“…The increase in the cutting force and torque with repeated drilling is due to the increase in the worn area of the tool. Similar results were obtained for the cutting force (Park et al 2011;Wang et al 2014b;Çelik et al 2015) and torque (Park et al 2011;Wang et al 2014b) during drilling of carbon fiber reinforced polymer, but the magnitude of cutting force and torque was different.…”

“…Bone is different than metal or composite as it is a complex material (Yu et al 2005) in the form of layers containing a soft tissue, hard tissue, bone marrow and protein fibers. The phenomena of wear on the tool is characterized by friction between the drill bit and workpiece (Park et al 2011;Çelik et al 2015). As the number of drilled holes increase, the cutting edge of a drill bit becomes dull and its sharpness diminishes which may be the cause of increase in the friction between the drill tool and bone in CD.…”

“…They also studied the influence of tool material (HSS, HSS-Co and carbide) and cutting conditions on thrust forces, tool wear and holes quality. Park et al [7] investigated drilling of CFRP/Ti stacks in terms of tool wear mechanism when using carbide and polycrystalline diamond tools. They highlighted cutting edge abrasion due to the CFRP and adhesion of the Ti on tool cutting edges and flank faces.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. A scanning electron microscope (SEM) and a numerical microscope, provided with a scanning device, were periodically used to analyse tool wear mechanisms and to measure wear progression of the tool cutting edges. For both coated and uncoated drills, abrasion was the dominant tool wear mechanism, affecting the entire cutting edges. Higher wear was observed on uncoated tools which caused a significant increase in thrust force during drilling both Al and CFRP materials. The influence of these phenomena on the quality of the holes and on the generated roughness was also discussed.

“…The sharp geometry of the cutting edge (hence a higher residual stress concentration) can lower the coating bonding strength [33,34], making them more prone to flaking and subsequent degradation. In addition, it is generally accepted that tool wear under machining of CFRP is mainly concentrated on the cutting edge [17,32,35]. When machining the Ti/CFRP stacks, the cutting tools are subjected to a higher residual temperature (as a result of machining the top Ti alloy), this would accelerate the cutting edge wear during the subsequent machining process.…”

AbstractCarbon fiber reinforced plastic (CFRP) and titanium alloy stacks are typical difficult-to-machine materials and often results in rapid tool wear, leading to a low drilling efficiency in aircraft assembling. Helical milling process has demonstrated its superior performance in making holes in these materials, but selecting a proper cutting tool is still a great challenge and little research has been carried out to investigate the effect of different coatings on tools performance. Therefore, in this paper, milling tools with and without coatings (diamond coating, TiAlN+AlCrN multilayer coating and TiAlN coating) were employed in helical milling of Ti/CFRP stacks. The cutting performance and the degradation mechanisms of these milling tools were investigated in details. It is found that, uncoated tools demonstrate the best cutting performance with lowest cutting force, highest hole quality and slightest tool wear. Degradation of nitride coated tools is due to the combined effects of increased roundness of cutting edge and the strong dependence of cutting performance on the tool sharpness. Diamond coated tools showed the greatest degradation, which has been attributed to the low materials ductility at tool cutting edge, weak adhesive strength between the coating and substrate, and the poor thermal resistance of the diamond coating.
