Four factors, namely machined surface roughness, subsurface damages, forces and tool wear, were obtained to evaluate the cutting quality. Results show that sliding cutting has more advantages than orthogonal cutting in CFRP machining.
