“…Such findings revealed the fundamental flank wear features of drill edges during the drilling of CFRPs and highlighted the vital role of the instantaneous cutting speed on the wear extents. Barik and Pal (2022) addressed the tool wear progression of different tools when drilling woven CFRP composites. The results indicated that the flank wear was increased with an increase in the number of holes irrespective of the tool type.…”

Carbon fiber reinforced polymer (CFRP) laminates are featured by superior mechanical properties and excellent structural functions, which have been a promising alternative to conventional alloys and steels in diverse industrial fields. Mechanical drilling is a compulsory operation to shape fibrous composites to desired workpiece quality and target dimensional accuracy. Progressive tool wear is an extremely crucial issue when drilling CFRPs as it may result in undesired machining consequences such as increased force generation, elevated temperatures, and deteriorated surface quality. Despite great endeavors already made to address the wear issues, a complete review of the wear phenomena for CFRP drilling is still significantly lacking. The present paper aims to report the key research advances in tool wear aspects when drilling CFRPs. The wear phenomena, wear modes, and tool failure mechanisms are carefully reviewed. The effects of wear progression on various drilling outputs of CFRP laminates, such as drilling forces, cutting temperatures, and surface quality attributes, are discussed. A particular focus is placed on the quantification and assessment of tool wear during drilling CFRPs. Some research prospects for both academia and industry are outlined. The paper intends to offer a comprehensive understanding of wear mechanisms controlling the drilling of CFRP laminates.

“…It has been seen as a high point angle tool due to its more contact area between the wedge and the composite surface producing high thrust force. Defects like surface roughness and circularity error occurred during the drilling also affected by the thrust as well as the corresponding torque [6]. The torque is reportedly the influential parameter in controlling these surface defects while drilling the fibrous composite materials.…”

“…The difference in mechanical and thermal properties of this constituent matter makes the drilling process even more complex. The shearing action between the wedge shape drill tooltip and the composite laminate when the former tries to get into the latter cause the detachment of the fibers from the matrix initiating the hole-making process [6]. The top surface of the laminate is prone to drilling defects as the drill tool tries to push the material rather than cutting it and the fragile force of attraction between the constituents acts as a catalyst for it [7].…”

Carbon fiber reinforced plastic laminates have been kept under the category of hard-to-machine materials despite having some unmatchable properties like high strength, stiffness, corrosion resistance, etc. The heterogeneous nature of the material makes the essential secondary machining process a challenging task to perform. Drilling is always considered the effective way to drill holes necessary for the assembling purpose in structure building. Though, drilling the CFRP laminates critically affected by the abrasiveness of the reinforcing fibers eventually produces various defects. In this particular experimental analysis, a decision-making model associated with the Multi-objective optimization of ratio analysis (MOORA) method has been used in selecting the best possible parameter setting for minimizing defects. The results suggested that this method is found to be effective in solving the real-world problem of selecting the optimized parameter setting in drilling CFRPs. The best possible combination of low point angle, high speed, and low feed rate produces the least drilled hole defects.
