Sažetak
Kod mašinske obrade laserom geometrijski precizno rezanje FRP kompozita predstavlja zadatak pun izazova pošto treba napraviti što kvalitetniji rez. Cilj istraživanja je da se odrede optimalne vrednosti parametara rezanja da bi se dobio geometrijski precizan rez kod BFRP kompozitnog laminata debljine 1,60 mm. Eksperimenti su izvedeni primenom pulsnog Nd:YAG lasera sa napajanjem od 250 W. Izvor svetla, širina impulsa, frekvencija impulsa, pritisak komprimovanog vazduha i brzina rezanja su varirani da bi se procenile različite karakteristike kvaliteta reza: širina gornjeg i donjeg dela reza, odstupanje gornjeg i donjeg dela reza i suženje reza. Rezultati eksperimenta su iskorišćeni za izdvajanje indeksa optimizacije većeg broja karakteristika kvalitetnog reza. Genetski algoritam i grej relaciona analiza su iskorišćeni u postupku optimizacije. Utvrđene su optimalne vrednosti parametara rezanja: umereno napajanje izvora svetla (184,5 Amp), manja širina impulsa (2 ms), pritisak komprimovanog vazduha (8 kg/cm²), brzina rezanja (50 mm/min) i veća frekvencija impulsa (30 Hz). Konfirmatorni eksperimenti su potvrdili da optimalne vrednosti parametara rezanja mogu da poboljšaju gornji deo širine reza, donji deo, odstupanja kod gornjeg dela reza, odstupanja kod donjeg dela i suženja reza za 13,33%, 13,29%, 23,52%, 23,07% i 10,83%. Rezultati eksperimenta su takođe potvrdili da je napajanje izvora svetla najvažniji parametar za sve karakteristike kvaliteta reza.
