Optimal and critical cutting parameters were determined. It was found that the cutting speed must be selected above 400-500m/min in order to prevent BUE and BUL formation when machining of AA6351 (T6) alloy with uncoated carbide inserts. The results of this study show that the most important parameter affecting main cutting force and surface roughness is feed rate. As a result of this study, optimum cutting force and optimum feed rate were found in order to minimize surface roughness of the work pieceV predstavljenem prispevku so eksperimentalno preučeni vplivi parametrov obdelave kot sta rezalna hitrost) in podajanje na nastanek nalepka, glavno rezalno silo in površinsko hrapavost. Določeni so bili optimalni in kritični rezalni parametri. Ugotovljeno je bilo, da mora biti rezalna hitrost pri obdelavi zlitine AA6351 (T6) z neoplaščenimi karbidnimi ploščicami višja od 400-500 m/min, da ne pride do nastanka nalepka. Rezultati raziskave kazejo, da ima največji vpliv na rezalno silo in površinsko hrapavost podajanje. Kot rezultat raziskave sta bila določena optimalna rezalna sila in optimalno podajanje za minimalno površinsko hrapavost obdelovancaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
