- Abstract
A study of a hole-making experiment for AFRP was carried out using two cutting methods, drilling, and milling, respectively, to analyze the surface morphology, cutting force, hole wall morphology, and tool wear, as well as to conduct the test under MQL conditions, and to compare the situation with that in dry cutting. It was found that the drilling of holes had more burrs on the inlet surface, surface roughness and poor roundness, and fewer burrs on the outlet surface and better quality, and the opposite was true for milling, with fewer burrs on the inlet surface, good surface quality and roundness, and more burrs on the outlet surface and poor roundness. After the use of MQL, the cutting surface edge bulge expansion, free resin block, and resin smearing phenomenon significantly reduced or even disappeared, but the surface burr inhibition effect is limited. At the same time, the observation of the hole wall found that the MQL conditions of the shear effect are apparent, the fiber fracture surface is neat, and we can see the orthogonal weaving intersection of the upper and lower layers of fibers. By establishing the response surface model of cutting force, the drilling cutting force achieves the minimum value in the interval, and the milling cutting force achieves the maximum value in the interval. The study shows that the cutting force of AFRP hole-making shows a laminar solid nature, and its laminated structure has a strong reflection, especially the axial force signal; the cutting surface morphology has a great relationship with the cutting mode and the system stiffness/strength; the increase of the feed speed makes the single cutting fiber volume increase, and the extrusion of the cutting surface is enhanced, which inhibits the surface burr to a certain degree. After the weighting analysis, it was found that the interaction between cutting speed and feed rate was reduced, and the individual effect of each influencing factor was enhanced, which was conducive to exerting the cutting efficiency of the tool itself. In addition, the study also found that the contact point between the tool and workpiece is also one of the influencing factors of the cutting surface morphology and makes the surface burr problem more complicated.
