DOI: 10.1007/s00170-020-06163-3 http://doi.org/10.1007/s00170-020-06163-3 Machining of carbon fibre reinforced polymer (CFRP) composites is extremely difficult, mainly due to their inhomogeneous and anisotropic properties. Predicting of cutting force during machining of CFRP is also difficult because the machinability properties of the composite are significantly orientation-dependent (fibre and machining directions). The main objective of the present study is to analyse the influence of fibre orientation on cutting force in milling of unidirectional CFRP. Up and down milling experiences were conducted based on a full factorial design. Experimental data were processed by fast Fourier transformation, regression analysis, and graphical adequate analysis. Multiple-order polynomial models were developed in order to minimise cutting force. Experimental results show that fibre orientation angle significantly influences the cutting force; furthermore, it does not have a significant effect on the passive force component, while the radial force component is more sensitive to the fibre orientation at up milling, than at down milling. An optimal condition is recommended for zig-zag milling of unidirectional CFRPs.

(in Chinese) DOI: 10.3901/JME.2016.17.058 http://doi.org/10.3901/JME.2016.17.058 On account of heterogeneous and anisotropic nature of the carbon fiber reinforced plastic (CFRP) in macroscopy and a special state of fiber-resin mixture in microscopy, delamination, cracks, etc. are easily generated in the manufacturing process, which greatly reduces the bearing capacity and machining accuracy of final parts. The key to improve machining quality lies in exploring the mechanism of CFRP subsurface damages for the purpose of damage reduction. In this paper, the orthogonal cutting simulation model that can realize the unidirectional CFRP continuously dynamic cutting process at any fiber orientation is developed based on macroscopic anisotropy constitutive behaviors, Hashin initial failure criterion and the damage evolution. Also analysis of subsurface damages in the unidirectional CFRP continuously dynamic cutting process of is made to acquire influences of fiber orientation, cutting parameters and tool geometries on the damage depth. Detailed results are listed as follows: Subsurface damages are mainly impacted by fiber orientation, and with the increase of the orientation, the cutting force rises, and so is the damage depth. The mechanism of subsurface damages is matrix fractures led by excessive cutting force and the resulting damage propagation; the damage depth first increases and then decreases with the augment of the tool rake angle for unidirectional CFRP with 135° fiber orientation.
