This paper presents an evaluation of the machining efficiency of glass fiber reinforced polymer (GFRP) composites reinforced with multi-walled carbon nanotubes (MWCNTs) using Taguchi and Critic-CoCoso methods. In the study, the effects of machining parameters on surface roughness, delamination and thrust force of CETP materials doped with different ratios of multi-walled carbon nanotubes in drilling operations with different tool types were investigated. The experiments were planned according to Taguchi L27 orthogonal arrangement and the effects of each control parameter on the outputs were determined by S/N ratio method.
The study aimed to determine the optimum values of the parameters used in the processing of GFRP matrix composite material. The fact that the number of outputs obtained is more than one requires that the effects of different and conflicting response values on each other should also be taken into account. For this reason, multi-criteria decision making methods (MCDM), which are frequently used in practice, are used to evaluate all outputs as a single objective function. First, the data were weighted with the Critic method to ensure the minimization of all output values, and then a comparative analysis was made using the Combined Compromise Solution (CoCoSo) method, one of the multi-criteria decision making methods.
