“…It is evident in Figure 4 that the flank-wear along the cutting edges increases with increasing cutting speed (revolutions per minute). Similar results regarding the effect of cutting speed on wear are found in the literature [28,43,50]. However, this increment in the wear progression is slight at higher cutting speed of 12,000 rpm as compared to 9000 rpm.…”

Abstract:The drilling of carbon fiber reinforced polymer (CFRP) plate is very critical in its structural applications in aeronautical, aerospace, and automobile industries. For ensuring the good quality of drilled holes in terms of least drilling damage and prolonged tool life, suitable selection of drill geometry and material, and drilling parameters-such as cutting speed and feed rate-are imperative in the drilling of CFRP plate. This study aims to evaluate the cutting performance of conventional two-flute twist drills made of cemented tungsten carbide YG6X (WC-6 wt % Co) for the dry drilling of the multidirectional T700 CFRP plate. The effects of varying cutting speed and tool wear pattern on the drilling performance are analyzed. The drilling performance is assessed in terms of hole quality by the qualitative and quantitative analysis of drilling-induced delamination and hole diameter. Furthermore, the correlation between the tool wear progression and the drilled hole quality is established. Through this assessment, a suitable set of drilling parameters, i.e., cutting speed of 9000 rpm and feed rate of 400 mm/min, is proposed for producing the best quality holes for multidirectional T700 CFRP plate.

A three-dimensional micromechanical finite element cutting model with the thermo-mechanical coupling was developed for carbon fiber reinforced polymer composites in the paper. The finite element modeling considers the three phases of a composite, in which the interphase between the fiber and matrix can realize heat transfer and allow debonding to represent the failure of composites. The model predictions of the machining responses, such as cutting temperature and subsurface damage, at different fiber orientations were compared with various experimental data for model validation. It is indicated that the three phase micromechanical model is capable of precisely predicting cutting temperature and the damage induced by the cutting tool. It was found that cutting temperature and subsurface damage strongly depend on the fiber orientation. Subsurface damage is easily occurs in a fiber orientation range of 90°–135°, while the largest depth of the thermal damage occurs at 90°. In addition, the effect of machining parameters on the cutting temperature was investigated based on the cutting model. It was showed that the cutting speed should be reasonably selected to control the cutting temperature. The temperature decrease with increase the rake angle, while increase with increase depth of cut and radius of cutting edge.

“…Indeed, the chip formation of synthetic fiber composites depends on the matrix nature. For thermoset composites, the removed chip is often discontinuous or powdery [26][27][28][29][30][31][32][33][34][35]. This is inherently related to the mechanical behavior of the thermoset composite during the cutting solicitations.…”

This is an author-deposited version published in: https://sam.ensam.eu Handle ID A B S T R A C TThis paper aims to study the machinability of natural fiber reinforced thermoplastic composites by investigating the mechanics of chip formation and the multiscale cut surface's quality induced by the orthogonal cutting process. Unidirectional flax fibers reinforced polypropylene (UDF/PP) composite has been tested by orthogonal cutting experiments. Mechanical tensile and shear tests have been conducted on UDF/PP specimens to relate the mechanical behavior to the cutting behavior. Results show that UDF/PP composites produce a continuous chip at all the considered cutting conditions. This is inherently related to the specific mechanical behavior of flax fibers inside the thermoplastic matrix under cutting solicitations. The cutting behavior induces a consequent surface damages in the form of debonding zones and uncut fiber extremities. Results demonstrate that the cutting depth has the most significant influence on the machinability after sorting the pertinent scales of the cut surface using the multiscale surface analysis approach.
