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.

“…Different drill bits have been studied to reduce the thrust force during drilling processes [2,3], as the large thrust force usually leads to delamination when the drilling tool approaches the exit plane. Through optimizing the cutting parameters (such as feed rate and spindle speed) [4][5][6] and using back-up plate [7], the delamination of composites can be suppressed to a certain extent. Tsao and Hocheng [8] presented a drilling-induced delamination detective method by using computerized tomography which was a feasible and an effective tool compared with ultrasonic scan.…”

“…An empirical model of the maximum thrust force and torque was described in their subsequent study [20]. Lazar et al [21] found that the maximum load per ply was strongly affected by the axial feed rate and the tool geometry, according to the experiments of drilling FRPs with three different tools (including the tapered drillreamer). Xu et al [22] used a chemical vapor deposition (CVD) coated twist drill bit and a CVD coated tapered drillreamer for drilling high-strength CFRP laminates (T800S/ 250F CFRP laminates), and the drilling forces, burr defect, hole wall surface morphology, and delamination damages were comparatively analyzed.…”

The thrust forces and delamination in drilling carbon-reinforced plastics (CFRPs) using a tapered drillreamer have been studied by experimental and theoretical analyses. A theoretical drilling model of the tapered drillreamer has been established to study the developing process of the push-out delamination, and a comprehensive analysis for the thrust force and the delamination has been developed in the present study. The results obtained in this study show that the maximum thrust force measured in the drilling stage (F z1max ) is drastically affected by the machining parameters (spindle speed and feed rate). However, the maximum thrust force measured in the reaming stage (F z2max ) is not sensitive to the machining parameters, and the multiple N between F z1max and F z2max increases with the increase of feed rate but decreases with the increased spindle speed. Moreover, according to the theoretical drilling model, the thrust force thresholds at the onset and the propagation of delamination in the reaming stage are 29.57 and 51.34 N, respectively. In order to improve the hole quality, the length of the cutting edges of the tapered drill-reamer should be about 9.6 mm, and the improved drilling method of placing two rigid plates on both sides of CFRPs workpiece is preferred.
