“…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.…”

“…However, significant cutting resistance, which is detrimental to the quality of machined parts, is generated due to the CFRP's inhomogeneous and anisotropic characteristics, low thermal conductivity, and high tensile and fatigue strength [9]. Besides, the intrinsic laminates [42,43]. However, the medium strength CFRP (T700) has been almost neglected in relation with the drilling operation.…”

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.

“…For instance, when drilling FRP-phase, the cutting tool suffers severe edge rounding wear and intense flank wear due to the abrasive nature of the reinforcing fibers [104,105]. Abrasion, fracture and chipping due to thermal and mechanical loads are confirmed to be the major wear modes by most research work [104,[106][107][108]. As for Ti-phase drilling, the serious Ti chip adhesion coupled with the high localized temperature concentrated at the tool-chip interface easily results in severe adhesion wear, edge chipping and tool fracture.…”

“…The excellent performance of special drill bits globally has a close relation with the mentioned geometrical variables, which results in minimal hole damage and minor tool wear in drilling action. Xu et al [65,106] and An et al [116,117] compared the tool performances of one standard twist drill and one special drill (namely "dagger drill") in drilling of high-strength CFRP phase. It was found that the dagger drill promoted better surface finish, i.e., less burr defect and smaller delamination damage than the twist drill due to its smaller point angle and helix angle.…”

Hybrid composite stack, especially FRP/Ti assembly, is considered as an innovative structural configuration for manufacturing the key load-bearing components favoring energy saving in the aerospace industry. Several applications require mechanical drilling for finishing hybrid composite structures. The drilling operation of hybrid FRP/Ti composite, however, represents the most challenging task in modern manufacturing sectors due to the disparate natures of each constituent involved and the complexity to control tool-material interfaces during one single cutting shot. Special issues may arise from the severe subsurface damage, excessive interface consumption, rapid tool wear, etc. In this paper, a rigorous review concerning the state-of-the-art results and advances on drilling solutions of hybrid FRP/Ti composite was presented by referring to the wide comparisons among literature analyzes. The multiple aspects of cutting responses and physical phenomena generated when drilling these materials were precisely addressed. A special focus was made on the material removal modes and tool wear mechanisms dominating the bi-material interface consumption (BIC) with respect of investigating strategies used. The key conclusions from the literature review were drawn to point out the potential solutions and limitations to be necessarily overcome for reaching both (i) enhanced control of drilling operation, and (ii) better finish quality of FRP/Ti parts.

“…The model reveals that delamination and other workpiece defects can be controlled by selection of suitable step drill geometry. Xu et al [9] have examined the performance of two types of poly-crystalline diamond (PCD) drills (PCD standard twist drill and PCD specialgeometric dagger drill) in drilling of high-strength CFRP (T800S/250F) composites. The results confirm that the PCD dagger drill seems to provide a better tool-work configuration than the PCD twist drill for high-strength T800S/250F drilling in terms of better hole quality, lower tool wear and longer tool life.…”
