The adjusted delamination factor (F-da) was used to assess delamination. The experiments were carried out using a brad spur drill (Tool 1), a twist drill (Tool 2), and a dagger drill (Tool 3) tool. A multi-mapped image processing model (MMIPM) was developed for an advanced and comprehensive delamination assessment in images by evaluating F-da and UCF parameters. In order to provide more information about the preferential orientation of delamination, in addition to F-da, conventional delamination factor (F-d) and minimum delamination factor (F-dmin) were calculated and a comparison of all delamination approaches was performed. Furthermore, the PROMETHEE-GAIA method was used to perform multi-objective optimization of F-da and UCF. The minimum F-da and UCF values were achieved with the twist drill (Tool 2). Vc = 118 m/min and f = 0.156 mm/rev were optimal conditions for minimum F-da and UCF.eninfo:eu-repo/semantics/closedAccessFiber metal laminateCARALLDelamination factorUncut fiberDrillingImage processingOptimizationArticle441110.1007/s40430-022-03806-2Q3WOS:0008627357000042-s2.0-85139235741Q2
