“…When an evaluation is made in general, it is seen that the highest level of damage occurs when drilling a flat surface compared with other surfaces parallel with the thrust force results. On the other hand, Geier et al 10 analyzed and illustrated that when drilling convex curved surface, the angle between the cutting lip and workpiece has larger value compared to the flat surface drilling operation, which makes drilling operation as if a smaller tip angle tool is used. In literature, it was stressed that lower cutting forces and damaged holes can be obtained using smaller point angle tools.…”

“…In literature, this angle value is expressed by subtracting half of the point angle value of the cutting tool from 90°. 10 Value of the angle varies for different surface curvatures as shown in Figure 1 (θ 3 < θ 1 < θ 2 ), even if the same cutting tool is used. This is similar to drilling the same material with tools that have different point angles.…”

“…Especially tubular composites are preferred in frame structures. 3,10 Conventional drilling operation is inevitable for the assembly of these composite structures. However, during conventional drilling, macro-sized damages (delamination and uncut fibers) and micro-sized damages (pull-out, debonding, matrix cracks, fiber breakages) occur due to the layered and anisotropic structure of the composites.…”

“…In these studies, the influence stacking sequence of carbon and glass layers on thrust force, drilling-induced damages, and surface quality were researched. Geier et al 10 focused on drilling of curved CFRP composites. Drilling of a flat plate and convex curved surface were experimentally investigated and compared considering burr formation.…”

Composites used in many fields today are produced by different methods and have different surface curvatures and geometries. Thus, these materials can exhibit different behaviors in terms of machinability characteristics as well as mechanical tests. Drilling operation is an inevitable process for assembly operations of many parts, and in some cases, concave/convex composite parts must also be drilled. In this study, drilling machinability of flat, convex, and concave curved carbon fiber reinforced plastics were investigated experimentally. The machinability was evaluated considering thrust force, delamination formation, and borehole damage analysis. The experimental results demonstrate that the largest thrust force and damage occurs when drilling the flat surface, while the least ones occur when drilling the concave curved surface, in general. In addition, while the damage caused by drilling is severe on the flat surface, higher quality holes were obtained on the concave curved surface at the same cutting parameters.

“…Besides, Geier et al (2021) examined and weighed the emergence of burr during the drilling of carbon fiber reinforced polymer composites considering both curved and flat plates with complicated geometric studies. The principal parameters considered are the burr attributes, feed rates, cutting speeds, and curved plate's radius.…”

The present state of competition within the plastic composite industry calls for efficiency to be competitive. However, in the drilling of carbon-fiber-reinforced plastic (CFRP) composites, the process engineer still lacks knowledge of the priority of parameters as parameters are chosen at random, and resources are deployed without justification on their importance and strength. Consequently, production crises and productivity losses persist. In this article, the analytic hierarchy process (AHP) method is deployed to evaluate the weights of criteria in a CFRP composite drilling operation. The establishment of the decision, alternatives, and criteria is accomplished, and pairwise comparisons are conducted to allow the computation of the importance weight of each criterion. The weight is then established. The proposed approach was illustrated with experimental data from the literature with a plastic drilling case. Six criteria were chosen as crucial in determining the drilling parameters of CFRP composites. The results reveal the following: thrust force (0.413), torque (0.253), eccentricity (0.151), surface roughness (0.115), delamination at entry (0.037) and delamination at exit (0.030). In a validation exercise to ascertain the consistency of the analysis, a consistent analysis was obtained. The novelty of the article is using the AHP approach on the drilling of CFRP composites. Practically, these results impact operator training, indicating that attention should be focused on thrust force control. The industrial applications of CFRP composites include the basic structures of automobiles, ships, and airplanes.
