cutting speed = 75 m/min, feed rate = 0.2 mm/rev and depth of cut = 0.5 mm. Shahrajabian and Farahnakian deployed PSO to optimize the material removal rate in CFRP milling, where the cutting force and surface roughness served as constraints. The maximum material removal rate was achieved at spindle speed= 3630 rpm, feed rate=353 mm/min and depth of cut = 6 mm. Isik et al. optimized the drilling hole surface roughness using SA. The optimal drilling parameters were identified as: feed rate=0.2 mm/rev, cutting speed = 89.9 m/min, tip angle=119.9° and flute number = 4. Norcahyo et al. optimized the hole delamination damage using ACO and the obtained optimal drilling parameters were drill point angle = 116°, feeding speed = 51.3 mm/min, and spindle speed = 4975 rpm.
