“…A sorja területének (Ab) mérésekor a forgácsolt geometriáról készített képen a sorja által elfoglalt terület pixeleinek számlálása, majd arányosítása történik (2e. ábra) [11], [16]. Az Ab kvantitatív mérőszám a sorja elhelyezkedésére, valamint karakterisztikájára nem ad egyértelmű információt, továbbá különböző méretű geometriák esetében más kvalitatív jelentőséggel bír az azonos értékű mérőszám.…”

ÖsszefoglalásA szénszállal erősített polimer (CFRP) kompozitok forgácsolása során képződő sorja vizsgálatának és jellemzésének számos módszere és mérőszáma terjedt el, az ezzel kapcsolatos szakirodalmat azonban terminológiai és módszertani inkonzisztencia jellemzi. Ebben a rövid áttekintő cikkben a legelterjedtebb CFRP sorjamérőszámok csoportosítása, elemzése és értékelése történik.

“…Yang et al [2] and Khanna et al [3] considered the ratio of the maximum defect diameter to the nominal diameter of a CFRP hole as the quality evaluation index and studied the influence of cutting parameters on the delamination phenomenon and hole-wall damage. Poor et al [4,5] conducted in-depth research and analysis on the characteristics and formation mechanism of the burr phenomenon of the hole inlet and outlet of CFRP materials. They comparatively discussed the measurement methods and evaluation indicators of the burr phenomenon based on experiment results.…”

Carbon fiber reinforced polymer (CFRP) composites are widely used in various fields because of their high strength, good toughness, and low density. However, owing to their unique forming process, some complex structures such as holes and grooves cannot be formed directly. Therefore, traditional machining procedures are also required. The drilling process is one of the most common machining methods for CFRP material holes, but owing to the complex structure and difficulty in processing CFRP composite material, the quality of the drilling process is often challenging to guarantee. Moreover, the hole-forming defects also have complex forms and lack uniform evaluation indexes. This study summarizes the common orifice defects in the process of CFRP drilling, establishes a comprehensive evaluation method of orifice defects by introducing the relevant theory of the fuzzy complementary judgment matrix, and experimentally verifies the accuracy and reliability of this method. Then, based on the experimental results, a non-linear cutting parameter optimization model is established, which effectively suppresses the orifice defects to ensure the accuracy of the hole size, roundness, and hole wall roughness. The hole-forming quality is subsequently improved. The hole quality evaluation method proposed in this study reduced the dimension of the evaluation index to ensure relevance and effectiveness and improved the convenience of quality inspection and parameter optimization in actual production.

“…Despite the promising early results concerning the material properties of rCFRP, there is no published knowledge available about their machining behaviour; the machinability analysis of rCFRP composites is therefore required. Based on the analogy of gained experiences in virgin CFRP machining, the following main phenomena and challenges are expected in the machining of rCFRP composites: (i) the recycled carbon fibres will have a significant wear effect on the cutting tool [12][13][14]; (ii) in the case of longer (compared to the minimum reinforcement length) fibres, the material properties are orientation-dependent; hence, the machinability of rCFRP will also be orientation-dependent [15][16][17][18][19]; (iii) improper machining technology will induce significant burr formation, delamination, fibre pull-outs and fragmentation [20][21][22][23][24][25][26].…”

Since governments encourage sustainability, industries are making great efforts to reuse or recycle carbon fibre–reinforced polymer (CFRP) composites. Despite the promising early results concerning the material properties of recycled CFRP, there is no published knowledge available about their machinability. In this study, drilling-induced micro and macro-sized geometrical defects were analysed and compared in virgin and recycled CFRP. A total of 180 drilling experiments were carried out using uncoated solid carbide cutting tools. Six different CFRP composites were tested at different feeds. The burr characteristics and microstructure were analysed by optical and scanning electron microscopy. The analysis of variance (ANOVA) results suggest that the formation of drilling-induced burrs in CFRP reinforced by recycled chopped and nonwoven mats is less pronounced than in virgin CFRP. Micro- and macro-sized geometrical defects in both recycled and virgin milled CFRP were negligible. This study found no relevant objection to using recycled CFRP from the point of view of drilling-induced burrs and microstructure damage.
