“…As shown in Figure 1b, the two sides of scratched groove indeed exhibited two different fibre cutting angles under one fibre orientation angle, and thus 0 • , 30 , 120 • and 150 • of the fibre cutting angles θ were involved. To reveal the material removal behaviour and damage characteristics during the CFRP scratching process, a super high magnification lens zoom 3D microscope (VHX-600E, Keyence Co., Ltd., Osaka, Japan) and a scanning electron microscope (SEM) (QUANTA 450, FEI Co., Ltd., Hillsboro, TX, USA) were employed to observe the scratched grooves [42].…”

Carbon fibre-reinforced plastic (CFRP) composites, prized for their exceptional properties, often encounter surface quality issues during slotting due to their inherent heterogeneity. This paper tackles CFRP slotting challenges by employing multi-tooth mills in experiments with various fibre orientations and tool feed rates. In-plane scratching tests are performed under linearly varying loads; then, slotting experiments are conducted at different parameters. The scratching test results indicate that the fibre orientation and cutting angles have significant influences on forces and fracture process. The slotting experiments demonstrate that cutting forces and surface roughness Sa of the bottom slotting surface are notably affected by the fibre orientation, with disparities between up-milling and down-milling sides. Reorganising Sa data by local fibre cutting angle θ highlights consistent Sa variations between up-milling and down-milling sides for 0° ≤ θ ≤ 90°, with lower Sa on the up-milling side. However, for 90° < θ ≤ 150°, Sa variations diverge, with lower Sa on the down-milling side. Unexpectedly, Sa on the down-milling side decreases with increasing θ in this range. Additionally, the tool feed rate exerts a more pronounced influence on Sa on the up-milling side.
