The results indicated that there is a significant connection between the dynamic character of the cutting force in abrasive waterjet machining, namely, peaks in the cutting force signal, with the appearance of irregularities and uncut parts in the machined surface. Also, the research showed that the increase of the traverse speed produces an increase in the mean value of the static component of the cutting force. In experiments, the vertical component of the cutting force has been measured for an Aluminium AlMg3 12 mm thick rod cut at traverse speeds from 900 mm/min to 1100 mm/min. Cutting with higher traverse speeds yields more irregularities, which are connected with the appearance of peaks in the measured cutting forceV članku so predstavljeni rezultati raziskave o vplivu hitrosti premikanja na rezalne sile in obdelano površino pri obdelavi z abrazivnim vodnim curkom. Rezultati so pokazali, da obstaja pomembna povezava med dinamičnim značajem rezalne sile pri obdelavi z abrazivnim vodnim curkom, natančneje med vrhovi v signalu rezalne sile, ter pojavom nepravilnosti in nerazrezanih delov na obdelani površini. Prav tako je raziskava pokazala, da povečanje hitrosti pomikanja povzroči povečanje srednje vrednosti statične komponente rezalne sile. V eksperimentih je bila izmerjena navpična komponenta rezalne sile za 12 mm debelo palico iz aluminija AlMg3, rezano s hitrostmi premikanja od 900 mm/min do 1100 mm/min. Pri rezanju z večjimi hitrostmi se pojavijo večje nepravilnosti, ki so povezane s pojavom vrhov v izmerjeni rezalni siliTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
