Experimental results obtained were compared with the empirical results. For the experimental studies, a Kistler 9257A three component (Fc, Ff and Fp) piezoelectric dynamometer was used to measure cutting forces. This dynamometerwas associated with a 5019 B130 charge amplifier connected to a PC running Kistler Dynoware force measurement software. The empirical results were obtained through Kienzle approach. Five different cutting speeds, five different feed rates and two different depth of cuts were used in the experiments. It was observed that cutting forces decreased as the cutting speed increased and increased by the feed rate. Experimental results also showed similar trends with the empirical results. At the end of experiments, it was observed that surface quality increased by with increasing cutting speed and decreased with increasing feed rateOpravljena je bila eksperimentalna raziskava glavnih rezalnih sil na rezalno orodje v odvisnosti od rezalnih parametrov pri obdelavi jekla AISI 1117. Pridobljeni eksperimentalni rezultati so bili primerjani z empiričnimi rezultati. Rezalne sile so bile pri eksperimentalni raziskavi merjene s trokomponentnim (Fc, Ff in Fp) piezoelektričnim dinamometrom Kistler 9257A. Dinamometer je bil povezan z nabojnim ojačevalnikom 5019 B130, priključenim na osebni računalnik s programsko opremo za merjenje sil Kistler Dynoware. Empirični rezultati so bili pridobljeni s Kienzlejevim pristopom. V eksperimentih je bilo uporabljenih pet različnih rezalnih hitrosti, pet različnih podajanj in dve različni globini reza. Ugotovljeno je bilo, da se rezalne sile zmanjšajo s povečanjem rezalne hitrosti oziroma povečajo s povečanjem podajalne hitrosti. Eksperimentalni rezultati kazejo podoben trend kot empirični rezultati. Ob koncu eksperimentov je bilo ugotovljeno, da se kakovost površine izboljša s povečanjem rezalne hitrosti in zmanjša s povečanjem podajanjaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
