Abstract

Current article was devoted to FEM modelling of damages machined surface of unidirectional CFRP (carbon fiber reinforced plastic). Modelling was performed on micromechanical level. Based on the proposed spatial arrangements of fibers relative to the cutting edge and the direction of main motion to convert 3D-process of drilling CFRP in 2D- equivalent orthogonal cutting. During numerical simulation, it was found that the angle of fibers orientation affects the average value of cutting force, amplitude of oscillation and depth of damage at the machined surface. The smallest impact on machined surface damage was detected at samples with angle of fiber orientation θ = 45°, which was proved in experimental study.
